What's Happening?
A study published in Nature investigates the use of lattice-matched antiperovskite-perovskite systems to enhance the performance of all-solid-state batteries (ASSBs). The research focuses on a composite solid electrolyte utilizing fluorine-doped antiperovskite c-Li2OHCl combined with perovskite LLTO, achieving high lattice matching and optimal interfacial properties. The study addresses limitations of pure Li2OHCl, such as low ionic conductivity and phase transitions, by employing halogen substitution strategies. The findings suggest that fluorine substitution improves chemical stability and ionic transport properties, making it a promising approach for developing high-performance ASSBs.
