Self-Charging, Thousand-Year Battery?

Pleasanton-based green energy startup NDB, Inc. has reached a key milestone today with the completion of two proof of concept tests of its nano diamond battery (NDB) . One of these tests took place at the Lawrence Livermore National Laboratory, and the other at the Cavendish Laboratory at Cambridge University, and both saw NDB’s battery tech manage a 40% charge, which is a big improvement over the 15% charge collection efficiency (effectively energy lossiness relative to maximum total possible charge) of standard commercial diamond.

NDB’s innovation is in creating a new, proprietary nano diamond treatment that allows for more efficient extraction of electric charge from the diamond used in the creation of the battery. Their goal is to ultimately commercialize a version of their battery that can self-charge for up to a maximum lifespan of 28,000 years, created from artificial diamond-encased carbon-14 nuclear waste.

This battery doesn’t generate any carbon emissions in operation, and only requires access to open air to work. And while they’re technically batteries, because they contain a charge which will eventually be expended, they provide their own charge for much longer than the lifetime of any specific device or individual user, making them effectively a charge-free solution.

NDB ultimately hopes to turn their battery into a viable source of power for just about anything that consumes it — including aircraft, EVs, trains and more, all the way down to smartphones, wearables and tiny industrial sensors. The company is currently now at work creating a prototype of its first commercial battery in order to make that available sometime later this year.
