Researchers at Tokyo Institute of Technology and other institutions have recently developed an all-solid-state battery that can be super-high-speed charge and discharge, making a big step toward the practical application of all-solid-state batteries.
The all-solid lithium battery is a new type of battery using solid electrodes and solid electrolytes. Its high density, high safety, high output power and other performance are superior to traditional liquid batteries, and it has broad application prospects in the field of new energy vehicles. It is expected to replace the next generation of lithium-ion batteries.
Although many countries around the world are competing to develop all-solid-state batteries, their practical application faces a big problem: There is a high resistance at the interface between the high-voltage electrode and the solid electrolyte, which affects the battery performance. So far, there is no clear solution.
Researchers at the Tokyo Institute of Technology collaborated with colleagues from the National University of Technology, Tohoku University, and other institutions. They improved lithium electrode materials, reduced interface resistance to extremely low levels, and successfully achieved ultra-high-speed charging of all-solid-state batteries. Discharge.
