Chapter 127: Material Science, LV3!

　　Professor Krell's assumption was right.

　　When he quickly returned to the laboratory, the sample placed on the field emission scanning electron microscope did not smoke, did not explode, everything was good surprisingly.

　　Through several sets of SEM images, it can be clearly observed that lithium ions are gradually deposited on the electrodes protected by a modified PDMS film, just like a beautiful layer of silver-coloured tundra.

　　However, this layer of "tundra" did not grow wildly as in other lithium batteries, and then develop deadly dendrites, but quietly lying under the modified PDMS film, gently undulating with the passage of time.

　　Nucleation did not take place, and, not surprisingly, this state will be maintained until the entire charging process is completed.

　　There was no doubt that they had successfully restored the experiment.

　　"Incredible ......"

　　Standing next to the computer, looking at the image continuously generated by the field emission scanning electron microscope next to him, Professor Krell said incredulous three times in a row, and still could not vent the shock in his heart.

　　Even though the same image had already been posted in Nature Chemistry, it was far less intuitive than seeing it with his own eyes.

　　Behind him, a reporter from Columbia Television looked confused, not understanding what these researchers were so happy about.

　　Even standing here witnessing the great moment, he couldn't see any mystery in these SEM maps.

　　Out of confusion, he spoke up.

　　"Professor?"

　　Professor Krell looked back at the reporter with a pleasant smile.

　　"Yes?"

　　He was in a pleasant mood now, very, very pleasant.

　　If the problem of the lithium dendrite was solved, his lab would directly benefit. It was believed that it wouldn't take long, at most one MRS meeting, for his lab to get tens of millions or even hundreds of millions of dollars of investment.

　　When the industry used how to abandon the lithium battery, now how to invite it back.

　　The reporter gulped and asked, "What's the situation?"

　　Professor Krell looked at him with an affirmative sight, "I can now tell you with responsibility that it has worked."

　　Perhaps feeling that his statement was not shocking enough, he paused for a moment and continued.

　　"Maybe in half a year, maybe in a year, you'll be able to use a smartphone with a week of standby. In a few years, you will be able to see Tesla ...... with a range of thousands of kilometres outside the PPT Believe me, my bragging is definitely more reliable than yours."

　　This statement may be exaggerated, but it is definitely not out of touch with reality.

　　Now lithium-ion batteries are mainly based on graphite anode, graphite's theoretical specific capacity of 372mAh/g, regardless of cost, the laboratory can make this number into 747mAh/g through graphene technology.

　　As for the theoretical specific capacity of lithium?

　　It's 3860mAh/g.

　　A lot of things can't be expressed directly by adding or subtracting, but you can still visualise the absolute advantage of this four-digit over three-digit figure from the numbers.
