Ich hoffe wirklich, dass es keine Klick-Köder-Vaporware ist, weil ich mir mehrere Verwendungszwecke für diese vorstellen kann.

China, so it might not be a joke, just a standard lie.
Article states that „A Chinese battery manufacturer has developed a breakthrough, sparking a worldwide race for compact nuclear energy. The innovation is a small coin-sized battery powered by a radioactive nickel isotope that decays into stable copper. While the initial cell is relatively weak, it can easily be layered to provide more power for up to 50 years.“
I haven’t found a hint on cost.
Amperage? My understanding is that the power density is really low despite the energy density being very high.
*Looks at calander* remind me in a few days if its not some April fools thing
If this isn’t an April Fools joke, it would be interesting, especially with their 1 watt version that’s slated to be released later this year. That’s enough to trickle charge a phone enough to counter idle power loss.
I remember a classmate in college coming in so excited about this technology. That time it was a nuclear laptop battery that would never need to be charged. She posted fliers about it all over our wing.
That was 20 years ago. Still waiting on these magical batteries, that will melt your device before it charges it, to actually appear on the market.
This is both vaporware and not vaporware.
Beta voltaics nuclear cells have been around for half a CENTURY. They’re nothing new. They’re not revolutionary, they’re not the perfect energy source. They output MINUSCULE amount of power, 0.1 mW in this case, and their conversion efficiency is garbage since it’s less than 3%.
But this product is real and this company actual achievement seems to be being able to produce them at large scale and relatively low price. This could mean cheaper implantable peacemaker, mostly, since it’s what these cells are mostly used today.
Just as comparison, TEG Peltier modules are known to be have a terrible efficiency and they still manage 3 times what beta voltaics manage on average.
This is still early stages for this technology. I suspect that in 2-5 yrs it will advance from an early stage curiosity to functional use in modern electronics. And costs will decline accordingly.
What is very attractive is the decay into non radioactive form.
I am curious as to the energy drop off towards end stage life.
