Sn-Carbon Nanocomposite Anode for All-Solid-State Chloride-ion Batteries Operating at Room Temperature

Abstract

All-solid-state chloride-ion batteries promise high theoretical energy density and room-temperature operation. However, conventional Sn anodes suffer from low material utilization attributed to large particle size and volume expansion. Here, nano-sized Sn particles in an N-doped carbon framework are used as an anode, resulting in ~12% higher capacity compared to conventional Sn, due to improved Sn utilization and suppression of volume expansion.
