New Polymer Enables Room-Temperature Lithium Batteries
1 min read
Researchers introduce a dual-salt self-healing polymer electrolyte achieving 2.23 mS cm⁻¹ ionic conductivity and a Li⁺ transference number of 0.55. The material allows stable operation for over 2,000 hours in symmetric cells. Full-cell tests show 75% capacity retention after 700 cycles for LiFePO₄||Li configurations and 72% retention after 250 cycles for NMC811||Li cells.
