Sulfide-based Electrolytes
Solid Electrolytes for Lithium-ion Batteries
Sulfide-based solid electrolytes are one of the most highly sought and have emerged as a leading contender in the quest for safer and higher-performance solid-state batteries. NEI Corporation, a trusted manufacturer of sulfide-based solid electrolytes, is at the forefront of the transition to solid-state batteries. Our advanced materials provide the foundation for a new era of energy storage technology. Some key advantages of sulfide-based solid electrolytes include:
- High Ionic Conductivity – contributing to faster charge-discharge rates
- Wide Electrochemical Window – enabling compatibility with high-voltage cathode materials
- Potential for High Energy Density – contributing to increased battery capacity
Although it is important to note that these materials are air and moisture sensitve, the potential benefits of sulfide-based solid electrolytes make them a promising avenue for next-generation battery technologies.
Available Sulfide Compositions
Sulfide compounds with high Li-ion conductivity are not commonly available, and so the development of solid state electrolyte-based Li-ion batteries has been plagued by the lack of widespread availability of these difficult-to-produce materials. NEI has leveraged its expertise in advanced materials synthesis to develop a proprietary process for producing sulfide materials in a form suitable for lithium-ion battery applications. This capability positions NEI as a potential partner for researchers and manufacturers seeking to advance solid-state battery technology.
