The main components of lithium-ion batteries

From:CTECHI GROUP Limited     Release time:2020-01-02

Overview:Positive electrode-Active materials mainly refer to lithium cobaltate, lithium manganate, lithium iron phosphate, lithium nickelate, lithium nickel cobalt manganate, etc. The conductive current collector generally uses aluminum foil with a thickness of 10-20 microns

The main components of lithium-ion batteries:

(1) Positive electrode-Active materials mainly refer to lithium cobaltate, lithium manganate, lithium iron phosphate, lithium nickelate, lithium nickel cobalt manganate, etc. The conductive current collector generally uses aluminum foil with a thickness of 10-20 microns;

(2) Diaphragm-a special plastic film that allows lithium ions to pass through, but is an insulator for electronics. At present, there are mainly two kinds of PE and PP and their combinations. There is also a type of inorganic solid diaphragm, such as an alumina diaphragm coating, which is an inorganic solid diaphragm;

(3) Negative electrode-the active material mainly refers to graphite, lithium titanate, or a carbon material with a graphite structure. The conductive current collector generally uses a copper foil with a thickness of 7-15 microns;

(4) Electrolyte-generally an organic system, such as a carbonate solvent in which lithium hexafluorophosphate is dissolved, and some polymer batteries use a gel-like electrolyte;

(5) Battery case-mainly divided into hard case (steel case, aluminum case, nickel-plated iron case, etc.) and soft case (aluminum plastic film).
