Volt Carbon Technologies Receives Notice of Allowance for Second U.S. Patent on Air Classifier Technology, Reports Graphene Achievement, and Announces Stock Option Grant

Executive Summary

• Volt Carbon received a USPTO Notice of Allowance for a continuation U.S. patent (Application No. 18/782,462) expanding protection for its air‑classifier technology.
• The company produced reduced graphene oxide (rGO) sheets from its proprietary graphite, achieving 40‑60 % improvement in epoxy mechanical properties—demonstrating strong potential for aerospace composite applications.
• An aggregate of 6,500,000 stock options were granted to officers, employees and contractors at $0.05 per share, vesting immediately.

Key Details

• Patent Allowance: USPTO issued a Notice of Allowance for continuation application No. 18/782,462 (continuation of U.S. Patent No. 12,172,192). Issue fee payment pending; once paid, the patent will be assigned a number and issue date, broadening scope of air‑classifier protection.
• Graphene Oxide Production:
• Produced reduced graphene oxide (rGO) from Berkwood flake graphite processed via Volt’s proprietary air classifier.
• Generated five‑layer rGO sheets up to ~16.5 µm wide; verification by University of Waterloo’s Chemical Engineering Department using TEM imaging.
• Incorporated rGO into aerospace‑grade epoxy matrix; mechanical testing showed 40‑60 % improvement in strength compared with virgin epoxy.
• Commercial Implications: Results suggest Volt Carbon’s rGO can mitigate brittleness and interlaminar cracking in carbon‑fiber reinforced polymers, enabling lighter, tougher aircraft structures and opening partnership opportunities in aerospace composites and advanced materials markets.
• Stock Option Grant:
• 6,500,000 options granted under the Company’s Stock Option Plan.
• Exercise price: $0.05 per share; term: five years; vesting: immediate upon grant.
• Grants approved by TSX Venture Exchange and issued to officers, employees, contractors, and directors.
• CEO Quote: “The allowance for the second patent further reinforces our air classifier technology platform…the granting of stock options is a way to recognize and reward the dedication of our team…” – V‑Bond Lee, CEO, President & Chairman.
