7.4v 35C lithium battery is a type of battery that uses a lithium metal or lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. With the development of science and technology, lithium batteries have become the mainstream.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Safety, specific capacity, self-discharge rate and cost performance are better than lithium-ion batteries.
