April 6th report: According to media sources, at the recent Second Sodium Battery Industry Summit, Zhang Jian, the product line director of Fudi Battery, stated that BYD is expected to conduct a comprehensive application scenario trial of large cylindrical sodium-ion batteries for electric two-wheelers in Shenzhen in June.
Zhang Jian explained that BYD's sodium battery products have passed tests such as short circuit, overcharge, impact, and puncture. The storage performance in some high-temperature scenarios is also excellent, with good rate performance at room temperature and low temperature.
Currently, electric two-wheelers typically use lead-acid batteries, graphene batteries, and lithium batteries. Once lithium batteries catch fire, they burn rapidly and with tremendous force.
In the field of electric two-wheelers, sodium-ion batteries have become a new development direction for the industry. Compared to lithium batteries, sodium-ion batteries have higher internal resistance, less instantaneous heat generation, and lower temperature rise in the event of a short circuit.
In February of this year, a fire caused by an electric two-wheeler in a community in Nanjing attracted widespread attention. At that time, Fudi Battery, a subsidiary of BYD, announced that it would apply the research and development achievements of passenger cars to the two-wheeler field, increasing research and development investment to develop safe batteries that can be used upstairs.
