KAIST boosts low-cost solid-state battery performance 2 to 4 fold
KAIST said on Jan. 7 it developed a design method that improves solid-state battery performance by 2 to 4 times using low-cost raw materials. The team introduced divalent anions such as oxygen and sulfur into zirconium-based halide solid electrolytes to adjust internal structures, widening lithium-ion pathways and lowering barriers. Measured room-temperature ionic conductivity was about 1.78 mS/cm with oxygen and 1.01 mS/cm with sulfur. The study was published in Nature Communications.
