Often overlooked, rechargeable batteries play an important part in contemporary life, powering small devices like smartphones to larger ones like electric vehicles. The keys to creating sustainable rechargeable batteries include having them hold their charge longer, giving them a longer life with more charging cycles, and making them safer. Which is why there is so much promise in all-solid-state batteries.

The problem so far is discovering which solid electrolytes offer such potential advantages.

In a step toward that goal, an Osaka Metropolitan University research group led by Assistant Professor Kota Motohashi, Associate Professor Atsushi Sakuda, and Professor Akitoshi Hayashi of the Graduate School of Engineering has developed an electrolyte with high conductivity, formability, and electrochemical stability.
