(1) Lithium ion battery has high voltage and light weight. The average voltage of a single battery can reach 3.7V or 3.2V, which is relatively equal to the series voltage of 2-4 nickel metal hydride batteries or nickel interval batteries. If the customer requires the battery voltage to pass, the choice of lithium-ion battery is also easy to form a lithium-ion battery pack, which can easily and quickly increase the voltage of the lithium-ion battery

(2) Lithium ion batteries of other batteries also have high energy and density. Lithium ion battery has high energy storage density. At present, the density of commonly used lithium-ion batteries can reach 450-620whkg, 5-7 times that of lead-acid batteries. If people choose batteries, they will also consider a very important issue: pollution

(3) Comparison of battery weight. Lithium ion batteries weigh about 5-6 times as much as lead-acid batteries. Although the weight of lithium ion battery is not different from that of polymer lithium ion battery. But in terms of capacity and service life, people will choose lithium ion batteries.

(4) If there is no accident, the lithium-ion battery can be used for more than 6 years, up to 9 years. The number of normal uses exceeds 1000. If there is no accident, it can be used more than 1500 times

(5) Low self discharge, no memory effect. In the production of lithium-ion battery, adding a protective plate on the lithium-ion battery can make the lithium-ion battery overcharge and discharge. Lithium ion battery itself has high power carrying capacity. The lithium-ion battery selected for electric vehicles can achieve the high efficiency response capability of 15-30c charging and discharging, which is convenient for high-intensity starting and acceleration of vehicles.
