WebFeb 3, 2024 · Since the dissolution and shuttle of polysulfides all happen in the electrolyte, the design of a suitable electrolyte environment seems to be quite crucial. So far, electrolytes based on various ethers such as 1,3-dioxolane (DOL) and 1,2-dimethoxyethane (DME) are widely used in the Li–S batteries. WebAn emerging ether-based electrolyte of mixed-DIPE was proposed to forcefully protect the Li metal anode in working Li‒S batteries with SPAN cathodes. Compared with routine EC/DEC or DOL/DME electrolyte, the mixed-DIPE electrolyte contributed to stable cycling for over 120 cycles in Li Cu half-cells and superior long-term cycling stability ...
