Lithium-ion battery is the name given to a class of rechargeable cells that use lithium inter-calation reaction in both electrodes;lithium ions reavel between the two electrodes in a so-called rocking chair framework.
Among Li-ion cells,lithium polymer(LiPo) cells uise a polymer or gel electrolyte, while all other cells use a nonaqueous,liquid electrolyte.
Many Li-ion chemistries are avaiable.They are usually named according to the composition of the cathode. They include:
*LiMnNiCo: Lithium manganese-nickel cobalt;
*LiFePO4 and Li2FePO4F:Nano-phophate/lithium-iron-phosphate/lithium-rro-phosphate;
