Batteries with self-repairing capabilities: or will be used in electric vehicles
2022-03-10
According to news on November 19, in the race to develop better quality batteries, scientists regard silicon as a suitable material because it can maintain abundant energy while charging. But this material also has an obvious defect, that is, it will expand and cause rupture during charging, making it unusable. However, scientists in the SLAC laboratory of Stanford University have recently developed a silicon electrode with self-healing ability to solve this problem.
It is reported that the researcher's invention was inspired by the latest research on robot skin. They created a silicon polymer with weak chemical bonds. When the material breaks, they attract each other, which can be reshaped within a few hours.
By using this material, the research team achieved 100 discharge cycles, which is a very good result. The team said that this is just the beginning, and their goal is to eventually reach 3000 discharge cycles, so as to achieve the use of electric vehicles.
