Abstract:  With the energy crisis and environment pollution occurring, energy saving and environmentally friendly electric vehicles (EVs) will gradually be developed in the future. As one of the most important parts of EVs, power batteries are facing various challenges in technology. This paper describes the current state of EV battery industry and the six factors concerned by the EV lithium-ion battery market, including the safety, life span, specific energy, specific power, charging time and cost, which are used to expect the battery technology, cost and market. The results show that battery commoditization will soon be achieved in terms of the current rates of innovation in battery performance and decrease in cost.

Key words: electric vehicle (EV), lithium-ion battery, battery performance, cost, market, ecosystems
