Balanced Anion-Cation-EO Interaction Enables Ultrahigh Lithium-Ion Transport in 4.5 V-Class PEO-Based All-Solid-State Lithium Batteries
{{output}}
The sluggish lithium-ion transport in high-concentration polyethylene oxide (hc-PEO) solid electrolytes (SEs) and across the electrode/hc-PEO SE interface causes failure of high-voltage PEO-based all-solid-state lithium batteries (ASSLBs). Here, bi-salt hc-PEO... ...
