A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.  Li-ion battery is mainly composed of positive electrode, negative electrode, electrolyte and diaphragm. Chemistry, performance, cost and safety characteristics vary across LIB types. Electrolytes are all liquid. The biggest difference for various Li-ion battery…
