The energy of lithium-ion batteries for electric vehicles is more than double that of lead-acid batteries. At present, electric bicycles with lead-acid batteries can travel 50~70km once charged and 100~150km with lithium-ion batteries of the same weight. The number of charges and discharges is also high.

●Lithium-ion battery electric bicycles have long life, lightweight, and small size advantages. There is a small-sized lithium-ion battery electric bicycle, which weighs only about 16 kilograms. The battery is only the size of a book and weighs only 2.5 kilograms. It can be carried in a bag and can also be used to charge a computer. The equivalent lead-acid battery weighs about 15 kg.

●The most significant advantage of lithium-ion battery electric bicycles is long life. A set of batteries can be used for 4 to 5 years, while the life of lead-acid batteries is only about two years.

●The lithium-ion battery is easy to activate, as long as 3-5 regular charge-discharge cycles can be used to activate the battery and restore the standard capacity. Due to the characteristics of the lithium-ion battery itself, it has almost no memory effect. Therefore, the user does not need unique methods and equipment during the activation process of the new lithium-ion battery.

Disadvantages of lithium-ion batteries for electric bicycles

●The disadvantage of lithium-ion batteries is that the price is high, and the market share is only 4%. At present, the cost of lithium-ion battery electric bicycles is generally several hundred yuan to one thousand yuan higher than that of lead-acid battery electric vehicles, so the sales volume is not significant.

●Li-ion battery has not been used in electric bicycle products for a long time, and their technology has not reached a high level. Therefore, there are still many technical problems that restrict the development of the electric bicycle lithium-ion battery industry to a certain extent.

●The main problem to be solved by lithium-ion batteries for electric bicycles is the safety problem during use. How to solve the safety problem has become a trend in the development of lithium-ion batteries for electric bikes in the future.
