Liquid-Like Molecular Dynamics Power Solid Battery Materials
Researchers at Duke University have uncovered the molecular behavior of a lithium-based solid electrolyte material, which could be key to next-generation rechargeable batteries. Unlike conventional lithium-ion batteries, which use liquid electrolytes, this solid-state material allows lithium ions to move quickly through its rigid crystalline structure, behaving like a liquid at the atomic level. By using neutron scattering and computational models, the team discovered that molecular vibrations in the material facilitate the rapid ion movement, offering insights into designing safer, more efficient solid-state batteries. These findings could lead to cheaper, sodium-based alternatives, addressing challenges like lithium scarcity and high costs.
