High energy density
Lithium-ion batteries weigh half as much as nickel-cadmium or nickel-hydrogen batteries of the same capacity. The volume of lithium-ion batteries is 20-30% of nickel-cadmium batteries and 35-50% of nickel-hydrogen batteries.
high voltage
The working voltage of a single lithium-ion battery is 3.7V (average), which is equivalent to three series nickel-cadmium or nickel-hydrogen batteries.
Pollution-free
Lithium-ion batteries do not contain harmful metals such as cadmium, lead and mercury.
Non-metallic lithium
Lithium-ion batteries do not contain lithium metal, so they are not subject to restrictions on the prohibition of carrying lithium batteries on passenger aircraft.
High cycle life
Under normal conditions, the charging and discharging cycles of lithium ion batteries can exceed 500 cycles, and lithium ferrophosphate (hereinafter referred to as ferrophosphorus) can reach 2000 cycles.
Memoryless effect
Memory effect refers to the phenomenon that the capacity of nickel-cadmium batteries decreases during charging and discharging cycles. This effect does not exist in lithium-ion batteries.
Fast Charging
Using a constant current and constant voltage charger with rated voltage of 4.2V, lithium-ion batteries can be charged in 1.5-2.5 hours, while newly developed lithium-iron-phosphate batteries can be charged in 35 minutes.
