Recently, Peng Haofeng, an undergraduate student from the 2022 cohort at the School of Materials and Energy, University of Electronic Science and Technology of China, majoring in New Energy Materials and Devices, has published a research paper in the prestigious Journal of Colloid and Interface Science, a well-known journal in the field of materials science. His paper reports on significant advancements in the realm of organic-based solid-state lithium metal batteries.

In his innovative approach, Peng selected 2,2,2-trifluoroethyl acrylate as a key component and further enhanced its coordination effect by incorporating vinylene carbonate. This strategic move allowed for precise regulation of the solvation structure, effectively liberating free lithium ions while suppressing anion migration. As a result, he successfully designed a solid-state electrolyte and battery system that exhibits exceptional performance.

This solid-state battery is capable of maintaining stable cycling for over 550 cycles at a 0.5C rate, boasting a capacity retention rate of 96.5% and an average Coulombic efficiency surpassing 99.9%. Moreover, it continues to perform admirably even under conditions of short circuits or mechanical cutting, showcasing its immense potential for commercial applications.
