1. Article Abstract Structural instability and stress accumulation-induced cycling degradation of silicon anodes have hindered their practical application in next-generation high-energy-density lithium-ion batteries (LIBs). Recently, M.S. Jiahao Chen and Prof. Hui Yang from Nanjing University of Technology (NUIST) developed a…
Cathode, anode, electrolyte and separator are the four main materials that make up lithium-ion batteries. During the charging process of a lithium-ion battery, lithium ions are detached from the cathode transported through the separator through the electrolyte, and then embedded…

1. Preface Model coin cell battery is a kind of battery used by lithium researchers, it is composed of a single layer of positive and negative electrode and diaphragm, but due to the binding of the positive and negative electrode…
1. Author Information and Article Abstract In 2022, Dr. Li Chuang of Tsinghua Shenzhen Research Institute developed a solid-state lithium-sulfur battery (Li-SPAN) with a salt-coated polymer electrolyte. In this structure, sulfur is fixed in the polyacrylonitrile substrate during cycling, the…
1. Preface The cell voltage and internal resistance of lithium-ion battery are two important battery parameters. Accurate and rapid characterization of these two parameters is the key to monitor the battery production stability and battery status, and improve the efficiency…
1. Preface The conductivity of the solid-state electrolyte and its overall cycle performance are greatly influenced by factors such as density, roughness, and integrity of the pressed solid electrolyte sheet. Moreover, stable and consistent pressure during testing is vital for…
1. Background Solid state electrolyte is a type of material capable of ion conduction in the solid state, playing a crucial role in the performance of all-solid-state lithium-ion batteries. Compared to traditional liquid-state lithium-ion batteries, solid-state batteries feature electrolytes composed…
