Chapter 488 The Lithium Dendrite Problem Solved

Especially some of the materials that need to be used, she had to go to several laboratories to borrow them from others.

Fortunately, I borrowed it. If I didn't, it would be hard for a clever woman to cook without rice.

Therefore, just improving this material, she spent two days, Saturday and Sunday, unable to carry out the next experiment at all.

Because, she had to go back to class on Monday, and other people in the laboratory were waiting to use it, so it was impossible to reserve it for her alone.

Therefore, if she wanted to do the experiment, she had to wait until the next week.

"Girl, what's wrong?"

Cai Guozhong also heard about Cen Li's visit to the Institute of Physics, so he wanted to come over to have a look, but he didn't expect to meet her with a sad face.

"I don't have enough time, I need to go back to school, and the experiment is only half done." Cen Li didn't hide it, and told Cai Guozhong about the difficulty.

"Well, you're right to tell Grandpa Cai, let's go, I'll take you to a good place." Hearing this, Cai Guozhong patted Cen Li on the shoulder and led her away.

Not long after, Cai Guozhong came to a laboratory, and Cai Guozhong opened the door to let Cen Li in.

When she got inside, Cen Li was shocked. The experimental equipment here was more complete than the laboratory she stayed in before.

"This is the exclusive laboratory of an old friend. Recently, he has just completed a research, and it is temporarily vacant, so I will use it for you."

Cai Guozhong said, and handed the key to Cen Li, "But you have to make sure that you have to take good care of the things in the laboratory."

Cen Li quickly took it, and said happily, "Grandpa Cai, don't worry, I guarantee that the laboratory will be returned as it is."

"That's fine, let's go, you haven't eaten yet, Grandpa Cai invites you." Cai Guozhong nodded with a smile, and took her to the cafeteria together.

After dinner, Cen Li was not idle after returning to the dormitory, picked up a pen and continued to draw cartoons.

There is no way, time is too precious for her, and a minute and a second cannot be wasted.

In the following time, Cen Li went to the research institute to conduct experiments at noon and evening while attending classes.

A week later, Cen Li finally succeeded!

The morphology of deposited lithium on the MPDMS anode proves that it has the advantage of preventing the formation of lithium dendrites.

After Li plating/stripping at 0.5 mA cm-2 for 10 h with a capacity of 0.25 mAh cm-2, the typical Li dendrite morphology appears on the blank Li anode, which is caused by the uneven Li deposition and dissolution process .

The carbonate-based electrolyte-induced SEI layer is fragile and cannot withstand the large volume fluctuations during Li deposition/stripping cycles, resulting in SEI rupture and Li dendrite growth.This explains the short-circuit phenomenon of cells with blank lithium anodes.

While the MPDMS-10 anode benefits from a relatively uniform lithium deposition process, the lithium deposition on the top surface remains uniform after cycling without the growth of lithium dendrites.

Coarse-grained molecular dynamics verified the effect of SEI uniformity on the morphology of deposited lithium metal: the more uniform the SEI, the denser and more uniform the deposited lithium configuration is, which is consistent with the experimental results.

This result made her smile with satisfaction.

After saving all the data, Cen Li cleaned the laboratory and confirmed that everything was the same as when it was borrowed, and then closed the door to find Cai Guozhong.

Seeing Cen Li come to return the key, Cai Guozhong was a little surprised, and asked with a kind smile, "Have you finished the experiment?"

Cen Li nodded, "Well, the lithium dendrite problem has been solved."
