Solid-state lithium-metal batteries (SSLMBs) are the holy-grail of next-generation energy storage, but their commercialization has been stymied by dendrite growth, fragile interfaces, and the ion-conductivity vs. mechanical-strength trade-off. Now, researchers from Sichuan University, led by Prof. Yu Wang and Prof. Xuewei Fu, have introduced a “lithium-ion dynamic interface (Li⁺-DI)” strategy that turns charged halloysite nanotubes (HNTs) into nano-interfacial engineers, delivering composite polymer electrolytes (NCCPEs) that are simultaneously super-tough, highly conductive, and dendrite-suppressing.
