A. 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 40-50% of nickel-cadmium and 20-30% of nickel-hydrogen.
B. 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.
C. No pollution
Lithium-ion batteries do not contain harmful metal substances such as cadmium, lead, and mercury.
D. No metal lithium
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.
E. High cycle life
Under normal conditions, the charge and discharge cycle of a lithium ion battery can exceed 500 times.
F. 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.
G. Fast charging
A constant current constant voltage charger with a rated voltage of 4.2V can be used to fully charge a lithium ion battery in one to two hours.
