The PRC is the world’s largest producer, consumer and exporter of electric bikes. According to the “2025 Consumer Goods Industry Series Research Report — Interpretation of the New National Standard for Electric Bicycles” published by the China Electronics Standardisation Institute, electric bike ownership in the PRC has reached an estimated 350 million units. In addition, the 2025 China Two-Wheel Electric Vehicle Industry Research Report suggests that China’s annual sales of two-wheel electric vehicles reach around 52 million units in 2025. With the gradual implementation of the “New National Standards” in provinces and cities across the PRC, coupled with the release of the “Implementation Plan for the Promotion of Electric Bicycles Trade-in”, the demand for electric bicycle replacements has been consistently stimulated.

The key components of a lead-acid motive battery include electrode plates and fiber glass dividing plates. The number and the size of electrode plates required to be installed in a lead-acid motive battery will depend on the required level of its storage capacity and power output. The electrode plates are coated with oxidized lead and alloy lead. Pairs of positively charged electrode plates and negatively charged electrode plates each separated by a fiber glass dividing plate are bound together by metal strips and installed into the plastic casing of a lead-acid motive battery. The battery is then filled with sulphuric acid and charged with electricity.
