Silicon-Rich Anodes for Higher-Energy Batteries
A high-capacity graphene/silicon composite platform designed to increase energy density while addressing key challenges associated with silicon anodes.

Silicon can store substantially more lithium than conventional graphite, making it one of the most promising materials for increasing battery energy density. Its challenge is equally significant: silicon expands and contracts dramatically during cycling, which can damage the electrode and reduce battery life.
Solidion’s GCA-Si platform is designed to address this challenge by combining silicon with graphene-based protection and engineered composite structures.
Designed for Performance and Manufacturability
Solidion has developed patented approaches intended to deliver high silicon content without relying on silane-based chemical vapor deposition. This provides a potential pathway toward simpler, scalable production while preserving the performance advantages of silicon.
Key Technology Attributes
- High-capacity silicon-rich composite anode platform
- Graphene-enabled structures designed to help manage silicon expansion
