Lithium-ion battery

 

Lithium-ion battery characteristics

A. High energy density
The weight of lithium-ion battery is the same Capacity of nickel-cadmium or nickel-metal hydride batteries half, the volume is 40-50% of nickel-cadmium, nickel-hydrogen of 20-30%.

B. High voltage
A lithium-ion cell operating voltage of 3.7V (average), equivalent to three series of nickel-cadmium or nickel metal hydride batteries.

C. No pollution
Lithium-ion batteries do not contain harmful metals such as cadmium, lead and mercury.

D. Does not contain metallic lithium
Lithium-ion batteries contain no metallic lithium and are therefore not subject to the restrictions imposed by aircraft transport on the prohibition of carrying lithium batteries in passenger aircraft.

E. Cycle life is high
Under normal conditions, lithium-ion battery charge-discharge cycle can be more than 500 times.

F. No memory effect
The memory effect refers to the phenomenon that the capacity of the battery is reduced during the charge-discharge cycle of the nickel-cadmium battery, and the lithium ion battery does not have such effect.

G. Fast charging
The use of constant voltage and constant voltage charger with a rated voltage of 4.2V can make the Li-ion battery fully charged in one to two hours.
