Focus Graphite’s Lac Knife Material Passes C4V Validation Testing, Advances to Next-Stage Battery Qualification

Independent U.S. laboratories confirm Phase I battery performance, paving the way for pouch cell and OEM-scale testing

Ottawa, Ontario–(ACN Newswire via SeaPRwire.com – October 22, 2025) – Focus Graphite Inc. (TSXV: FMS) (OTCQB: FCSMF) (FSE: FKC0) (“Focus” or the “Company“), a leading developer of high-grade flake graphite deposits and innovator of next-generation lithium-ion battery technology, is pleased to announce that its Lac Knife graphite anode material has successfully passed Phase I battery validation testing, conducted by both Charge CCCV LLC (“C4V”) and American Energy Technologies Company (“AETC”). The concurrent, independent U.S. laboratory test programs confirmed that Lac Knife natural graphite achieved near-theoretical electrochemical capacity (~371 mAh/g), demonstrating high purity, crystallinity, and strong suitability for lithium-ion battery anode applications. The successful completion of these evaluations represents a major milestone toward commercial-scale qualification within C4V’s global supply-chain program and future OEM-level validation.

The testing was conducted using material refined at AETC under Focus’s direction. AETC performed control testing based on its established parameters for Focus’s graphite, while C4V carried out independent validation through its proprietary Digital DNA™ (“DDNA“) program, which applies industry-standard cell performance benchmarks. Despite minor variations inherent to coin-cell assembly and laboratory calibration, both laboratories confirmed that Focus’s Lac Knife material exceeded internal baseline qualification thresholds. Based on these results, C4V has advanced the material to Phase II of its qualification program, which includes pouch-cell fabrication and large-format validation for commercial-scale evaluation. In parallel, Focus plans to explore additional large-format testing initiatives with AETC to further assess scalability and performance consistency.

Under identical test conditions, Focus’s natural graphite (lot number GN250619002) was compared to C4V’s baseline synthetic graphite reference material. The Focus sample achieved a first-cycle discharge capacity of approximately 373 mAh/g-essentially reaching the theoretical maximum for graphite-while exhibiting good stability. Although electrode density and long-cycle performance were modestly lower than the baseline, the material surpassed C4V’s qualification benchmarks, confirming its readiness for large-format pouch-cell validation-a more accurate and scalable measure of performance using a semi-automated testing platform that directly correlates with electric-vehicle (“EV“) and energy-storage-system (“ESS“) cell designs required by original equipment manufacturers (“OEMs“).

The Company previously demonstrated strong lithium-ion battery performance from its Lac Knife material; however, these independently verified, third-party results now supersede earlier findings and establish a modern, industry-standard baseline that will support future offtake qualification and commercial evaluation.

“These results validate the quality of our Lac Knife graphite and its suitability for next-generation anode production,” said Dean Hanisch, CEO of Focus Graphite. “Having both AETC and C4V confirm the material’s strong performance gives us confidence as we move into pouch cell testing – the next step toward commercial readiness.”

“C4V is pleased to see Focus Graphite’s Lac Knife material successfully complete our Phase 1 validation process under our DDNA program,” said Baasit Ali, VP Supply Chain at C4V. “The material has demonstrated strong electrochemical validation and purity characteristics that align well with our high-performance anode requirements. We look forward to advancing into pouch cell fabrication and validation, which will provide a clearer picture of its scalability for EV and ESS applications.”

Next Steps

• Fabrication and testing of pouch cells using Focus’s Lac Knife graphite by C4V
• Long-term cycling and safety validation under C4V’s DDNA qualification program
• Subsequent scaling to large-format cell testing with industry partners for commercial qualification

Focus Graphite’s continued collaboration with C4V and AETC underscores its commitment to establishing a North American supply of high-performance, ESG-compliant graphite anode material, supporting the energy transition and critical minerals independence objectives shared by both Canada and its allies. The Company will continue to prioritize dual-use battery initiatives serving both civilian and defense-sector applications.
