Overview

Randomized trial showcases enhanced cycling stability in lithium metal batteries, suggesting improvements for energy density.

Key Points

  • This research aims to enhance the cycling stability of lithium metal anodes by regulating lithium plating and stripping processes effectively.
  • Developed a lithium metal anode with a LiF-rich solid electrolyte interphase using alloy modifications and a carbon host.
  • Applied density functional theory (DFT) calculations to understand the electronic structure of alloys.
  • Tested cycling performance in symmetric cells and full cells with various cathode materials.
  • Symmetric cells maintained high cyclability for over 1200 hours with a low overpotential of 23 mV at 2 mA cm−2.
  • Full cells with LiFePO4 and LiNi0.8Co0.1Mn0.1O2 cathodes achieved 131.5 mAh g−1 after 400 cycles at 1 C rate.
  • Pouch cells showed 90.3% capacity retention after 90 cycles, indicating strong cycling stability.
