pH7 Technologies operates a commercial PGM extraction facility in Vancouver and is scaling its mining-sector applications beginning with copper. Its proprietary closed-loop organo-electrochemical process is designed to recover metals from low-grade sulfide ore, tailings, and complex feedstocks that have been historically uneconomic or challenging to process. The company’s proposed copper production approach aims to convert low-grade sulfide ore directly into 99.9% pure copper cathodes on-site while generating green hydrogen as a by-product. pH7 says the process could increase recovery from low-grade resources, extend the value of existing mining assets, and strengthen domestic critical mineral supply chains. Current plans include engineering and technology development phases to produce technical and economic data to support future demonstration and commercial deployment across the Canadian mining sector.

Mangrove Lithium is commercializing a feedstock-flexible electrochemical refining process that converts various lithium inputs into battery-grade lithium hydroxide or lithium carbonate, aiming to cut costs, carbon intensity, and waste relative to conventional methods. Proceeds from its latest raise will fund commissioning of a 1,000-tonne-per-year "Single Stack Plant" in Delta, British Columbia, expected to supply material for about 25,000 electric vehicles annually. The company is also conducting early engineering and site selection for a full-scale facility with up to 20,000-tonne annual capacity—enough for more than 500,000 EVs. By expanding onshore refining, Mangrove seeks to bolster Western battery-materials supply chains and lessen dependence on overseas processing. Existing strategic and financial backers include Breakthrough Energy Ventures, BMW i Ventures, Mitsubishi Corporation, Asahi Kasei, Orion Industrial Ventures, Export Development Canada, and BDC Capital. The firm’s technology and expansion plans position it at the intersection of cleantech manufacturing incentives and growing lithium demand for EV batteries.

24M delivers battery innovations by reinventing battery technologies and manufacturing methods through its SemiSolid™ and Unit Cell manufacturing platform. Its chemistry-agnostic design, process, and platform aim to reduce manufacturing costs while improving safety, range, performance, and recyclability. The company says its technology set addresses long-standing industry challenges in preferred energy storage products. 24M plans to accelerate commercialization and mass production of its offerings, including acquiring and opening a new R&D and pilot manufacturing plant in Rayong, Thailand. The company is headquartered in Cambridge, Mass. The recent financing brings total funding to over $500 million, supporting its push toward scaled production and market rollout. 24M develops a chemistry-agnostic SemiSolid™ manufacturing platform intended to lower the cost and improve performance of energy storage. The company has commercially demonstrated its ultra-thick SemiSolid electrode architecture with high energy density using lithium‑ion chemistry. 24M plans to adapt that platform to sodium metal batteries aimed at low‑cost, fast‑charging and wide‑temperature EV applications. It will partner with MIT and Carnegie Mellon University to apply a cell design that includes an ultra‑thick cobalt‑ and nickel‑free sodium cathode, an advanced wide‑temperature fast‑charging electrolyte developed with machine learning and high‑throughput screening, and a sodium super ionic conductor. The company is headquartered in Cambridge, Mass. Company leadership includes president and CEO Naoki Ota and Dr. JunZheng Chen, director of advanced R&D. 24M Technologies builds SemiSolid lithium‑ion cells and a redesigned manufacturing approach intended to reduce battery cost while improving performance. The company is advancing next‑generation high energy density lithium metal anode cells using its SemiSolid platform. 24M plans to combine a lithium metal anode with a SemiSolid cathode to deliver lower cost, superior power and improved energy density for electric aviation applications. The team is developing and scaling a commercial, modular pilot line for customer validation with a clear path to gigascale production capacity. A recent $9 million ARPA‑E award is intended to accelerate commercialization and rapid market entry. 24M is headquartered in Cambridge, Mass., and is founded and led by industry inventors and scientists including co‑founder Dr. Yet‑Ming Chiang and President & CEO Naoki Ota. 24M commercializes its SemiSolid™ lithium‑ion manufacturing platform that mixes electrolyte with active materials to form a binder‑free, clay‑like slurry. The process eliminates significant inactive materials and capital‑intensive steps such as drying and electrolyte filling, aiming to dramatically reduce manufacturing cost. 24M says the platform delivers market‑leading price‑performance and that it has improved cell performance and safety. The company is working with licensee partners, including Kyocera and GPSC, which have expanded commercial operations. Proceeds from the financing will be used to commercialize the SemiSolid manufacturing process and expand technology development programs for grid storage and electric vehicle applications. 24M is headquartered in Cambridge, Mass., and is led by industry inventors, scientists and entrepreneurs. 24M commercializes a SemiSolid lithium-ion battery design and a novel, capital-efficient manufacturing process that uses electrolyte as the processing solvent. The process eliminates steps such as drying, solvent recovery, calendaring and electrolyte filling, and reduces the need for inactive materials like copper, aluminum and separator. 24M says this approach yields a structural bill-of-materials advantage and lower manufacturing cost while enabling high energy density cell designs not previously possible. The company has used a semi-automated pilot facility to advance cell design and production readiness. 24M is targeting both the low-cost grid market and the high energy density requirements of the EV market and says it is ready to scale globally. The company is headquartered in Cambridge, Mass.
