Abstract: Extended-Range Electric Vehicle (E-REV) is a new type of electric vehicle in which a range extender (RE) extends the range by charging the battery or directly drive the electric motor. It is a transition mode of the Hybrid Electric Vehicle (HEV) and the Electrical Vehicle (EV). Comparing with HEV, it has advantage in lowing the emission, noise and systematic complexity. While comparing with EV, it has advantage in longer range and lower cost. Thus, E-REVs is a promising mode for large scale commercial applications. The batteries in E-REVs do not need to support very long range by themselves, but they need higher efficiency, higher energy density and higher power density. This is a new challenge and opportunity for lithium-ion battery development. This paper briefly introduces the development of E-REVs and their high importance to the new energy vehicle development of our nation. Base on this, the batteries suitable for E-REVs are also reviewed.

Key words: extended-range electric vehicle, lithium-ion battery, power density, energy density, electrode materials
