A Composite Solid Electrolyte for All solid state Lithium ion Batteries

The Solid-Electrolyte Interphase

For years, the energy density ceiling and flammability of liquid-state batteries were considered a fixed trade-off. Donut Lab is challenging that paradigm with a proprietary ceramic electrolyte that replaces the traditional “slush” with a solid crystal lattice. The Technical Breakdown: • Ion Transport: A solid-state highway allowing ions to “teleport” through the structure, bypassing the resistance of liquid solvents. • Energy Density: Achieving 400 Wh/kg—nearly double the gravimetric energy den
