"With this membrane, the two links of lithium battery recycling, leaching and extraction, can be directly integrated into one."
"In this way, it seems that we don't need a large space, just build an integrated recycling equipment."
"Throw batteries here, spit out various battery metal elements over there."
"In the future, it will be further miniaturized and can be mounted on drones, oceans, moons and other places for mining."
With this abnormal biofilm.
Chen Yi quickly decided not to build a large-scale chemical equipment set, but to directly build an integrated lithium battery recycling equipment.
"Before determining the equipment design, experiments are needed to determine the adsorption efficiency and adsorption capacity of the biofilm."
"Also, the most important thing is to adjust and improve the biofilm that absorbs all metals into a biofilm that absorbs elemental metals."
Chen Yi looked at the property interface of the biofilm in front of him.
Said without politeness.
This biofilm is so crazy that it has wiped out all the metal elements in the entire periodic table.
It’s not an exaggeration to call it a metal gluttonous film.
Evaluate based on system notes.
Through the conductivity and absorption rate of different metals, metals can be classified and adsorbed.
But after several virtual chemistry teachers taught through words and deeds.
Chen Yi understood very well that even if the absorption rates are different, when most of the reactions are carried out, there will still be some other substances involved in the reaction.
This is something that reacts together.
If purification is not carried out, this will affect the texture of the material.
If you choose purification, the cost will go up again.
This problem must be solved from the root.
Chen Yi could only adjust and improve this all-metal-killing biofilm into a single-metal elemental membrane.
For example, if you need lithium, take out the lithium biofilm.
If uranium is needed, then take out biofilms targeting uranium.
According to this idea and direction.
Chen Yi prepared a cup of solution rich in various gold elements in the laboratory.
Take a cut piece of biofilm, simply measure the area, and start the experiment.
"21.3 square centimeters, in units of 5 seconds."
Place the biofilm on the test stand, the instrument automatically pours the solution, and the test stand begins to rotate to maximize the contact between the biofilm and the solution.
After 5 seconds, the solution was drained.
Chen Yi looked at the translucent yellowish-to-black biofilm, dried the moisture on the surface, and then measured the weight.
7.81 grams more.
"This speed is a bit amazing."
Chen Yi was a little surprised.
These 7.81 grams are undoubtedly the metal elements adsorbed by this biofilm within 5 seconds.
You know, this is just a 21.3 square centimeter biofilm.
If the biofilm is rolled up to increase the contact area per unit time, the adsorption efficiency will increase exponentially.
"Again."
Pour the solution in a second time.
Rotate again to increase contact and drain after 5 seconds.
Chen Yi dried the biofilm and measured its weight.
15.63 grams more.
Subtract the 7.81 grams from the first time.
The weight adsorbed this time is 0.01 more.
The third time. The weight increased by 7.8 grams, but the adsorption efficiency remained stable.
The fourth time, it was still 7.81 grams, and the adsorption was still stable.
The fifth time, with an increase of 6.27 grams, the adsorption efficiency dropped by a little more than 20%.
The sixth time, 5.03 grams was added, reaching the adsorption limit of the biofilm.
"Unit square centimeter, the adsorption efficiency is 73 milligrams per second, and the total adsorption capacity reaches 2 grams."
"The efficiency of this biofilm is a bit scary."
Chen Yi looked at the total weight of 42.6 grams six times with a hint of shock in his eyes.
This is no longer adsorbing metal, this is considered eating metal.
You know, the biofilm before adsorption.
Its own weight is 21.3 square centimeters, which is only a little more than 6 grams.
After absorbing metal elements, its own weight increased by more than 8 times, which is not so much for absorbent paper.
"As for extracting the adsorbed metal, this is simple."
Chen Yi wore rubber gloves and picked up the biofilm, which weighed almost 50 grams, and threw it aside.
After some heating.
Biofilm dissolves and vaporizes.
Only a small ball of black powder rich in various metallic elements was left in the crucible.
