What is a full-tab battery cell? How is the progress of enterprises? A full-tab battery cell (also known as a tabless design) refers to a clever structural design that directly uses the entire tail of the current collector as the tab. By designing the cover plate (current collector plate) structure, the conduction area of the tab and the connection area at its junction are increased, and the conduction distance of the tab is shortened. The internal resistance of a full-tab battery is reduced by approximately 70% compared to traditional batteries, the high-current discharge temperature is reduced by 35%, and the cycle life is improved by 100% compared to traditional batteries. It also supports continuous discharge at a maximum current of 100A, pulse discharge at 200A, and the extremely low internal resistance supports the battery's 5C superfast charging performance, achieving 80% SOC superfast charging in 10 minutes.
