The development of lithium-ion battery and its additive were reviewed
according to their functions
the additives can be divided into these categories:SEI forming improver additives
overcharge protection additives
improve low-temperature performance additives
thermal stability of electrolyte improvement additives
and so on.Each group has been discussed in terms of electrochemical mechanisms.The prospect of the additives used in non-aqueous electrolyte in the future was predicted.
