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 sil icon 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 is sue 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, enhancin g battery longevity and
efficiency.

Performance Testing and Next Steps
The technology has been successfully tested in coin cells, demonstrating increased battery
performance. Galvanostatic charge/discharge curves for coin cells made with 4.5% silicon
addition show that coating the SPG with carbon improves cycling stability and increases the
reversible capacity from 392 to 462 mAh/g which is 24% higher than the theoretical capacity of
graphite alone at 372 mAh/g.
Tests conducted on the 9% Si Enriched SPG showed that adding the silicon to the anode mix
before spheroidization increases the capacity from 530 to605 mAh/g, which is an additional 13%
boost in capacity, or an overall 62 % increase when compared with the t heoretical capacity of
graphite alone.
The next phase is to validate this technology through testing in a full -scale large commercial
battery. If the results remain consistent and positive in this phase, Focus intends to license the
technology to a 3rd party OEM or major battery manufacturers.
