1. High energy density: the weight of lithium-ion battery is half of nickel cadmium or nickel hydrogen battery with the same capacity, the volume is 20-30% of nickel cadmium and 40-50% of nickel hydrogen.
2. High voltage: the working voltage of a single lithium-ion battery is 3.7V (average value), which is equivalent to three series nickel cadmium or nickel hydrogen batteries.
3. No pollution (environmental protection), lithium-ion battery does not contain heavy metal elements such as cadmium, lead, mercury, etc.
