1. First, you need to understand the materials. Kaimeiwei's is ternary polymer lithium battery, Chaowei's is lead acid, BYD used iron phosphate, but then changed to ternary polymer
2. High voltage: the working voltage of a single battery can reach 3.7-4.2V (lithium iron phosphate is 3.2V), and ternary polymer is 4.2V.
3. The long life can generally reach more than 500 times, or even more than 1,000 times, and lithium iron phosphate can reach more than 2,000 times. The ternary polymer can reach 2500 cycles
4. No pollution and no memory effect. The new lithium-ion battery has a short circuit because lithium metal easily forms dendrites, which reduces its application areas: Li- Li-. ion does not contain cadmium, lead, mercury and other elements polluting the environment: a major disadvantage ofNi-Cd batteries with certain processes (such as sintered type) is the "memory effect", which seriously restricts the use of batteries, but Li-ion There is no problem in this regard.
5. 1C fast charging can charge to more than 80% of rated capacity in 30 minutes, and ternary polymer batteries can charge to 90% of rated capacity in 10 minutes.
6. Operating temperature The operating temperature is -25 to 45°C. With the improvement of electrolyte and positive electrode, it should be extended to -40 to 70°C.
