The development of electric bicycle batteries
The earliest use of electric bicycles is lead-acid batteries, because of its low cost, easy to produce, but due to large size, heavy weight, poor endurance, gradually eliminated. Then came nickel-metal hydride batteries, which provided higher energy density and lighter weight, but still had the problem of high self-discharge rate and short cycle life. To address these shortcomings, lithium-ion batteries have gradually become mainstream, significantly improving the performance of electric bicycles with higher energy density, lighter weight and longer service life. However, lithium-ion batteries still face safety risks, such as overheating, fire, and recycling to deal with complex environmental issues, prompting the industry to continue to explore safer and environmentally friendly alternative technologies.
