According to foreign media reports, scientists have developed a new method, which they believe can significantly improve the service life, charging speed and safety of lithium metal batteries. Pennsylvania State University has developed a three-dimensional cross-linked polymer sponge that can be attached to the metal plating of the battery anode.

The lead researcher of this study, Wang Donghai, published in "Nature Energy" (Nature Energy) magazine "This project aims to develop the next generation of metal batteries." Wang Donghai said: "Lithium metal has been tested in batteries for decades, but there are some basic problems that hinder their development."
Under extra pressure, such as the fast charging methods required for electric vehicles, lithium-ion (Li) batteries are susceptible to dendritic growth—needle growth will reduce the battery ’s lifespan and may cause safety issues—including fire Or explode.
Wang Donghai said: "Our method is to use polymers on the metal interface of lithium ions." As a porous sponge, this material not only promotes ion transfer, but also inhibits deterioration. "This makes the metal coating free of dendrites, even at low temperatures and fast charging conditions," he said. The researchers conducted modeling work to understand the improvement of lithium metal anodes. Researchers say that the practical application of this work may make more powerful and stable metal battery technology an indispensable part of daily life. "
Wang Donghai also said: "In electric vehicles, it can increase the mileage of hundreds of miles before the car needs to be charged. It can also extend the battery life of smartphones." Wang Donghai believes that this technology will take the life of lithium metal batteries. Cycle up.
