Batteries, as the core component of the new-energy vehicle (NEV), play an important role in the development of NEV. Considering the development tendency of NEV, we raise a possible development route for the batteries in NEV, which is Nickel-metal hydride battery, Lithium ion battery, All solid state battery, Fuel cell and Lithium air battery. The current states of the above batteries are analyzed based on the overall arrangement of major vehicle companies in NEV field. We focus on the problems occurred in the development process of the batteries, and try to give some solutions for these problems or predict the improvement direction. Finally, we compare the advantages and disadvantages of these batteries, and then forecast the key point and research orientation of batteries in NEV in the next 10 years.
