Invention Reference Number
This invention introduces a method for forming a solid-state electrolyte (SSE) directly in situ during battery assembly. The approach eliminates the need for separate electrolyte salts and achieves a robust interface between battery components in a single step. By integrating the SSE into the manufacturing process, this innovation reduces costs, simplifies fabrication, and enhances battery safety and performance.
Description
The process involves introducing a pre-lithiated anode into a solvent containing a polymerizable component. This component instantaneously polymerizes upon contact with the anode, forming a thin, uniform SSE layer that provides optimal interfacial contact. The SSE is highly organic, enabling better compatibility with electrode materials and improving manufacturing properties compared to conventional inorganic SSEs.
Benefits
- Cost-effective production: Simplifies the manufacturing process and reduces material costs by eliminating the use of electrolyte salts
- Enhanced interface quality: Ensures superior contact between the anode and SSE, improving battery performance and reliability
- Scalability: Enables efficient large-scale production with fewer steps and reduced energy requirements
- Improved safety: Removes liquid electrolytes, reducing risks of leakage, flammability, and combustion
Applications and Industries
- Electric vehicles: Enhancing battery performance and safety for EV applications
- Consumer electronics: Improving battery safety and longevity in portable devices
- Fuel cells: Providing advanced materials for alternative energy systems
- Renewable energy: Supporting efficient storage for wind, solar, and grid energy systems
