Under the guidance of Betavoltics
a new nuclear battery is being manufactured at the University of Rochester. The nuclear battery operates off
of radioactive decay and should last the user more than a decade without being recharged.
A new type of battery based on radioactive decay of nuclear material is 10 times more powerful than similar prototypes and should last a decade or
more without a charge. The longevity would make the battery ideal for use in pacemakers or other surgically implanted devices, developers say, or it
might power spacecraft or deep-sea probes. You might also find these nuclear batteries running sensors and other small devices in your home in a few
The batteries are being developed at University of Rochester and the technology has been licensed by BetaBatt Inc. The technology, called
betavoltaics, uses a silicon wafer to capture electrons emitted by a radioactive gas, such as tritium. It is similar to the mechanics of converting
sunlight into electricity in a solar panel.
Betavoltaics has previously been unable to match solar-cell efficiency because when the gas decays, its electrons shoot out in all directions, causing
many of them to be lost. Electrical engineers took the flat silicon surface, where the electrons are captured and converted to a current, and turned
it into a 3-D surface by adding deep pits. Each pit is about one micron wide. That's four ten-thousandths of an inch. They're more than 40 microns

Engineers are aiming for ways to improve the manufacturing process in order to make an even more efficient design. We should see nuclear batteries
powering our Mp3 and digital cameras within the next five years.
Guess we can start getting rid of those Duracells and Energizers.
