Batteries is one of the main systems of electric vehicle. Batteries determine the total performance and define the capabilities of the electric vehicle regardless it is a passenger vehicle or heavy truck. Batteries are also determining the total price of the electric vehicle to large extend. In this report we are focusing on the technology development in historic perspective of the last 15 years in China. We see that the lithium-ion technology is the dominant technology, but we also see new emerging battery technologies that might be the game changer for the performance of electric vehicles. We demonstrate the dynamics of main battery technologies, LFP (lithium iron manganese, LiFeO4, battery cell) battery and NMC (lithium nickel manganese cobalt oxide battery cell) battery, the distribution of installed volumes between LFP and NMC in the Chinese market.
