【Abstract】 With the rapid progress in the development of the Li-ion power batteries, LiFePO4 is expected to be widely used as a new cathode material in Li-ion battery for their many advantages. But its poor performance at low temperature is concerning all the time. In this paper the reasons of the performance at low temperature difficult to improve were introduced and three main components of the Li-ion batteries which affected the performance at low temperature were systematically discussed. Finally, the solution to improve performance at low temperature for cathode material of LiFePO4 was also put forward.更多还原
