Battery Features:

  • The specific energy is large. The actual specific energy that can be achieved at present is 100-115Wh/kg and 240-253Wh/L
  • The cycle life is long, generally up to 500 times or even 1000 times.
  • Good safety performance, no pollution, no memory effect. As the predecessor of Li-ion, the lithium battery is prone to short circuit of dendrites due to metal lithium, which reduces its application fields: Li-ion does not contain cadmium, lead, mercury and other elements that pollute the environment.
  • The self-discharge is small, and the self-discharge rate of Li-ion fully charged at room temperature for one year is about 10%
