Classification of lithium-ion batteries for Electric Bicycles

2023-07-03

According to different Technology roadmap, lithium-ion batteries for E Bike mainly include Lithium iron phosphate, lithium manganate and ternary lithium batteries.

The biggest advantage of Lithium iron phosphate battery is its good safety, which is mainly reflected in its high Autoignition temperature, which requires more than 500-800 degrees Celsius before self ignition or explosion. Therefore, in case of accidents, only ash smoke is often emitted, and open fire is rarely seen. The Lithium iron phosphate battery has a long cycle life. It can be charged and discharged more than 2000 times in general applications, but its low temperature performance is poor. In winter, the power failure is severe, and the service mileage is significantly shortened.

In addition, the energy density is relatively lower compared to ternary Lithium Battery. At the same battery energy, the volume and weight are about twice that of ternary lithium batteries, so the application proportion in Electric Bicycle is relatively small; However, due to the good safety performance of Lithium iron phosphate battery, there is a trend of increasing application proportion.

The main advantage of ternary lithium batteries lies in their high energy density, making them a "new gem" in the field of Ebikes. Their drawbacks are also quite fatal: poor safety, and they are prone to combustion and explosion after short circuits.

The application of ternary Lithium Batteries in Electric City Bike is relatively limited, but due to the early use of ternary lithium batteries in electric vehicle power batteries
