NiMH and Li-ion are both suitable to be used as EV battery. 2. Li-ion battery is better than NiMH when it is used as battery of Pure electric vehicle, since it has higher energy density than NiMH. 3. Two kinds of battery are too expensive to be commercial used in electric vehicle. Li-ion battery is more expensive than NiMH battery 4. Both two kinds of battery need management system to ensure their safety. 5. The uniformity of batteries in one pack is very important. 收起
