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.
