Hand rubbing nuclear fusion live in the wilderness

Chapter 265 Sacrifice a Lithium Battery Obtained by a Professor

In the breeding farm, Han Yuan cleaned out the messy gravel and bricks, and tidied up the damaged factory building a little bit, and piled up the damaged walls to prevent the remaining animals from running out.

As for the South American marsh deer and alpacas that died on the ground, the Korean won didn't plan to ask for it.

The death of these animals is so tragic that people can't help it at all.

The ones that were crushed to death by bricks and stones were better, but there were a few others, it was not known whether they were flattened by the boa constrictor or entangled.

Anyway, his whole body was covered in blood, except for his head, his chest cavity and abdomen were almost collapsed into a piece of paper.

There were bloodstains everywhere on the ground, and even though it was still raining lightly, there was a bloody smell that couldn't be concealed.

Even Han Yuan has a strong heart, but when he saw these dead animals, he couldn't help feeling sick.

After cleaning up the gravel, Han Yuan dragged the dead animals to the other side, returned to the studio, took a shovel and a hoe, and dug a deep pit for burial.

If it wasn't rainy and it was not easy to cover the lime, he planned to cover it with some lime to sterilize and kill the virus, so as to prevent any problems.

The tragic death is on the one hand, and on the other hand, it is worrying that there will be some bacteria, viruses, parasites and the like attached to these dead animals.

Snakes are notoriously dirty.

This dirty does not refer to other things, but refers to the fact that it has a lot of bacteria, viruses and parasites.

After coming to this simulated world for more than two years, Han Yuan ate a snake once, and he ate it when he was short of food for the first time in the wilderness.

When eating, not only the skin is peeled and bled, the internal organs are all cleaned up, but when it is roasted, it is roasted for [-] minutes before it is cooked through.

After handling the farm, Han Yuan called out to the two little ones, and led them back to the living room.

In addition, he brought the capuchin monkeys back to the camp and placed them near the camp.

After repeatedly telling the two children and the capuchin monkey not to go out and run around tonight, Han Yuan modified the trigger warning device and connected it to the high-voltage power grid.

As long as the warning device is triggered, the high-voltage power grid will be automatically connected to the power supply immediately, and the high-voltage electricity of thousands of volts will kill all creatures that trigger the trap device.

Of course, in order to prevent small animals from triggering the early warning device, South Korea replaced the multiple wires used for early warning with multiple iron wires.

Without a certain amount of strength, these wires cannot be broken.

This can effectively prevent any birds and small animals from triggering the early warning device.

After finishing these things, Han Yuan took a shower, put on clean clothes and went to the dust-free studio, bringing a bag of hand-ground coffee beans and a simple hot water pot by the way.

He was already prepared to stay up late tonight, and he might not even be able to sleep tomorrow.

Pushing open the door of the dust-free studio, putting on shoes and protective clothing, Han Yuan said: "The main components of a battery are two parts, the electrolyte, the cathode and the anode."

"I have completed the manufacture of these two things during the day today, but this does not mean that they can be assembled and used."

"Tonight I need to solve one of the most common and deadly problems in lithium-sulfur batteries, lithium dendrite formation."

"I have talked about how to deal with the problem of lithium dendrite formation when preparing the electrolyte before."

"Friends with a good memory should still remember what method I am going to use this time."

Hearing this, the barrage popped up instantly.

Han Yuan smiled, and continued: "That's right, the method used this time is the method of inhibiting growth."

"By artificially manufacturing the SEI film to replace the self-extending SEI film on the original lithium-sulfur battery to suppress and alleviate the problem of lithium dendrite formation."

"Compared with the guided method, the production tool of the inhibited growth method is simpler and more suitable for assembly line production."

While talking, Won moved the materials for preparing the artificial SEI film out of the locker in the corner.

"Actually, the artificial SEI film I'm going to prepare this time has already been explained when I prepared the electrolyte, cathode and anode."

"This is a robust artificial solid electrolyte mesophase film with 'bionic ion channels' and 'high stability'."

"The name is: 'Organometallic framework composite flexible lithiated binder composite'."

"It uses zirconium as the metal framework, combined with perchlorate ions, composited into an organometallic framework and mixed with a flexible lithiated binder to obtain a solution similar to a non-Newtonian fluid."

"Finally, coating the surface of the treated cathode lithium can effectively solve the problem of lithium dendrite growth."

For what Han Yuan said, most of the audience in the live broadcast room basically had a half-knowledge.

However, experts in materials science from various countries can basically understand the principle after listening to it.

In Huaguo, Chen Jun, a professor at Nankai University, stared at the live broadcast without blinking.

As an expert in inorganic chemistry, he was selected as an academician of the Academy of Sciences for the [-] year for his representative achievement of synthesizing stable conductive nano-spinel at room temperature.

The direction of Chen Jun's research is the electrodes of lithium-ion batteries.

The micro-nano multi-electrode structure electrode he developed has greatly improved the safety of the battery and is widely used in various batteries. Perhaps the mobile phone you are currently holding has the results of this old professor.

As a top expert in this industry, Chen Jun was naturally recruited by the upper echelon as one of the leaders in the research of replica lithium-sulfur batteries.

[Using the strong affinity of zirconium metal ions to nitrogen, oxygen, sulfur and other ions as the basis, combined with the high electronegativity and sulfophilicity of perchlorate ions, the SEI film is endowed with excellent single-ion conductivity and high lithium ion migration number and excellent ionic conductivity. 】

[And after such a thin film covers the original lithium metal surface, it does not affect the conductivity of the lithium cathode at all. 】

[At the same time, it can also effectively prevent the adverse reaction between lithium metal and electrolyte, so that the electrolyte cannot contact the lithium cathode, and the growth of lithium dendrites can be naturally inhibited. 】

[This is simply a genius idea! 】

After watching the whole live broadcast of Won, Chen Jun muttered to himself and took off his glasses, which were over 600 degrees Celsius, and rubbed his sore and dizzy eyes, but he didn't expect that his eyes suddenly went dark, and he fell down slowly. go down.

Suddenly, the entire laboratory was in chaos.

When South Korean Won announced the preparation of lithium-sulfur batteries with high energy storage, the 60-year-old professor forcibly adjusted his time difference to that of South Korean Won in order to watch the live broadcast as soon as possible.

Originally, with the assistance of the medical staff, there were no major problems, but Won had an accident, and after the broadcast, the interlude was started.

The inserted content is the key to solving the problem of lithium dendrite growth.

So Professor Chen Jun, who was just about to rest before, got up from the bed immediately after receiving this notice.

However, after two consecutive live broadcasts, the gray-haired old professor finally couldn't bear it and passed out.
