The application of batteries in 2-3 wheelers mainly includes lead-acid batteries, lithium batteries (including lithium iron phosphate batteries and ternary lithium batteries) and sodium-ion batteries.

Lead-acid battery

Lead-acid batteries are one of the most common battery types in 2-3 wheelers. It uses lead and its oxide as the electrode material and sulfuric acid solution as the electrolyte. Lead-acid batteries are safer because their electrode materials and electrolytes are non-flammable and less likely to cause fires, even at high temperatures or under overcharge. In addition, lead-acid batteries have a high recovery rate and are environmentally friendly. However, the self-discharge characteristics of lead-acid batteries are strong, and the performance will be degraded at low temperatures.

Lithium battery

 Lithium batteries mainly include lithium iron phosphate batteries and ternary lithium batteries. ‌ lithium iron phosphate battery ‌ is famous for its high stability and long cycle life (more than 2000 times), suitable for use in low temperature environment, and high safety, non-flammable ‌23. ‌ terpolymer lithium battery ‌ is characterized by its high energy density and good low temperature performance, but the thermal stability is poor, easy to occur at high temperatures thermal runaway, there are certain safety hazards.

Sodium ion battery 

Sodium-ion battery is an emerging battery technology with high safety and long service life. Although there are few applications on the market at present, its potential is great, especially in the security aspect ‌
