This technology introduces a solid-state battery architecture using a glass matrix composite that functions as both electrolyte and structural component. It addresses key limitations of conventional solid electrolytes, such as brittleness, poor interfacial transport, and susceptibility to internal shorting. By combining a deformable glass matrix with ion-conducting ceramic phases, the system enables improved ionic transport and mechanical resilience. The result is a robust, manufacturable battery design suitable for advanced energy storage applications where durability and performance are critical.
Description
The innovation centers on a composite material composed of a lithium-ion-conducting glass integrated with dispersed ceramic phases to form a unified electrolyte structure. Unlike traditional polymer-based composites, where ion transport is limited by mismatched mechanisms between phases, this approach enables more uniform ion movement across the material. The glass matrix exhibits low melting temperature and viscoelastic behavior, allowing it to be processed with active battery materials without inducing structural degradation. This enables formation of integrated composite layers that combine electrolyte and electrode functionality.
The absence of grain boundaries in the glass phase reduces pathways for internal shorting, while the composite structure improves mechanical compliance and resistance to fracture. The material system also supports stable interfaces and accommodates internal stresses during operation. Overall, the design represents a shift toward multifunctional battery components that integrate mechanical integrity with electrochemical performance.
