What to know about Collective vibrations unlock fast ion flow in superionic crystals

Researchers at the Hong Kong University of Science and Technology have identified a mechanism where collective vibrational dynamics, rather than simple diffusion, drive rapid ion transport in superionic crystals. The study suggests that tuning these vibrations through defect engineering can enhance the efficiency of solid-state batteries and thermoelectric devices.
