Randomized trial shows improved ionic conductivity in lithium-metal batteries, suggesting enhanced safety and performance.

Key Points

This research aims to develop a composite solid electrolyte that suppresses dendritic growth and enhances ionic conductivity in lithium-metal batteries.
Developed a tri-layered composite solid electrolyte using PEO/LiTFSI and PDA@LLZO.
Conducted testing of ionic conductivity at various temperatures and constructed Li/LFP full cells for performance evaluation.
Evaluated mechanical compliance and stress redistribution using PPP elastomers.
Optimized CSE-30 achieved an ionic conductivity of 5.60×10 −3 S cm − 1 at 60°C, four times higher than PEO.
In Li/LFP full cells, CSE-30 delivered a capacity of 133.6 mAh g − 1 at 0.5C with 80% retention after 1000 cycles.
Li/Li symmetric cells with the optimized CSE sustained over 1000 hours of cycling without short-circuiting.
