Abstract

The all-solid-state battery is a promising alternative to conventional lithium-ion batteries that have reached the limit of their technological capabilities. The next-generation lithium-ion batteries are expected to be eco-friendly, long-lasting, and safe while demonstrating high energy density and providing ultrafast charging. These much-needed properties require significant efforts to uncover and utilize the chemical, morphological, and electrochemical properties of solid-state electrolytes and cathode nanocomposites. Here we report solid-state electrochemical cells based on lithium oxyhalide electrolyte that is produced by melt-casting. This method results in enhanced cathode/electrolyte interfaces that allow exceptionally high charging rates (>4000C) while maintaining the electrochemical stability of solid-state electrolyte in the presence of lithium metal anode and lithium iron phosphate-based cathode. The cells exhibit long cycle life (>1800 cycles at 100 °C) and offer a promising route to the next-generation all-solid-state battery technology.