Chen Yi simply replaced and restored the powder, took it out and put it on an electronic scale to get an accurate weight.
"42.56 grams, it seems part is missing."
After recording all the data, Chen Yi began to adjust the properties of the biofilm.
Colorful lights bloom.
Cover the remaining small piece of biofilm.
Wait for the light to dissipate.
The biofilm in front of me changed color.
From yellowish to transparent, it turned into silvery white and translucent.
[Item: Metallophilic Biosorption Membrane]
[Attributes: Strength x29.2, alkali metal x109.2, alkaline earth metal x29.5, transition metal x25.1, main group metal x28.4]
[It is detected that a certain attribute exceeds the initial value. Do you want to read the information? whether! 】
[Note: This is a biofilm with crazy affinity for alkali metals and strong adsorption capacity for other metal elements.
In front of it, no alkali metal ion can escape the fate of being adsorbed.
At the same time, it has great strength and can withstand huge pressure without breaking.
With the help of pressure and alkali metal affinity, it can easily crush and break up all alkali metal compounds. 】
"Read!"
Chen Yi did not hesitate and chose to read the information.
In an instant, a special biofilm structure and basic principles, as well as corresponding chemical and biological preparation methods, emerged in my mind.
With the assistance of the system, Chen Yi quickly digested this technical information.
Then, through the brainwave sensing headband, the production methods and technologies are uploaded to the supercomputer.
"Xuan Nu, prepare an alkali metal adsorption film and send it over."
"Received your order."
Xuannv responded.
It was quick, less than thirty minutes.
A small piece of biofilm as small as a fingernail was prepared and sent over.
Chen Yi manually divided the biofilm into two halves, and the attribute interface popped up.
[Item: Alkali Metals - Biosorption Membrane]
[Attributes: Strength x29.2, lithium x86, potassium x86, rubidium x86, cesium x86, francium x86]
[Note: This is a biofilm with crazy alkali metal affinity.]
"It's simply the nemesis of alkali metals."
"But at the moment, I only need lithium."
Chen Yi did not hesitate and quickly adjusted his attributes.
[Lithium: 86→139]
[It is detected that a certain attribute exceeds the initial value. Do you want to read the information? whether! 】
Soon, the properties of lithium changed from 86 to 139, reaching the limit of artificial semipermeable membranes.
After reading the information, Chen Yi sent the relevant technical information to Xuannv as usual.
Next, Chen Yi followed the same method.
"Excessive element biosorption membranes" were prepared respectively.
Increase the adsorption properties of the cobalt element to the highest level, read the technical information, and send it to Xuannv.
There are also bioabsorbable films of metal elements contained in lithium batteries such as manganese and nickel, and the reading technology is sent to Xuannv.
"After the biofilm that absorbs and extracts various elements is completed, the next step is the integrated equipment for lithium battery recycling."
"The discharge, crushing, leaching, and other extraction steps are fine. It is the discharge step that is a bit difficult for the equipment."
Chen Yi frowned and saw the discharge steps before the lithium battery was shattered.
Now on the market, either liquid nitrogen is used to freeze to an extremely low temperature, puncture short circuit to force discharge, or electrolyte is used to chemically discharge.
"If you want to make integrated equipment, the problem of this discharge link must be solved, otherwise the equipment will be easily scrapped."
"I just looked at the literature, and there seems to be an Eagle Sauce. Oh, it's the Li-Cycle Company of Massachusetts."
"A mechanical method is used to reduce the size of the battery without discharging, and then the technology of leaching the battery's electrode material using hydrometallurgy is used."
"Mechanically reducing battery size. How does this feel a bit like the hydraulic method of a hydraulic press?"
A joke about hydraulic machines came to Chen Yi's mind.
Ever since we had a hydraulic press at home, we only had hydraulic presses at home.
"Really? You'll know after you try it."
"If it doesn't work, waste a virtual learning opportunity, or skip the discharging link and use the discharged battery for crushing and recycling."
