What are the reasons for the popularity of lithium batteries

The batteries have 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 ones. If the customer requires the voltage of the battery to be used, it is easy to form a battery pack, and it is convenient and quick to increase the voltage of the battery.
 
The energy and density of lithium-ion batteries are also high compare to other types. Lithium-ion batteries have a high energy storage density. Currently commonly used batteries have a density of 450-620Wh/kg, which is 5-7 times that of lead-acid ones. If people choose batteries, they will also consider a very important issue, that is, pollution.
 
Compare the its weight. The weight is about 5-6 times that of a lead-acid battery. Although the weight of batteries and polymer  batteries are not much different. But looking at capacity and life, people will choose lithium-ion ones.
 
Lithium-ion batteries have a long service life. It can be used for more than 6 years, as long as 9 years, if no accident occurs. The normal use frequency is more than 1000 times. If there are no accidents, the number of uses can reach more than 1500.
 
Low self-discharge and no memory effect. In the production of 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 chargeable batteries used in electric vehicles can achieve high-efficiency charging and discharging at 15-30C, so that the high-intensity start-up and acceleration of the car can be accelerated.
 
The batteries are green and environmentally friendly. They do not contain lead, mercury, and cadmium toxic substances.
