The Radioactive Diamond
Battery That Will Run For 28,000 Years
A U.S. startup combined radioactive isotopes from nuclear waste
with ultra-slim layers of nanodiamonds to assemble a ridiculous battery that
allegedly can last 28,000 years.
According to the California startup in question, called NDB (Nano Diamond Battery), their product is a
“high-power diamond-based alpha, beta, and neutron voltaic battery.”
Diamond
batteries are forever
The energy comes from waste graphite that was previously used in
graphite-cooled nuclear reactors. The radioactive graphite is encased in layers
of nano-thin, single crystalline diamond, which act both as a semiconductor and
heat sink.
Diamond is the hardest material known to man. It also has the
highest energy-conductivity, meaning it quickly transfers heat from the
radioactive graphite. So the diamond layers not only collect charge, but also
prevent radiation leakage.
Since the carbon-14 isotopes have half-life times in the
range of thousands of years and diamonds are virtually indestructible, NDB felt
confident making this bombastic marketing claim.
“This battery has two different merits,” NDB CEO
and co-founder Nima Golsharifi said in an interview with Future Net Zero. “One is that it uses nuclear waste and converts it
into something good. And the second is that it runs for a much longer time than
the current batteries.”
he product is supposed to come in two versions. The “forever”
version that is supposed to last 28,000 years before it runs out of charge.
This hard-core version is meant for niche applications, such as deep space
where it could power instruments onboard spacecraft and satellites. These
spacecraft, for instance, could be sent to other star systems on centuries-long
voyages and they would still have enough power to beam back messages.
There is also a consumer version, meant for powering electric
vehicles, smartphones, and other small devices. Since the graphite would be
wrapped in multiple coatings of synthetic diamond, there would be no radiation
leaking out of your phone. NDB even claims that the radiation levels emitted by
the cells will be less than those emitted by the human body.
That may or may not be true, but frankly, it would be interesting
to see who would buy a product fully aware that it contains a radioactive
battery.
The charge collected by battery cells is collected, stored, and
instantly distributed by a supercapacitor. Cells can be built to conform to any
shape or standard, including AA, AAA, 18650, 2170, or all manner of custom
sizes.
For now, NDB has only completed a proof of concept. The company was
about to release a commercial prototype, but then came COVID. Nevertheless, the
company expects to release a low-power commercial version of its radioactive
diamond battery in less than two years, while the high-power version is slated
for five years’ time.
