Lithium battery "middle state" technology can shorten the charging time

A famous academic journal recently published an article stating that new progress has been made in the research on the "intermediate state" structure and transmission characteristics in lithium iron phosphate (LiFePO4) lithium batteries. Researchers at two universities in Tokyo University and Tokyo Institute of Technology said the results of the study will help speed up the response speed of lithium batteries and significantly shorten the battery charging time.

A team led by Atsuo Yamada, a professor at the University of Tokyo's Institute of Engineering, found that the electrons surround the stripe-shaped thin film layer without interrupting the lithium ions and the striped thin film layer. In addition, the "intermediate" lithium / electron conductivity is higher and lithium ions and electrons move faster than the charge or discharge states. At present, the team has succeeded in stabilizing the "intermediate" content at 100%, which is conducive to improving the electrical conductivity. Through the new research program, can quickly charge the battery development will usher in a new breakthrough.
