Lead-acid batteries
Lead-acid battery as a relatively mature technology, because of low cost, but also high-rate discharge, can be mass. By experts optimistic about the economic field of electric cars market space.
Lead-acid battery specific energy, specific power and energy density are low, use it as a power source for electric vehicles can not have good speed and mileage can be used as low-speed electric cars economical power supply.
NiMH batteries
Although the performance is better than lead-acid batteries, but contain heavy metals, after use can cause pollution to the environment
Currently, Toyota and Honda hybrid car uses battery power started by nickel metal hydride batteries to lithium transition.
Lithium battery
The traditional lead-acid batteries, nickel cadmium batteries and nickel-hydrogen battery technology itself is relatively mature, they are used in car batteries as a power there is a big problem. At present, more and more car manufacturers choose to use lithium batteries as a new energy vehicle power battery.
Lithium iron phosphate as a lithium battery, the specific energy is less than half of lithium cobalt oxide, but safe, cycle times can be up to 2000 times, discharge stability, cheap, become a new choice of car battery.
