1). Working voltage of single cell can reach 3.6-3.8V
2). High energy rate. At the moment, the energy rate of li-ion battery is 100-115Wh/kg and 240-253Wh/L, which is twice compared with Ni-Cd, 1.5 times to Ni-MH battery. With the technical development, the energy rate of li-ion could reach 150Wh/Kg and 400 Wh/L.
3). Long cycle life, basically speaking, the cycle life of li-ion battery could reach 500-1000 times. For small discharge device, the using time will strengthen the electric device’s competitive power.
4). Safe performance, no pollution, no memory effect.
5). Low self-discharge: Under room temperature, fully charged li-ion battery could be stored with the self-discharge rate of around 10% after one month, which is far lower than Ni-Cd(25-30%), Ni、MH(30-35%).
