Nuclear Diamond Batteries (NDBI) published a white paper outlining a proposed nuclear micropower architecture for long-life sensors using LoRaWAN wireless connectivity. The concept combines power generated from radioactive decay with energy storage to support intermittent sensing and transmission. NDBI has not built, tested, certified or commercialized a nuclear-powered LoRaWAN product; its energy budgets and reporting intervals remain conceptual or illustrative.
The proposed roadmap starts with laboratory energy-budget validation and a bench-scale demonstrator, then advances toward field pilots and application-specific products. Prototype development and field testing depend on successful laboratory validation. Through majority-owned subsidiary AtomiQ, NDBI holds U.S. Patent No. 12,394,534 B2 for a nuclear-voltaic power source and has received Notices of Allowance for two materials-related patent applications.
Nuclear Diamond Batteries (OTC: NDBI) outlined its U.S. intellectual property position and near-term patent strategy for its nuclear diamond battery platform, held via majority-owned subsidiary AtomiQ. As of July 2026, the company has three USPTO Notices of Allowance, including one issued as U.S. Patent No. 12,394,534 B2.
These cover core nuclear voltaic power-source architecture, high-porosity MOF electrodes with carbon nano-onion coatings, and proprietary synthesis/functionalization methods for carbon nano-onions. Additional applications on semiconductor structures, isotope integration, and energy-optimization systems are pending. Management plans to finalize issuances, advance examinations, pursue further U.S./international filings, and align IP with technical development and regulatory needs, while remaining in a pre-commercial development stage.
Nuclear Diamond Batteries (OTC:NDBI) received a third U.S. patent allowance, covering proprietary carbon nano-onion synthesis and functionalization (App. No. 18/015,242, 18 claims). This materials patent complements earlier allowances on nuclear voltaic power-source architecture and MOF electrodes, supporting a vertically integrated nuclear diamond battery IP platform managed via subsidiary AtomiQ, with space power systems as a core target market.
Nuclear Diamond Batteries (OTCID:NDBI) completed independent audits by a PCAOB-registered accounting firm for fiscal years ended May 31, 2024 and 2025. The company highlights this as strengthening financial reporting, transparency, and governance while supporting its long-term objective of a potential future uplisting to a major national exchange.
NDBI, through majority-owned subsidiary AtomiQ, develops proprietary betavoltaic nuclear diamond battery technologies designed to convert radioisotope emissions into long-duration electrical power for potential use in aerospace, medical, industrial, advanced computing, and other high-reliability applications.
Nuclear Diamond Batteries (OTC:NDBI) received a second U.S. patent allowance from the USPTO for 19 claims under application 17/928,967 covering a high-porosity MOF electrode with carbon nano-onion coatings for nuclear diamond batteries.
The patent complements an earlier allowed application (17/926,508) on nuclear voltaic core technology, supporting an integrated, potentially scalable ultra-long-life betavoltaic battery platform targeting mission-critical, low-power markets such as aerospace, defense, medical devices, IoT, and remote monitoring.
