Focus Graphite Advanced Materials Provides Update on Patent Pending Silicon-Enhanced Spheroidized Graphite Technology for Battery Anodes
Focus Graphite Advanced Materials (TSXV:FMS, OTCQB:FCSMF) has provided an update on its patent-pending silicon-enhanced spheroidized graphite technology for lithium-ion battery anodes. The company has pending patent applications in the United States, Canada, Europe, and South Korea.
The innovative technology incorporates multiple layers of silicon during sphere creation, unlike conventional methods that apply a single silicon coating after spheroidization. This approach addresses key challenges in silicon-enhanced anode materials, including charge-induced volume expansion and unreliable solid electrolyte interphase propagation.
Performance testing in coin cells has shown significant improvements: 4.5% silicon addition increased reversible capacity from 392 to 462 mAh/g, while 9% Si Enriched SPG boosted capacity from 530 to 605 mAh/g - a 62% increase compared to graphite alone. The company plans to validate the technology through full-scale commercial battery testing before pursuing licensing opportunities with OEMs or major battery manufacturers.

Innovation Highlight
Focus Graphite Advanced Material's patent-pending silicon-enhanced spheroidized graphite technology represents a breakthrough in lithium-ion battery performance. Unlike conventional approaches where silicon is coated onto the graphite sphere after spheroidization-resulting in a single silicon layer-Focus Graphite Advanced Material's proprietary process incorporates multiple layers of silicon as the sphere is being created. This allows for significantly increased silicon content, which is crucial because silicon has 7 to 8 times the energy storage capacity of graphite.
This novel approach directly addresses two major challenges in silicon-enhanced anode materials:
- Charge-induced volume expansion: Conventional single-layer silicon coatings tend to swell during charging, leading to structural instability. By embedding silicon within the graphite layers, Focus Graphite Advanced Material's technology mitigates this issue and provides superior mechanical integrity.
- Unreliable solid electrolyte interphase (SEI) propagation: Silicon interacts with the electrolyte, causing performance degradation over time. The protective graphite layers in Focus Graphite Advanced Material's technology reduce these reactions, enhancing battery longevity and efficiency.
Performance Testing and Next Steps
