At the recent 5th EV Two-Wheeler Battery Swapping Conference in Shenzhen, BAK Battery showcased its cutting-edge large cylindrical battery solutions designed specifically for the light electric vehicle market. Teng Xiaobo, the company's Cell Technology Director, delivered a keynote presentation titled "High-Performance Cylindrical Battery Tech for Light Electric Vehicles," outlining how BAK's technological breakthroughs address critical industry challenges.

Revolutionary Full-Tab Technology Redefines Performance Standards

The centerpiece of BAK's innovation is its proprietary full-tab cylindrical cell design. This groundbreaking architecture delivers comprehensive performance improvements:

• ● An 80% reduction in internal resistance significantly improves energy efficiency

• ● Temperature rise decreased by over 80% enhances safety parameters

• ● Multi-fold extension of cycle life improves product longevity

The technology incorporates unique venting mechanisms that enable cells to pass stringent safety tests while maintaining "zero thermal spread" performance. Importantly, these advancements come without cost penalties. Comparative analysis demonstrates that cylindrical cells in the 15-50Ah range offer superior production efficiency, lower manufacturing costs, and better yield rates than prismatic or pouch alternatives.
