VANCOUVER, BC / ACCESS Newswire / May 6, 2025 / Battery X Metals Inc. (CSE:BATX)(OTCQB:BATXF)(FSE:5YW,WKN:A40X9W)("Battery X Metals" or the "Company") an energy transition resource exploration and technology company, announces that its wholly-owned subsidiary, Battery X Recycling Technologies Inc. ("Battery X Recycling Technologies"), has achieved a key procedural milestone in its research collaboration with the Institute of Mining Engineering at a globally ranked Top 20 university (the "Global Top 20 University") for its proprietary eco-friendly froth flotation technology being developed.
As part of its ongoing work to optimize the recovery of battery-grade materials from end-of-life lithium-ion batteries, Battery X Recycling Technologies has identified a new solvent (the "New Solvent") that improves the separation of oxides from graphite using the Company's proprietary eco-friendly froth flotation technology. In recent controlled trials using 500g samples of unoxidized, Nickel-Manganese-Cobalt (NMC)-dominant black mass and Denver Cell flotation devices (the "Trials"), the application of the New Solvent led to a notable improvement in performance: oxide recovery in flotation concentrates (single-stage flotation) increased from 36.59% and 38.03% in prior tests (#3 and #4) to 48.10%, in the recent Trial, representing a relative increase of 26.5% to 31.5% (an absolute increase of 10.07 to 11.51 percentage points). Graphite purity also improved, increasing from 68.66% and 69.20% to 73.0%, representing a relative increase of 5.5% and 6.3% (an absolute increase of 3.80 to 4.34 percentage points) (the "Results"). The Results refer to the measured improvements in oxide recovery and graphite purity achieved through the application of the New Solvent during the Trials. These enhancements represent a notable improvement over the Company's prior results disclosed in its news release dated April 4, 2025. A comparison of the prior and current results is set out in the table below for reference.
Graphite Recovery & Grade Comparison
Parameter | Recent Trial Unoxidized Sample - pre-washed w/ New Solvent (Frother & Collector) | Prior Trial #3 (Unoxidized Sample - Frother-Only) | Prior Trial #4 (Unoxidized Sample - Frother & Collector) | Prior Trial #1 (Oxidized Sample - Frother & Collector, pre-washed w/ Prior Solvent) | Prior Trial #2 (Oxidized Sample -Frother & Collector, pre-washed w/ Prior Solvent & Water), |
Graphite Recovery (%) | 96.30% | 96.86% | 97.02% | 42.35% | 39.95% |
Graphite Grade (%) | 73.0% | 69.20% | 68.66% | 55.20% | 59.50% |
Metal Oxide Recovery & Grade Comparison
Parameter | Recent Trial Unoxidized Sample - pre-washed w/ New Solvent (Frother & Collector) | Recent Trial #1 (Frother-Only) | Recent Trial #2 (Frother & Collector) | Prior Trial #1 (Frother & Collector, pre-washed w/ Solvent) | Prior Trial #2 (Frother & Collector, pre-washed w/ Solvent), pre-washed w/ Solvent & Water) |
Metal Oxide Recovery (%) | 48.10% | 38.03% | 36.59% | 75.44% | 78.60% |
Metal Oxide Grade (%) | 89.90% | 89.37% | 89.57% | 64.68% | 62.45% |
Although oxide recovery appeared higher in prior tests #1 and #2 using the "Prior Solvent," those tests were conducted on oxidized black mass samples. In contrast, the recent Results were achieved using unoxidized black mass. Importantly, oxide purity using the New Solvent increased from 62.45% to 64.68% in prior tests #1 and #2 to 89.90% in the recent trials, representing a relative increase of approximately 39.0% to 44.0% (an absolute increase of 25.22 to 27.45 percentage points). This improvement highlights the New Solvent as a materially more effective solution for oxide recovery.
In addition to the improved recovery and purity metrics, other key parameters remained stable. Graphite recovery held steady at approximately 97% (96.30%), and oxide purity remained consistent at approximately 90%. Flotation times were unchanged from earlier trials, with effective separation occurring within approximately 5 to 7 minutes. As with prior tests, graphite purity was determined through burn-off assays conducted at 750°C for two hours, which quantify residual oxide content to validate separation efficiency.
