Invention Reference Number
This technology provides a novel method for protecting interfaces within solid-state batteries to enhance long-term stability and performance. By addressing degradation at critical junctions between battery materials, it offers a promising route to more durable, high-capacity energy storage systems.
Description
The invention centers on protective formulations designed to stabilize interfaces among the solid electrolyte, carbon, current collector, and cathode materials in solid-state batteries. These protective formulations are applied to the catholyte, or the solid electrolyte, in the composite cathode of the battery. Similar formulations can be applied to anolytes and electrolytes to create stable anodes and electrolytes. The protective layer acts as a barrier to prevent chemical and electrochemical degradation at these contact points, supporting the integrity of ceramic-based solid-state batteries over extended charge-discharge cycles. Unlike conventional approaches that focus only on coating cathode active materials, this method ensures comprehensive protection across multiple Â鶹ӰÒô interfaces of the battery.
Benefits
- Enhances long-term capacity retention in solid-state batteries
- Reduces interface degradation across cathode, anode, and electrolyte layers
- Compatible with ceramic-based battery architecture
Applications and Industries
- Advanced battery systems for electric vehicles
- Grid-scale energy storage solutions
- Consumer electronics and portable power systems
