Abstract
(70 to 100 cycles) and thin-Li‖high-loading-LFP coin cells (200-300 cycles). Overall, we demonstrated and rationalized the improvement in Li metal cyclability by the acetal structure compared to ethylene glycol ethers. We expect further improvement in performance by tuning the acetal structure.
