Stabilizing electrode/electrolyte interfaces in solid-state batteries
ISN-affiliated MIT researchers led by Dr. Bilge Yildiz, working with personnel from Brookhaven National Laboratory, have achieved a significant advance in the development of solid-state batteries resulting from a new and simple method for stabilizing their electrode/electrolyte interfaces. Ultimately, it may result in much safer batteries that store twice as much energy.

These discs were used for testing the researchers’ processing method for solid-electrolyte batteries. On the left, a sample of the solid electrolyte itself, a material known as LLPO. At center, the same material coated with the cathode material used in their tests. At right, the LLPO material with a coating of gold, used to facilitate measuring its electrical properties.
