Why is polymer battery good?

1. Polymer lithium ion battery has high voltage and light weight. The average voltage of a single battery can reach 3.7V or 3.2V. It is relatively equal to the series voltage of 2-4 nickel-hydrogen batteries or nickel-isolated batteries. If the customer requires the voltage of the battery to be used, it is easy and convenient to form a lithium-ion battery pack by choosing a lithium-ion battery, which is convenient and quick to increase the voltage of the lithium-ion battery. 2. The energy and density of lithium-ion batteries are also high for other batteries. Lithium-ion batteries have a high energy storage density. Currently commonly used lithium-ion batteries have a density of 450-620Wh/kg, which is 5-7 times that of lead-acid batteries. 3. If people choose a battery, they will also consider a very important issue, that is, pollution. The polymer lithium ion battery is green and environmentally friendly, and the battery does not contain lead, mercury, and cadmium toxic substances. 4. Compare the battery weight. The weight of a lithium-ion battery is about 5-6 times that of a lead-acid battery. Although the weight of lithium-ion batteries and the weight of polymer lithium-ion batteries are not much different. But looking at capacity and life, people will choose lithium-ion batteries. 5. The service life of lithium-ion battery is very long. If there is no accident, the service life of a lithium-ion battery can be used for more than 6 years, up to 9 years. The normal number of uses is more than 1000 times. If there are no accidents, the number of uses can reach more than 1500. 6. The polymer lithium ion battery has low self-discharge and no memory effect. In the production of lithium-ion batteries, adding a protective plate to the lithium-ion battery can make the lithium-ion battery have an overcharge and overdischarge effect. Lithium-ion batteries have high power endurance. The lithium-ion batteries used in electric vehicles can reach a high-efficiency charge and discharge capacity of 15-30C, so that the high-intensity start-up and acceleration of the vehicle can be achieved.
