1. High Energy DensityThe weight of a lithium ion battery is approximately one half compared to a nickel-cadmium or nickel-metal hydride battery of similar capacity. Moreover, the volume of the lithium ion battery is 40 to 50% smaller than that of a nickel-cadmium and 20 to 30% smaller than that of a nickel-metal hydride battery. 2. High VoltageA single lithium ion cell has a voltage of 3.7V (mean value), which is equal to either three nickel-cadmium or nickel-metal hydride cells connected in series.3.Good safety performance As the aluminum bluster outer package is different from the meta shell of liquid lithium ion battery, and once safety problems arise, there is no explosion but only expansion. 4. Pollution-freeThe lithium ion battery does not contain any polluting substances such as cadmium, lead, mercury, etc.5. Non-metal LithiumThe lithium ion battery does not employ any lithium metal. It is not governed by aircraft transportation rules relating to carrying lithium batteries in passenger airplanes.6. Long Cycle LifeUnder normal conditions, the lithium ion battery has a life of more than 500 charge/discharge cycles.7. No Memory EffectThe lithium ion battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.8. Fast Charge CapacityThe lithium ion battery can be fully charged in 1 to 2 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charger with a rated voltage of 4.2V per cell.
