Dual-Salt Electrolyte Additives Enabled Stable Lithium Metal Anode/Lithium-Manganese-Rich Cathode Batteries

Popis výsledku v původním jazyce

Although lithium (Li) metal anode/lithium-manganese-rich (LMR) cathode batteries have an ultrahigh energy density, the highly active Li metal and structural deterioration of LMR can make the usage of these batteries difficult. Herein, a multifunctional electrolyte containing LiBF4 and LiFSI dual-salt additives is designed, which enables the superior cyclability of Li/LMR cells with capacity retentions of approximate to 83.4%, 80.4%, and 76.6% after 400 cycles at 0.5, 1, and 2C, respectively. The dual-salt electrolyte can form a thin, uniform, and inorganic species-rich solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI). In addition, it alleviates the bulk Li corrosion and enhances the structural sustainability of LMR cathode. Moreover, the electrolyte design strategy provides insights to develop other high-voltage lithium metal batteries (HVLMBs) to enhance the cycle stability.
