Star Metro - Nano One Successfully Commissions Proprietary Agitator Equipment Boosting Throughput Capacity at Candiac Five New Patents Added to Global IP Portfolio

VANCOUVER, BRITISH COLUMBIA / ACCESS Newswire / August 20, 2025 / Nano One® Materials Corp. (TSX:NANO)(OTCQB:NNOMF)(Frankfurt:LBMB) ("Nano One" or the "Company"), a process technology company specializing in lithium-ion battery cathode active materials (CAM), is pleased to report that it has successfully installed and commissioned a custom-designed and proprietary agitator in its commercial-sized 20,000 litre One-Pot reactor at its production facility in Candiac, Québec-further improving its cost performance, in addition to supporting production scale-up and continued product commercialization, as well as optimizing plant design for the Company's future licensing business.

The newly installed, high-efficiency agitator has been engineered to enhance mixing dynamics, thermal transfer and reaction time and is estimated to increase the throughput capacity of the reactor by approximately 50%. It will also improve the consistency and quality of CAM output, while yielding reduced operating expenses (OPEX). The upgrade followed extensive piloting, data collection and modelling conducted on smaller 2,000-litre One-Pot pilot reactors, which were commissioned in October 2023.

"The successful commissioning of the new equipment marks an important milestone in the further optimization of the Candiac operations, which has been established as a One-Pot LFP demonstration production plant," said Denis Geoffroy, Chief Commercialization Officer of Nano One. "The upgrade was achieved through the combined efforts of our engineering and production teams. With their decades of commercial experience, the teams have continued to focus on continuous improvement and cost competitiveness of the technology. This achievement underscores the scalability of the One-Pot process."

The upgraded agitator and reactor design is full-scale and representative of the systems planned for future One-Pot enabled commercial-scale plants. This upgrade will support ongoing product validation and business development initiatives with key customers and commercial partners, while reinforcing the value proposition of Nano One's One-Pot technology to prospective licensees. Many of these engagements have focused on a subset of customers across battery energy storage systems (BESS), which in the past eighteen months have seen robust global demand increases driven by accelerated growth in the AI data center, military, and grid optimization market segments.

The new equipment was sourced from a leading German manufacturer specializing in mixing technologies. Nano One continues to establish a robust equipment supply chain, which can be shielded from potential disruption and geopolitical risk-especially following China's July 2025 announcement imposing export restrictions on key equipment and technologies related to LFP cathode manufacturing.

This project is supported by funding and expense reimbursements from NRC IRAP Clean Technology Program (formerly SDTC), Investissement Québec, Technoclimat, and US Department of Defense (DoD).

Nano One Adds Five New Patents To Its IP Portfolio
Nano One is pleased to announce the allowance and/or issuance of five new patents in North America and Asia to its portfolio of intellectual property (IP), bringing its total now to fifty-two granted, one allowed and fifty-four pending in jurisdictions around the world. These patents strengthen Nano One's independence from foreign controlled IP and enhance the Company's technological edge in a continually evolving market.