Significance of Procedural Milestone
The identification of the New Solvent represents a significant procedural milestone for Battery X Recycling Technologies. Efficient separation of oxides from graphite is critical to unlocking high-purity outputs, and the New Solvent enables this separation more effectively than previously achieved. The improvements are expected to contribute meaningfully to the Company's goal of maximizing recovery yields of battery-grade materials.
This development also addresses a long-standing technical challenge identified during joint research: a rubber-like coating found on black mass samples, believed to be a by-product of thermal and chemical degradation during battery use. This coating was previously observed to inhibit optimal separation of oxides from graphite. Battery X Recycling Technologies and the Global Top 20 University successfully analyzed and identified the composition of the coating on this specific sample of black mass, enabling a targeted treatment strategy using the New Solvent. To date, it has demonstrated the most promising results in overcoming this barrier.
The Trials conducted to date have utilized a single-stage flotation process. Building on this preliminary achievement, Battery X Recycling Technologies and the Global Top 20 University are actively pursuing additional controlled trials using different solvent dilutions and/or multi-stage flotation processes, with the goal of further improving the Results. The objective is to further improve battery material recovery and purity metrics through its proprietary froth flotation process optimization and refinement. The Company anticipates sharing further results as they become available.
"These encouraging results mark an important step forward in our mission to develop eco-friendly solutions for battery material recovery," said Massimo Bellini Bressi, CEO of Battery X Metals. "The identification of this new solvent not only improves the performance of our flotation process, but also validates our collaborative approach to innovation. We're excited by the potential of these findings and look forward to further optimizing the technology as we advance toward further validation."
Lithium-Ion Battery Recycling Industry Tailwinds and the Significance of Graphite Recovery
Battery X Metals, through its wholly-owned subsidiary Battery X Recycling Technologies, is advancing sustainable lithium-ion battery recycling through its amended research collaboration agreement with the Global Top 20 University. The research focuses on proprietary froth flotation technology under development to recover critical battery-grade materials-graphite, lithium, nickel, cobalt, manganese, and copper-from end-of-life lithium-ion batteries, supporting a circular battery economy.
Graphite, comprising 95% of lithium-ion battery anodes1, is often neglected in traditional hydrometallurgy and pyrometallurgy recycling methods2. Battery X Metals' process shows promise to enable the separation of cathode-active metal oxides from anode-active graphite without degradation, unlike high-temperature treatments3 and chemical leaching4 processes such as pyrometallurgy and hydrometallurgy.
In October 2024, Mercedes-Benz (FSE:MBG) opened Europe's first battery recycling plant, integrating mechanical-hydrometallurgical processes and becoming the first automotive manufacturer worldwide to establish an in-house battery recycling loop 5, underscoring the industry's shift toward battery recycling.
Further emphasizing the industry's momentum, Redwood Materials, Inc., founded by Tesla co-founder and former Chief Technology Officer J.B. Straubel, became the exclusive battery recycling partner for Lime's shared scooters and e-bikes in April 2025. This collaboration, covering operations in the United States, Germany, and the Netherlands, aims to recycle end-of-life batteries, thereby enhancing the domestic supply of critical materials and improving battery recycling supply chains6.
Redwood Materials has also established partnerships with major companies such as Ford, Panasonic, BMW, General Motors, and Toyota. The company has received a $2 billion conditional loan from the U.S. Department of Energy to build and expand a battery materials campus in Nevada, supporting the growing electric vehicle market in America7,8.
The global shift toward electrification is driving the clean energy transition, with lithium-ion batteries playing a central role in reducing reliance on fossil fuels9. Global lithium-ion battery demand is projected to rise 670% by 203010 with energy storage requirements rising from 700 GWh in 2022 to 4.7 TWh10, primarily due to the increased adoption of EVs10. Yet, recycling remains underutilized, with less than 5% of batteries currently recycled11. EVs and battery storage will account for nearly half of mineral demand growth from clean energy technologies over the next two decades12, making the recovery of materials like graphite, lithium, nickel, and cobalt critical.
As the industry prioritizes battery recycling, Battery X Metals' eco-friendly technology stands out by recovering battery-grade graphite-anode material often lost in conventional methods. This positions Battery X Metals to address a major gap in the growing battery recycling market.
