[SMM Analysis] 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 design that ingeniously uses the entire tail of the current collector as the tab. Through the cover plate (current collector plate) structure design, the tab conduction area and the connection area at the connection point are increased, and the tab conduction distance 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 superfast charging performance at a 5C charge/discharge rate, achieving 80% SOC superfast charging in 10 minutes.
