What are the battery characteristics of lithium batteries?

- Aug 04, 2019-

1 High energy density

The weight of a lithium-ion battery is half that of a nickel-cadmium or nickel-hydrogen battery of the same capacity, and the volume is 20-30% of nickel-cadmium and 35-50% of nickel-hydrogen.

2 high voltage

A lithium-ion battery cell operates at 3.7V (average), which is equivalent to three nickel-cadmium or nickel-hydrogen batteries connected in series.

3 No pollution

Lithium-ion batteries do not contain harmful metal substances such as cadmium, lead, and mercury.

4 Metal lithium free

Lithium-ion batteries do not contain metal lithium, and thus are not subject to the restrictions imposed by aircraft on the prohibition of carrying lithium batteries in passenger aircraft.

5 High cycle life

Under normal conditions, the charge and discharge cycle of a lithium ion battery can exceed 500 times, and lithium iron phosphate (hereinafter referred to as ferrophosphorus) can reach 2000 times.

6 No memory effect

The memory effect refers to the phenomenon that the capacity of the battery decreases during the charging and discharging cycle of the nickel-cadmium battery. Lithium-ion batteries do not have this effect.

7 fast charging

Using a constant-current constant-voltage charger with a rated voltage of 4.2V, the lithium-ion battery can be fully charged in 1.5-2.5 hours; and the newly developed ferrophosphorus lithium battery can be fully charged in 35 minutes.
