Before returning to the college entrance examination, I became popular in the science circle

With Wu Tong in charge and guiding the direction in the right context, the progress in the research and development of lithium anode materials for new energy batteries is gratifying to the naked eye.After continuous experiments, inferences, and adjustments, the research team, under the leadership of Tao Ran and Ruan Chengxu, finally focused on C2H6OSi, dimethyl silicone oil.

This is a polymer used in various fields such as medicines, daily chemicals, food, construction, etc. Under the guidance of Wu Tong, the research team discovered that when dimethyl silicone is treated with special synthesis methods, it is The coating method is performed in a glove box filled with nitrogen. After the coating is formed, it will effectively suppress the shuttle effect of lithium dendrites, so that the lithium anode material can truly exert its excellent performance.

Dimethyl silicone oil appears as a colorless and transparent volatile liquid to extremely high viscosity liquid or silica gel. It is odorless, highly transparent, has heat resistance, cold resistance, small change in viscosity with temperature, water resistance, small surface tension, and thermal conductivity. , the thermal conductivity is 0.134-0.159W/(m·K), the light transmittance is 100%, dimethyl silicone oil is non-toxic and odorless, has physiological inertness and good chemical stability.

It has good electrical insulation, weather resistance, hydrophobicity, and high shear resistance, and can be used for a long time at -50°C to 200°C.It has excellent physical properties and can be directly used in moisture-proof insulation, damping, shock absorption, defoaming, lubrication, polishing, etc. It is widely used as insulation lubrication, shockproof, oil dust proof, dielectric fluid and heat carrier.And used as defoaming, release agent, paint and daily chemical additives.

They will focus their attention on this material, which is to determine the solution to coating and look for suitable coating materials. This is one of the selected options. What they are interested in is the good weather resistance of this material. Electrical insulation, chemical stability, and physiological inertness.

After one-by-one experimental screening, they conducted in-depth development of this material, and finally the nano-breathing arranged dimethyl silicone oil, referred to as C2 coating material, was born.

The final appearance of this material is a paste with extremely high viscosity and silver color. When applied in a directional position, it will quickly solidify. During this period, the special nano-respiration effect can exert its stability after certain treatments. The effect of containing lithium dendrites.

Dimethicone is too commonly used in the world. What is special is the special synthetic preparation method. Of course, although the properties of the treated special materials are excellent, this layer of coating material alone cannot solve the problem that has troubled the world for many years. The lithium dendrite problem must still be lacking!
The most critical technology is actually the special combed carbon nano-interlayer deduced by Wu Tong, which uses special dislocation combing to smooth out the shuttle effect of lithium ions and finally isolate the generation of lithium dendrites. The application of new energy lithium batteries can be analyzed into reality.

"Mr. Wu, have we succeeded?" Looking at the data displayed on the rechargeable battery tester, Tao Ran couldn't help but beam with joy.It has been a full 48 hours. Not only has no lithium dendrites been produced, but even the Coulombic efficiency has remained at an extremely high level. This is truly a breakthrough of the shackles of lithium dendrites!
Let new energy lithium batteries completely break through the upper limit and become promising.

"The experiment proves that we are right!" Wu Tong nodded with a smile, and the actual test revealed the true knowledge. After a month and a half, they did come up with promising breakthrough materials for new energy lithium batteries, C2 coating and C1 carbon plate.

If C2 coating is simply used, it can also suppress the lithium dendrites caused by the shuttle effect, but deposition will occur on the surface. If things go on like this, it will definitely have an impact on the battery and its lifespan will be correspondingly reduced.But compared to before, it was a world of difference.In fact, this small problem can be basically ignored for current battery manufacturers and current new energy electric vehicle manufacturers.

However, Wu Tong is always striving for excellence. Therefore, Wu Tong sought to solve the problem of deposits on the basis of coating, which can smooth out the shuttle effect and sort out the accumulation caused by the separation effect of lithium ions during the charging process.She saw in the latest literature that in the field of lithium-sulfur batteries, attempts are being made to fix the positive electrode material, a sulfur composite material, in the intervening carbon port, seeking to solve the shuttle effect caused by the dissolution of polysulfides in the lithium-sulfur battery reaction.It is possible to simultaneously improve the conductivity of the cathode and the utilization rate of sulfur.

There are many attempts, including using a porous conductive carbon skeleton to disperse active sulfur into the carbon material, improving the dispersion of elemental sulfur in the composite structure, and using the pore structure to adsorb polysulfides to limit their removal from the composite structure. Precipitate in and improve electrode reaction efficiency.

Wu Tong was inspired on this basis, and then derived the honeycomb porous combing negotiation, using the special porous design of the carbon plate to impact lithium ions on the negative electrode, combined with the coating material, and finally formed a perfect treatment plan for lithium dendrites, allowing Lithium metal can be successfully used as the best negative electrode material to perfectly display the excellent performance of lithium batteries!

"We have created another miracle, Mr. Wu, we have created another miracle!" After Wu Tong nodded in affirmation, the core team members who cooperated with the experiment couldn't help but cheered throughout the laboratory.

Their eyes were fixed on the ten groups of test experiments on the experimental table. In their eyes, the six groups without lithium dendrites were no less than looking at rare beauties. In fact, beauty to them was nothing more than Beauty and bones, on the contrary, this represents the progress of scientific research and the results of their learning and progress, which makes their eyes shine even more.

"Mr. Wu, Mr. Wu, is omnipotent! Whatever Mr. Wu points to, he is invincible!"

"Okay, okay, everyone, continue to record data and repeat the test. We need more test data to verify the stability of this solution. Don't give me any more ecstasy!
After we have compiled the proper data, I would like to thank everyone above and the C2 coating material patent sharing reward will be cashed to everyone after it is put into production and use! "

Wu Tong laughed. The young team and the lively joy did not suppress it too much. Therefore, after allowing the team to be overjoyed, she issued new requirements.If they let them praise her again, she would really think that she was an omnipotent god!
However, how is it possible? She is still in the mortal realm. All breakthroughs come from the accumulation of knowledge, not breakthroughs made out of nothing!

The success of one experiment is not a complete basis. The accumulation of stable test data for many times is the truly effective experimental data.They initially did ten sets of comparative experiments, four sets of coating plus carbon plate congratulations, four sets of coating combinations, and two sets of ordinary solution processes. The two sets of ordinary graphite solutions for comparison ended the task early, and the contrast was sharp!
