Nuclear Diamond Batteries (OTC: NDBI) has received a second US patent from the USPTO for its subsidiary AtomiQ. Patent No. 12,759,882 covers methods for making carbon nano-onions from nanodiamond annealing and functionalizing carbon materials. The company says the technology could be used in electrodes, supercapacitors, and hybrid power systems for remote sensors and IoT devices. NDBI's first patent, issued earlier, covers a diamond-based nuclear-voltaic power source that converts radioisotope decay into electricity. Together they form the core of the company's push into long-life power sources for hard-to-service locations. The company has not yet commercialized a nuclear diamond battery, and it has not proven the technology will work in a finished product. NDBI is positioning itself for licensing deals and partnerships in aerospace, defense, industrial IoT, and other sectors where battery replacement is expensive. The new patent adds to a portfolio that also includes a metal-organic framework electrode application with carbon nano-onions.

Interesting to see NDBI stacking patents for carbon nano-onions and nuclear voltaic power. The materials side could matter for supercapacitors, but the release itself admits there is no commercial product yet. Worth watching whether they license the IP or just keep filing.

The patent is for synthesis methods, not a working battery. Carbon nano-onions have been around for a while, and making them from nanodiamond annealing is not new in every detail. The 18 claims will decide how much protection they actually have. No clear numbers on power output or lifetime either. What is a realistic power density for a cell that size?

On the materials side, carbon nano-onion electrodes could be useful for supercapacitors in grid or industrial settings, but the press release does not give specific capacitance or cycle life data. Without that, it is hard to compare with existing carbon materials. More of a patent milestone than a technical proof point.

The LoRaWAN angle is mostly context, not market share. 150 million devices does not mean they will use nuclear diamond cells. Regulatory questions around radioisotopes in consumer or industrial devices are a bigger hurdle than the patent. If they want real deployment, they need to show how this clears safety and disposal rules, not just claim a huge ecosystem.
