A Pore?Forming Strategy Toward Porous Carbon?Based Substrates for High Performance Flexible Lithium Metal Full Batteries

Self-standing carbon-based substrates with satisfied structural stability and property adjustability have promising applications in flexible lithium (Li) metal batteries (FLMBs). Current strategies for modifying carbon materials are normally carried out on powder carbon, very few of them suitable self-standing substrates. Herein, a pore-forming strategy based the redox chemistry metallic oxide nanodots is developed to prepare two porous anode cathode. Starting cotton cloth, resulting hollow fibers substrate nanopores effectively prevents from Li dendrites formation large volume change (LMA). Simulations indicate that structure leads homogeneous ion flux, Li-ion concentration, electric field during deposition. symmetrical cell this remains stable 8300 h an ultralow voltage hysteresis 9 mV. Via similar route, cloth obtained subsequently seeding V2O5 nanowires The assembled FLMBs pouch delivers capacity 8.2 mAh high retention ~100% even under dramatic deformation. demonstrated has far-reaching potential preparing free-standing energy storage devices.
