Because the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. Now, lithium batteries have become the mainstream.

　　Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li+MnO2=LiMnO2, which is an oxidation-reduction reaction. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. Now, lithium batteries have become the mainstream.

　　At present, lithium-ion batteries are commonly used in electric bicycle products, and have solved the problem of light-weight and beautiful product requirements for electric bicycles. However, because of its short application time, the power lithium battery technology has not reached the perfect level. Therefore, there are still many problems to be solved. Below, we will analyze the current technical status of lithium batteries for electric bicycles.