"It just requires an upstream enterprise in the industrial chain, and it is also a chemical electrolysis enterprise that pollutes a lot. If we can't do it, we won't do it."
Chen Yi found several lithium batteries that had run out of power on the surface, but still had residual power inside.
Use a machine tool to simply cut a concave platform to help reduce the size of the battery, and then take the battery and platform to the hydraulic machine tool at the base.
Place the platform and battery and adjust the angle.
Chen Yi turned on the hydraulic press.
Bang!
The heavy metal pile began to sink, aiming at the battery and pressing hard.
Crunch!
Just two seconds.
There was a lot of smoke and a bad smell, and there was a subtle glow of fire.
Rising from the edge of the gap between the platforms.
Basic smoke sensor activates.
The surrounding exhaust fans rotate to suck out the smoke and smell.
Wait until the short circuit reaction of the battery ends.
Chen Yi put on his mask, took the infrared temperature controller, raised the hydraulic press and went over to check it, and came to several conclusions.
"The volume size has been reduced."
"The battery experienced a short-circuit reaction due to extrusion, and thermal runaway occurred, with the temperature soaring to 700 to 800 degrees Celsius in an instant."
"High temperature and short circuit caused a violent reaction, causing the battery to burn but not explode."
"In this way, if there is a special leach solution, it can not only leach out the electrode materials of the battery."
"It can also increase the difficulty of battery reaction and combustion, while cooling the battery and absorbing toxic gases produced by battery reactions."
"Would it be possible to avoid all problems by soaking the battery in such a leaching solution and squeezing and crushing it?"
Chen Yi opened his mind and quickly thought of a way to solve the problem of battery short circuit discharge.
After all, lithium batteries are recycled after they are used up.
Even if there is some unusable power left inside, this small amount of power cannot cause too much trouble.
In this way, the wet method can be used to cool down and at the same time increase the difficulty of the battery combustion reaction, which is very feasible.
Combustion is suppressed.
The so-called battery explosion will naturally not occur.
Just do it if you think of it.
Chen Yi conveyed his thoughts to Xuannv.
For the study of chemistry and biology.
Now Xuannv, who works in the laboratory every day, plays the leading role.
Buzz!
The supercomputer outside buzzed for a while.
More than ten minutes passed.
The four chemical formulas were passed back by Xuannv.
Indicates that these four chemical formulas are applicable to currently common ternary lithium, lithium iron phosphate, lithium cobalt oxide, and Yifei's carbon-silicon lithium.
Follow the directions of the chemical formula.
Chen Yi spent more than two hours carefully preparing three solutions of ternary lithium, lithium iron phosphate, and lithium cobalt oxide, and started the pile driving test of the hydraulic press again.
A special spray platform was designed.
A special leaching solution is poured in, so that the battery is immersed in it, and at the same time, it is continuously sprayed through the circulation system.
Chen Yi first applied the solution of lithium cobalt oxide.
Bang!
The pile head of the hydraulic press sinks and pile driving begins.
After a few seconds.
The heavy pile head sinks into a lithium cobalt oxide battery submerged in solution.
The spray system was turned on, spraying solution continuously to the battery and pile headband.
Gudu, Gudu.
A hydraulic press drives the pile to the bottom.
Two bubbles emerged from the solution.
Imaginary smoke, sparks, combustion and explosion, nothing happened.
Only the originally clear solution began to turn black and turbid.
It seems that a large amount of battery material has been leached into it.
"Perfect. Sure enough, the wet method must be used for mechanical piling and extrusion."
"The risk of dry pile driving and squeezing is too high and it is easy to get injured."
It was determined that there is no problem with wet piling extrusion and crushing.
Chen Yi spent five days after many experiments and improvements.
Finally, a prototype of an integrated lithium battery recycling equipment was designed.
This is a kind of rolling extrusion type, large-scale peanut oil pressing machine.
There is a feed port, and behind the feed port are two extrusion steel wheels with large torque that roll against each other.
