"Lithium battery" refers to a battery made of lithium metal or lithium alloy as a negative electrode material, using a non-aqueous electrolyte solution.It has a high energy density.Compared with high-capacity nickel-cadmium batteries, the energy density is twice as high.High voltage. The average service voltage is 3.6v, which is three times higher than nickel-cadmium and nickel-hydride batteries.The use voltage is even and the high capacity, the widespread use temperature -20 degrees -60 degrees, the charge and discharge life is long, after 500 discharges its capacity at least has more than 70%.Due to the characteristics of high energy density, high voltage and stable operation, lithium battery is widely used.
