The main characteristics of the battery cell are small particle size, large specific surface area, white color, high purity, and significantly improved electrochemical performance. It can be used in lithium titanate battery materials and cobalt lithium battery materials. 1: It exhibits typical Faraday pseudocapacitance behavior in the potential range of -0.05-0.35V (vs SCE). The so-called pseudo capacitor refers to the development of pseudo capacitors after double layer capacitors. Pseudo capacitance, also known as Faraday quasi capacitance, for Faraday quasi capacitance, the process of storing charges not only includes the storage on the double layer, but also includes the storage of charges in the electrode due to the redox reaction of ions in the electrolyte in the active material of the electrode. The ions in the electrolyte, usually H or OH -, diffuse from the solution to the electrode/solution interface under an external electric field, and then enter the bulk phase of the active oxide on the electrode surface through electrochemical reactions at the interface; Due to the use of oxides with a large specific surface area as electrode materials, a considerable number of such electrochemical reactions occur, and a large amount of charge is stored in the electrode. During discharge, these ions that enter the oxide will return to the electrolyte, and the stored charges will be released through the external circuit, which is the charging and discharging mechanism of Faraday quasi capacitors. To be clear, pseudo capacitors are countless small double layer capacitors. 2: At the same current density (milliamperes per square centimeter), increase the specific capacity (in grams). 3: Reduce self discharge rate and have good cycle life.
