First Phosphate Provides Commercial Results for LFP Battery Cells Produced Using North American Critical Minerals
First Phosphate (OTCQX: FRSPF) has announced successful commercial testing results for its PHOS - LFP 18650 Battery Cells, manufactured using North American-sourced critical minerals. The cells demonstrated consistent performance with 1.6Ah capacity and projected 80% capacity retention after 2000 discharge cycles.
The battery cells were produced using materials from North American suppliers: phosphate and iron from First Phosphate's Bégin-Lamarche property in Quebec, lithium from Century Lithium in Nevada, and graphite from Nouveau Monde Graphite in Quebec. The cells showed stable performance, minimal cell-to-cell variability, and good voltage stability even at high discharge rates.

- None.
- Small development run with no prior production history
- Limited testing data compared to established manufacturers
Saguenay, Quebec--(Newsfile Corp. - September 3, 2025) - First Phosphate Corp. (CSE: PHOS) (OTCQX: FRSPF) (FSE: KD0) ("First Phosphate" or the "Company") announced on July 7, 2025 that it had successfully produced commercial-grade lithium iron phosphate ("LFP") 18650 format battery cells ("PHOS - LFP 18650 Battery Cells") using North American-sourced critical minerals, advancing its mission to localize the LFP battery supply chain in North America.
Today, First Phosphate is pleased to announce the results of the commercial cell testing of its PHOS - LFP 18650 Battery Cells that have demonstrated the following performance:
Battery cell capacities measured during cell testing successfully met the original manufacturing specifications (See Cell Capacity Testing Results graph below).
Retention of battery cell capacities remained consistent at increasing discharge rates. This is significant given that the cells produced were from a small development run made with new critical materials and without prior history.
Battery cells tested exhibited consistent and stable performance with minimal cell-to-cell variability.
Battery cell cycle life experienced favorable retention of at least
80% initial capacity projected after 2000 discharge cycles.In conclusion, the PHOS - LFP 18650 Battery Cells tested are well suited for high-performance applications requiring both energy density and power capability. Battery cells showed good relative voltage stability on full discharge even up to 5C rate of current.
"The production of these commercial grade PHOS - LFP 18650 Battery Cells shows that North America does have the ability to support an end-to-end LFP battery supply chain using our own critical mineral inputs," says First Phosphate CEO, John Passalacqua.

The PHOS - LFP 18650 Battery Cells were tested for capacity by discharging them at a typical C/5 rate of current. The graph above for four of the tested cells shows a consistent capacity of just over 1.6Ah which is in line with other similar commercially produced LFP 18650 format battery cells on the market.
The LFP cathode and anode materials for the PHOS - LFP 18650 Battery Cells were produced using North American critical minerals from the following supply sources:
Phosphate: High-purity phosphoric acid produced from igneous phosphate concentrate extracted from the First Phosphate Bégin-Lamarche property in the Saguenay-Lac-Saint-Jean region of Quebec, Canada and processed in the pilot installations of Prayon Technologies of Belgium, Europe.
Iron: Iron powder produced using magnetite concentrate from the First Phosphate Bégin-Lamarche property in Quebec, Canada and processed by GKN Hoeganaes of Tennessee, USA.
Lithium: Lithium carbonate produced by Century Lithium Corp. (TSXV: LCE) from its operations in Nevada, USA.
Graphite: Natural graphite-based active anode material produced by Nouveau Monde Graphite (NYSE: NMG) (TSX: NMG) from its operations in Quebec, Canada.
