On November 19, at the "Green Travel, Smart Transportation"-2020 China Bicycle Industry Conference, the China Bicycle Association released the first "White Paper on Safety of Lithium-ion Battery for Electric Bicycles." The white paper is divided into six chapters, which comprehensively discuss the design and manufacture of lithium-ion batteries from the aspects of lithium-ion battery, lithium-ion battery charging and discharging mechanism, lithium-ion battery thermal runaway mechanism, safety prevention and control mechanism, corporate specifications, and application specifications. And matters needing attention in use.

According to data from the China Bicycle Association, in the past ten years, the annual sales volume of electric bicycles in my country has exceeded 30 million, and the social ownership will reach 300 million by the end of 2020. However, in the process of using electric bicycles, there are still situations that can easily cause safety accidents such as long-term charging, charging with inferior chargers, and private modification.

According to the China Bicycle Association, electric bicycles use batteries as auxiliary energy sources, and batteries are currently mainly divided into lead-acid batteries and lithium-ion batteries. As the country continues to regulate the standards of the electric vehicle industry, and the lithium-ion battery itself has the advantages of high energy density, high voltage, long life, wide working range, and no heavy metal pollution, more and more companies have begun to choose lithium-ion batteries as Auxiliary energy for electric bicycles.

At present, under the dual influence of the new national standard for electric bicycles and the market "replacement tide", the penetration rate of lithium-ion batteries in the electric bicycle market is accelerating.

Due to the lack of safety research and related standards on lithium-ion batteries for electric bicycles in the electric bicycle industry, enterprises, dealers, consumers, and operation and maintenance points are lacking in the popularization of lithium battery safety knowledge, which is caused by the abuse and improper application of lithium batteries. Safety accidents occur from time to time, which has also become one of the factors hindering the continued development of lithium batteries in the field of electric bicycles.

The release of the "White Paper on the Safe Use of Lithium Ion Batteries for Electric Bicycles" is expected to guide and promote the development of the safe application of lithium batteries in the electric bicycle industry. The China Bicycle Association also hopes that the release of this white paper can guide the development of the industry.
