Solid-State EV Battery Coating Breakthrough
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.
What is the Coating?
The coating is a solid-state EV battery coating that replaces flammable liquid electrolyte with a solid one, promising higher energy density and better safety.
How it Works
The coating targets the core barrier to commercialization: real-world durability, by stabilizing the solid electrolyte interphase (SEI), the most fragile part of solid-state cells.
The swap promises higher energy density and better safety.
Why it Matters
The breakthrough has the potential to make solid-state batteries more durable and efficient, making them a more viable option for electric vehicles.
