A research team from Tsinghua University and Tianjin University has developed a silver-based, flexible "armor" that stabilizes the most fragile part of solid-state cells.
The coating delivers 4,500+ hours and 7,000 hours at –30 °C, resisting cracking and performing in deep cold.
The race to build better EV batteries has a new front-runner: a solid-state EV battery coating that resists cracking and performs in deep cold.
Solid-state batteries replace flammable liquid electrolyte with a solid one, promising higher energy density and better safety.
The core barrier to commercialization is real-world durability, which this coating targets.
