Lithium-ion batteries - features
A. High energy density
Lithium-ion batteries weigh half as much as nickel-cadmium or nickel-metal hydride batteries of the same capacity, and their volume is 40-50% that of nickel-cadmium and 20-30% that of nickel-metal hydride.
B. High voltage
The operating voltage of a single lithium-ion battery cell is 3.7V (average value), which is equivalent to three nickel-cadmium or nickel-metal hydride batteries connected in series.
C. Pollution-free
Lithium-ion batteries do not contain harmful metals such as cadmium, lead, and mercury.
D. Contains no metallic lithium
Lithium-ion batteries do not contain metallic lithium, therefore they are not subject to regulations prohibiting the carrying of lithium-ion batteries on passenger aircraft.
E. High cycle life
Under normal conditions, lithium-ion batteries can have more than 500 charge-discharge cycles.
F. Memoryless effect
The memory effect refers to the reduction in capacity of nickel-cadmium batteries during charge-discharge cycles. Lithium-ion batteries do not exhibit this effect.
G. Fast charging
A constant current and constant voltage charger with a rated voltage of 4.2V can fully charge a lithium-ion battery in one to two hours.
