Toronto: Scientists, including one of Indian origin, have developed a button-sized, garnet-based rechargeable battery that may power vehicles, electronics and grids for storing renewable energy. Current lithium-ion batteries have several issues, including leakage, poor chemical stability, flammability and limited operating voltage or energy density. “The technology we have developed would enable absolutely stable, robust, safe, high-powered, all solid-state lithium batteries for future energy storage,” said Thangadurai. Instead of organic polymers for their battery, researchers used a solid ceramic electrolyte, which does not burn. With their chemically engineered, garnet-based, ceramic electrolyte, the team showed there was “negligible interface resistance” between the lithium metal anode and the ceramic electrolyte interface.
