STUTTGART — Physicists and electrochemists published peer-reviewed results today demonstrating a solid-state lithium-metal battery architecture capable of enduring four thousand ten-minute fast-charge cycles without internal short-circuiting.
By infiltrating a brittle garnet-type ceramic electrolyte with a nanometer-thin self-healing polymer lattice, the team eliminated microscopic lithium dendrite filaments that previously fractured solid separators under high current density.
Independent national laboratory replication confirmed that the cells operate at normal automotive pack pressures, removing a major mechanical obstacle to mass roll-to-roll manufacturing.
