Shenzhen Institute of Advanced Technology has made progress in research on high-safety quasi-solid-state batteries

On October 14, the electrochemistry team of the Photonic Information and Energy Materials Research Center of the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, made important progress in the field of high-safety secondary lithium batteries . The related results were published in the top international energy journal Energy Storage Materials under the title of Reinforcing Concentrated Phosphate Electrolytes with In-Situ Polymerized Skeletons for Robust Quasi-Solid Lithium Metal Batteries. The first author of the article is Master's student Chen Jiahua, and the corresponding authors are Assistant Researcher Lu Ziheng and Researcher Yang Chunlei.

In addition, this study used the perturbation stability theory based on the Euler method to systematically discuss the stability problem of the interface between gel electrolyte and lithium metal, and deeply revealed the relationship between the polymer skeleton content, lithium ion conductivity, shear modulus and anti-lithium dendrite ability in the gel electrolyte, which has important guiding significance for the design of polymer electrolytes.
