Safe and Efficient Energy: Game-Changing Battery Materials Discovered

Researchers have discovered a pyrochlore-type oxyfluoride as a stable, lithium-ion conductor with excellent conductivity, suitable for use as solid electrolytes in all-solid-state lithium-ion batteries. Credit: scalespeeder fromScientists have identified a stable and highly conductive lithium-ion conductor that can be used as solid electrolytes in solid-state lithium-ion batteries.

While sulfide-based solid electrolytes are conductive, they react with moisture to form toxic hydrogen disulfide. Therefore, there’s a need for non-sulfide solid electrolytes that are both conductive and stable in air to make safe, high-performance, and fast-charging solid-state Li-ion batteries., a research team led by Professor Kenjiro Fujimoto, Professor Akihisa Aimi from Tokyo University of Science, and Dr.

Exactly, even at –10°C, the new material has the same conductivity as conventional oxide-based solid electrolytes at room temperature. Furthermore, since conductivity above 100 °C has also been verified, the operating range of this solid electrolyte is –10 °C to 100 °C. Conventional lithium-ion batteries cannot be used at temperatures below freezing. Therefore, the operating conditions of lithium-ion batteries for commonly used mobile phones are 0 °C to 45 °C.

Unlike existing lithium-ion secondary batteries, oxide-based all solid-state batteries have no risk of electrolyte leakage due to damage and no risk of toxic gas generation as with sulfide-based batteries. Therefore, this new innovation is anticipated to lead future research. “The newly discovered material is safe and exhibits higher ionic conductivity than previously reported oxide-based solid electrolytes.
