Main characteristics of lithium ion battery
Jul 28,2022
A. The weight of high energy density lithium ion battery is half of that of nickel cadmium or nickel hydrogen battery with the same capacity, and the volume is 20-30% of nickel cadmium and 35-50% of nickel hydrogen.
B. High voltage The working voltage of a single lithium-ion battery is 3.7V (average), which is equivalent to three nickel-cadmium or nickel-hydrogen batteries in series.
C. Non-polluting lithium-ion batteries do not contain harmful metal substances such as cadmium, lead and mercury.
D. The lithium-ion battery without metal lithium does not contain metal lithium, so it is not subject to the provisions of aircraft transportation on the prohibition of carrying lithium batteries in passenger aircraft. E. High cycle life Under normal conditions, the charge and discharge cycle of lithium ion battery can exceed 500 times, and the lithium ferrous phosphate (hereinafter referred to as ferrophosphate) can reach 1000 times.
F. Memory effect without memory effect refers to the phenomenon that the capacity of Ni-Cd battery decreases during the charge-discharge cycle. Lithium ion batteries do not have this effect.
G. The constant current and constant voltage charger with rated voltage of 4.2V is used for fast charging, which can make the lithium ion battery fully charged within 1.5-2.5 hours; The newly developed lithium phosphate battery can be fully charged in 35 minutes.
