About lithium-ion batteries and a brief history of development

Lithium-ion batteries are currently divided into liquid lithium-ion batteries (LIB) and polymer lithium-ion batteries (PLB). Among them, the liquid lithium ion battery refers to a secondary battery in which Li+ intercalation compounds are positive and negative electrodes. The positive electrode adopts lithium compound LiCoO2 or LiMn2O4, and the negative electrode adopts lithium-carbon intercalation compound. Lithium-ion batteries are an ideal energy source for development in the 21st century due to their high working voltage, small size, light weight, high energy, no memory effect, no pollution, low self-discharge, and long cycle life. A brief history of the development of lithium-ion batteries Lithium-ion batteries and lithium-ion batteries are new high-energy batteries that were successfully developed in the 20th century. The negative electrode of this battery is lithium metal, and the positive electrode uses MnO2, SOCL2, (CFx)n and so on. It was put into practical use in the 1970s. Because of its high energy, high battery voltage, wide operating temperature range, and long storage life, it has been widely used in military and civilian small electrical appliances, such as mobile phones, portable computers, video cameras, cameras, etc., partially replacing traditional batteries.
