Overview

Demonstrates enhanced energy conversion in Li/CFx batteries, suggesting a method to reduce heat and improve safety.

Key Points

  • The research aims to improve the efficiency of Li/CFx batteries by reducing parasitic heat release.
  • Identified primary energy loss pathway due to parasitic decomposition of metastable intermediate phase.
  • Introduced a solvation-mediated Gibbs free energy stabilization strategy to enhance Li+–solvent interaction.
  • Analyzed performance in practical multi-ampere-hour pouch cells.
  • Reduced heat generation by 39.6%.
  • Elevated discharge voltage from 2.50 to 2.92 V.
  • Achieved cell-level energy densities of 816–830 Wh kg−1.
