Canadian mining and battery technology developer Focus Graphite Advanced Materials has announced that its Lac Knife graphite anode material has passed Phase I battery validation testing, conducted by Charge CCCV (C4V) and American Energy Technologies.

The concurrent US laboratory test programs confirmed that natural graphite from the company’s Lac Knife mine achieved near-theoretical electrochemical capacity of ~371 mAh/g, demonstrating high purity, crystallinity, and strong suitability for lithium-ion battery anode applications.

The completion of the evaluations marks a step toward commercial-scale qualification within C4V’s global supply-chain program and future OEM-level validation.

The testing was conducted using material refined at American Energy Technologies under Focus’s direction. American Energy Technologies performed control testing based on its established parameters for Focus’s graphite, while C4V carried out independent validation through its Digital DNA (DDNA) program, which applies industry-standard cell performance benchmarks.

Based on the results, C4V advanced the material to Phase II of its qualification program, which includes pouch-cell fabrication and large-format validation for commercial-scale evaluation. Focus also plans to explore additional large-format testing initiatives with the company to further assess scalability and performance consistency.

“The material has demonstrated strong electrochemical validation and purity characteristics that align well with our high-performance anode requirements.” said Baasit Ali, VP Supply Chain at C4V. “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.”