The battery was squeezed by the steel wheel and the structure was damaged.
The next step is repeated grinding to ensure that the battery is crushed to the smallest particles.
The crushed battery powder is sent to the leaching area behind.
After a certain period of solution leaching, various valuable electrode materials contained in the battery powder will be leached out, and then adsorbed and extracted through the biofilm.
besides,
The equipment is also designed with a wet suppression circulation system.
Through the pipeline, the filtered leaching liquid is extracted and transported to the steel wheel extrusion area.
Suppresses the reaction and combustion caused by battery extrusion and short circuit, and simultaneously reduces the temperature.
Make sure that the process from the steel wheel extrusion to the subsequent grinding and grinding is immersed in a humid environment to avoid the risk of reaction.
For the entire set of equipment, the only consumable is the leaching solution.
However, because the leached electrode material will be continuously adsorbed and extracted by the biofilm, this only consumed leaching solution can also be recycled repeatedly in the equipment.
According to Chen Yi's calculations.
The entire leach solution can be circulated 700 to 800 times, after which the leaching performance will drop significantly.
From 99.9 percent leaching, down to 90 percent, to 80 percent.
Replace according to the standard of performance degradation.
On average, 1 kilogram of leaching solution can leach more than 1.3 kilograms of lithium element.
In addition to carbon-silicon cells, other different battery types can handle batteries ranging from 100 to 280 kilograms.
Calculated based on 50 kilograms of leaching liquid for one piece of equipment.
This piece of equipment can process more than ten tons of power batteries, greatly improving the utilization efficiency of the leach solution and reducing the difficulty of pollution treatment.
"Still missing the final biofilm."
Using machine tools and printers, a prototype is produced.
Chen Yi took a roll and spent several hours on it. Xuannv made the lithium metal bioadsorption membrane and cut off part of it.
[Item: Lithium Element-Biological Absolute Adsorption Membrane]
[Attributes: Strength x29.2, Lithium x139]
[Note: This is a biological adsorption membrane that is absolutely compatible with lithium metal and makes people crazy. No liquid lithium element or isotope can escape its adsorption. 】
"Absolute adsorption. This is simply the best equipment for doomsday technology."
Chen Yi took out a shell that had a water inlet and outlet like a water purifier filter, rolled the adsorption film into a roll and stuffed it in, and then installed it tightly.
Test it to make sure the water in and out is normal.
Chen Yi stuffed it into one of the several adsorption extraction ports reserved in the lithium battery recycling equipment.
Then he took the biosorption membrane of cobalt metal and cut off a part of it as well.
[Item: Cobalt element - biological absolute adsorption membrane]
[Attributes: Strength x29.2, Cobalt x139]
[Note: This is a product that is absolutely compatible with cobalt metal.]
"With this cobalt biosorption membrane, the so-called cobalt bomb deterrent on the other side seems to be bankrupt and scrapped again."
Look at the same abnormal properties of this cobalt adsorption film.
Chen Yi was stunned for a moment, and suddenly remembered a funny thing.
With this, even if the opponent is shooting cobalt bombs like crazy.
You just need to get some of these cobalt biosorption membranes in water source areas and living areas.
After adsorption for a period of time, recycle and destroy it.
The radiation threat of this cobalt bomb is self-defeating.
"I'm going to make a video of the experiment when I have time, and send it to the other party for a look."
Chen Yi smiled and stuffed the cobalt biofilm into other extraction ports of the equipment, followed by adsorption membranes for nickel, manganese and other elements.
All adsorption membranes are installed.
An interface appeared in front of my eyes.
[Item: Perfect Level - Fully Automatic Lithium Battery Recycling Equipment]
[Attributes: Strength x29.2, Lithium x139, Cobalt x139, Nickel x139, Manganese x139]
[Note: This is a perfect lithium battery recycling equipment beyond the imagination of the world. No element of the lithium battery can withstand its recycling deprivation.
As a perfect piece of equipment, any core accessory inside it can bring a billion-point shock to the world]
