Overview

The study demonstrates enhanced cycling performance in lithium-metal batteries using a protective layer, indicating improved stability.

Key Points

  • The aim is to enhance the cycling lifetime and safety of lithium-metal batteries by using a single-ion-conducting protective layer.
  • Developed a hybrid single-ion-conducting protective layer (SPL-20) for Li-metal batteries.
  • Conducted electrochemical measurements and simulations to analyze performance.
  • Tested battery configurations including anode-free and various cathode combinations.
  • Achieved a capacity retention of 59% after 50 cycles in the anode-free LiFePO4/SPL-20@Cu cell.
  • Demonstrated a specific capacity of approximately 110 mAh g-1 at 2C in the LiFePO4/SPL-20@Li cell.
  • The NCM811/SPL-20@Li cell maintained specific capacities of 172 mAh g-1 at 25 °C and 143.1 mAh g-1 at -25 °C after 100 cycles.
