Self-charging, thousand-year battery startup NDB aces key tests

"NDB is a nano battery technology that generates electrons by converting the radiation energy from the energetic electron. Energetic electrons released from the nuclide of carbon, carbon-14.

...the energetic electron release mechanism where a carbon-14 atom decays into nitrogen, an anti-neutrino (which are both harmless and clean) and an energetic electron.

The electron released then undergoes inelastic scattering generating a shower of electric charge in its track.

The 3D printed MOF/ACNO/Graphene Supercapacitor then stores the generated charge for later use. Due to this feature, NDB is a graphene battery technology as well as a nuclear battery."
