What are some characteristics of various types of power batteries?

1. Lead-acid batteries are gradually introduced to the market due to their own performance that limits the development of power sources and lead pollution; 2. Nickel-cadmium batteries also have pot pollution and have serious memory benefits, and the power lithium battery market is basically introduced; 3. Ni-MH batteries It is an improvement of the nickel-cadmium battery, the specific energy can reach 60-80Wh/kg, and it has the characteristics of fast charging speed, basically no memory effect, no environmental pollution, and high safety. At present, the production technology of automobile power lithium battery is basically mature. 4. At present, in the power lithium battery industry, nickel-metal hydride batteries dominate, while lithium iron phosphate batteries are in the early stages of industrial development. 5. Better battery performance (especially safety) and mature manufacturing technology are nickel-hydrogen batteries, which currently dominate the world's ordinary hybrid electric vehicle (HEV) batteries. 6. Ni-MH power lithium batteries currently dominate. The important thing is that the battery energy of existing hybrid vehicles is only 1 to 2kWh, which can not be driven by pure electric or the battery life is less than 3km. In the longer term, NiMH cannot be applied to PHEV and EV. Important because: the specific energy and energy density of Ni-MH cannot meet the requirements of PHEV and EV; the price of raw material Ni (OH) is higher, and the cost of manufacturing large-energy batteries will be higher; the development of nickel-hydrogen battery technology is basically mature, and the battery performance The room for improvement and cost reduction is very limited. 7. Compared with nickel-metal hydride batteries, the advantages of lithium-ion batteries are mainly reflected in: high specific energy and energy density, about twice that of nickel-metal hydride batteries, which can greatly improve the endurance of electric vehicles. Higher power, low self-discharge, and no The memory effect, these characteristics can improve the convenience of using electric vehicles; the cost of raw materials is low; there is a lot of room for technological improvement and a lot of room for cost reduction.
