Common in daily life is mainly mobile phone batteries, electric vehicles, trams, electric tool batteries.

　　1 From the shape division: cylindrical, square shape

　　2 From the shell data division: steel shell, aluminum shell, plastic shell, aluminum plastic film (soft bag)

　　3 From energy density division: capacity type, power type

　　4 Division from electrolyte: liquid lithium ion battery, solid lithium ion battery (polymer)

　　5 From orthopedic data scores: lithium cobaltate (C), lithium manganate (m), ternary lithium (n), lithium phosphate (F) are routinely used in cylindrical 18650 batteries, which is a high diameter of 18mm high 65mm cylindrical battery.

　　Following the widespread use of digital products such as mobile phones, laptops and other products, lithium -ion batteries are widely used in such products with excellent functions, and gradually develop in other products applications. In 1998, Tianjin Power Research Institute began to commercialize lithium -ion batteries. In terms of habits, people also call lithium ion batteries as lithium batteries, but these two batteries are different. Lithium ion batteries have become dry flow.

　　Because the chemical characteristics of lithium metal are very lively, the processing, preservation and application of lithium metal are very high in processing, preservation, and use. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, now lithium batteries have become dry flow

　　Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium -ion batteries do not contain metal lithium, and can be charged.
