Abstract
Abstract Electrochemical batteries with organic electrode materials have attracted worldwide attention due to their high safety, low cost, renewability, low contamination, and easiness of recycling. However, the practical application of such system is limited by low density, low electronic/ionic conductivity, and the dissolution of organic electrode materials in conventional liquid electrolytes. Herein , a novel battery configuration is proposed to replace liquid electrolyte/solid organic cathode with solid electrolyte/liquid organic cathode to ultimately solve the shuttle effect and dissolution problem of organic cathodes. More importantly, this configuration combines room‐temperature high‐safety liquid lithium metal anode Li‐BP‐DME that can essentially inhibit lithium dendrite nucleation/growth and sulfide SE with ultrahigh room‐temperature ionic conductivity for facilitated ion‐conduction.
