[{"type":"text","content":"Volt Carbon Reports Second U.S. Patent and New High-Performance Lithium-Metal Battery ResultsCalgary, Alberta--(Newsfile Corp. - December 3, 2025) - Volt Carbon Technologies Inc. (TSXV: VCT) (OTCQB: TORVF) (\"Volt Carbon\" or the \"Company\") is pleased to confirm the issuance of a second United States patent supporting the Company's dry-separation graphite platform and reporting of new technical results from its lithium-metal battery development program. Recent work at the Company's Guelph facility includes long-duration cycling, high-rate discharge testing, and expanded low-temperature evaluations.1. Second Patent Issued by the USPTO: \"Method and System for Aerodynamic Air Classification.\"Volt Carbon has received formal notification from the United States Patent and Trademark Office confirming that its patent allowance previously announced on October 2, 2025, will be issued as USPTO Patent Number 12491538 on December 9, 2025. This represents the Company's second issued patent for its air classification technology, further strengthening its intellectual property portfolio and supporting the aerodynamic separation method at the core of Volt Carbon's dry separation graphite purification technology. The Company has also released a new demonstration video showing the air classifier operating in real time. The video link is available on the Company's website. https://voltcarbontech.com/wp-content/uploads/2025/12/Air-Classifier.mp4.2. Lithium Metal Results: High Cycle Life and High Discharge CapabilityVolt Carbon has undertaken a series of evaluations across multiple li-metal loadings to determine the most effective configurations for both extended cycle life and high discharge performance. These studies form part of the Company's ongoing effort to refine its next generation lithium metal architecture.Volt Carbon is pleased to report that its lithium metal battery has now achieved 1600 cycles at a 0.75C discharge rate, as illustrated in Figure 1. This long duration cycling result demonstrates stable behaviour over a significant number of cycles. The cathode loading used for this single layer pouch cell is projected to support a 340 Wh/kg lithium metal configuration with parallel testing underway to advance the company's 400 Wh/kg design. Cycle life determines real-world battery longevity. Maintaining stability for 1600 cy...
