Multiple protective layers for suppressing Li dendrite growth and improving the cycle life of anode-free lithium metal batteries
Technology Introduction:
This technology features a dual-protective coating on a copper current collector that, during charge/discharge, self-assembles in-situ to form multiple lithiophilic alloy layers (Li-Sn/Li-Sr) and a stable, LiF-rich interphase. This effectively suppresses dendrite growth, enabling high-energy-density, long-life anode-free lithium batteries.
Industry Applicability:
This technology is applicable to next-generation, high-energy-density batteries, meeting the demands of electric vehicles, consumer electronics, and grid energy storage. The manufacturing process uses mature immersion and coating methods, offering high compatibility with existing lithium-ion battery production lines, cost-effectiveness, and strong potential for mass production and commercialization.
