What are the power batteries?lithium battery for solar energy storage system company

1. Due to its own performance, lead -acid batteries limited the development of power power supply and had lead pollution, and gradually launched the market;

2. Nickel -cadmium batteries also have pot pollution, with serious memory benefits, and basically launching the power battery market;

3. Nickel-hydride battery is a improvement of nickel-cadmium batteries. It can reach 60-80Wh/Kg than energy, and has the characteristics of fast charging speed, basically no memory effect, no environmental pollution, high safety. Technology is basically mature.

4. At present, in the power battery industry, nickel -metal hydride batteries dominate, while lithium iron phosphate batteries are in the early stages of industrial development.

5. Good battery performance (especially safety) and mature manufacturing technology are nickel -metal hydride batteries. It is currently dominant in the global general hybrid vehicle (HEV) battery.

6. The current dominant position of nickel -metal hydride battery is mainly because the battery energy of the existing hybrid vehicle is only 1 to 2kWh. It cannot be exercised for pure electric or pure electric battery life below 3km. In the long run, nickel -ide cannot be applied to PHEV and EV. mainly because:

· The ratio of nickel -hydride energy and energy density cannot meet the requirements of PHEV, EV;

· Raw material NI (OH), the price is higher, and the cost of manufacturing large energy will be higher;

· The development of nickel -metal hydride battery technology is basically mature, and the space for improvement of battery performance and reduction in cost is very limited.

7. Compared with nickel -hydride batteries, the advantages of lithium -ion batteries are mainly reflected in:· High -energy and energy density is more than twice the nickel -metalized battery, which can greatly improve the battery life of electric vehicles. The power is higher, the self -discharge is small, and the memoryless effect can be improved. These characteristics can improve the convenience of electric vehicles;

· The cost of raw materials is low;
