What are the characteristics of lithium-ion batteries?

Lithium-ion batteries have the following characteristics: A. The weight of high-energy density lithium-ion batteries is half of the same capacity of nickel-cadmium or nickel-hydrogen batteries, and the volume is 40-50% of nickel-cadmium and 20-30% of nickel-hydrogen. B. High voltage The working voltage of a single lithium-ion battery is 3.7V (average value), which is equivalent to three nickel-cadmium or nickel-hydrogen batteries connected in series. C. Pollution-free lithium ion batteries do not contain harmful metal substances such as cadmium, lead, and mercury. D. Metal-free lithium lithium-ion batteries do not contain metal lithium, so they are not subject to restrictions on the prohibition of carrying lithium-ion batteries on passenger aircraft in aircraft transportation. E. High cycle life. Under normal conditions, the charge-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 nickel-cadmium battery decreases during the charge-discharge cycle. Li-ion batteries do not have this effect. G. Fast charging Use a constant current and constant voltage charger with a rated voltage of 4.2V to fully charge the lithium-ion battery in one to two hours.
