Self-repairing batteries could soon become a reality

Engineers at the University of Tokyo have developed a material which could give more life and higher capacities to batteries.

The study was published in the journal Nature Communications.

Atsuo Yamada and his team demonstrated that if the battery is made with a model material – oxygen redox-layered oxide (Na2RuO3) – something remarkable happens. Not only does the degradation from charge and discharge cycles diminish, but the layers actually self-repair.
