The weight of a high-energy density lithium-ion battery is half that of a nickel-cadmium or nickel-metal hydride battery of the same capacity, and the volume is 20-30% of nickel-cadmium and 35-50% of nickel-metal hydride.
The operating voltage of a lithium-ion battery monomer at high voltage is 3.7V (the average), which is equivalent to three nickel-cadmium or nickel-metal hydride batteries connected in series.
Non-polluting lithium-ion batteries do not contain harmful metals such as cadmium, lead, mercury and so on.
Lithium-free lithium-ion batteries do not contain metal lithium and are therefore not subject to the restrictions on aircraft carriage that prohibit the carriage of lithium batteries on passenger aircraft.
Under normal conditions, the charge and discharge cycle of lithium-ion batteries can exceed 500 times, and lithium ferrous phosphate can reach 2000 times.
The memory-free effect memory effect refers to the phenomenon that the capacity of the battery decreases during the charge-discharge cycle of nickel-cadmium batteries. Lithium-ion batteries do not have this effect.
Fast charging uses a constant current and constant voltage charger with a rated voltage of 4.2V, which can make the lithium-ion battery fully charged in 1.5-2.5 hours; and the newly developed lithium phosphorus iron battery can already be fully charged in 35 minutes.
