Investigating and inhibiting cathode-side gas generation for practical low-temperature and fast Li-ion batteries (opens in new tab)

Weakly solvating electrolytes attract increased interest in low-temperature lithium-ion batteries since they can overcome the kinetic limitations of lithium-ion desolvation. However, the high content of weakly-coordinating/free solvents poses a threat to the oxidative stability of weakly solvating electrolytes. Herein, we investigate the oxidation and gas-producing behaviour of weakly solvating electrolytes with typical low-melting-point solvents inside low-temperature pouch cells. Excluding ...
