Radioactive diamond nanobatteries will last up to 28,000 years

Radioactive diamond nanobatteries will last up to 28,000 years

Scientists want to use batteries with a service life of 28,000 years to power smartwatches, for example. Behind the idea are people associated with the Nano Diamond Battery Company.

Already last year, this American company announced the results of a potential pilot study, which showed that nano diamond batteriesOn the basis of nuclear waste can last up to 28,000 years. According to NDB representatives, their project will lead to the creation of high-energy diamond, photovoltaic and petavoltaic batteries.

Such long-lasting batteries can find a variety of applications. This includes powering miniature devices, such as starters, as well as larger devices, such as Mars rovers. Among the advantages of their project, its authors mentioned scalability. Adding a few cells could make batteries – rather than small gadgets – able to power devices that require higher power.

The Nano Diamond Battery radiant batteries can power small and large appliances

The Nano Diamond battery is made of layers of very small diamonds, the size of which is measured in billionths of a metre. Because diamond has a high thermal conductivity, it is great for electronics design. At the same time, it is three to four times more effective than copper or silver. A phenomenon known as chemical vapor deposition plays a major role in the formation of these nanodiamonds. However, this makes production time-consuming and expensive.

It is then combined with the radioactive isotopes from the nuclear waste. The radioactive isotopes of uranium and plutonium allegedly come from nuclear power plants. When these isotopes decay, the resulting energy goes to the NDB converter, which converts kinetic energy into electricity. Efficiency appears to be the biggest issue in this case, as a single battery cell will produce a small amount of power, so it must be connected, which in turn increases production costs.

Moreover, we must not forget that batteries that are produced from nuclear waste can themselves become nuclear waste. As a result, the Earth can become polluted with huge amounts of radioactive tiny batteries. In the case of Mars, it may not be a problem, but on our planet – by all means. This indicates that the solution proposed by the Nano Diamond Battery could be great for space exploration. They can command or use Earth-orbiting satellites during missions on the Moon, Mars, or other things in the Solar System…or beyond.
