It’s already Saturday, I was worried there won’t be the weekly fix of miracle battery news incoming. What a relief!
Nickel 63 has a half life of 100 years. So that means you have safely store these things for 500 years after using them. Yeah, sounds totally fine.
Sounds very similar to the old Soviet pacemakers with radioisotope batteries. After the collapse of the Soviet Union, records about them got lost and so a bunch of people have been buried with pretty radioactive stuff in their chest. I don’t think we (as developed societies) are going to take that risk for some phone batteries…

Not unless it’s profitable, at least…
Can I just store it in the river behind my house?
That’s bad for the environment. You have to send them down the garbage disposal first!
A 50 year, nuclear, 100 MICROwatt battery. But sure. Will def get approved.

Yup. Not for phones, but maybe something that doesn’t require much power, and would benefit from a very long battery life.
Maybe things like doorbells in situations where connecting them to mains electricity is too cumbersome a process.
Or fire alarms. I know of a couple of foolish people who, when the batteries died, they didn’t bother putting new ones in.
There are lots of possibilities for this type of battery.
Is that even enough for a single LED to turn on?
“it says can keep a device charged for 50 years.”
On a device that gets replaced every 1-3 years? 🤔
Better be user replaceable or that’s a lot of energy being stored in landfills.
Turning every landfill into a fission reactor is certainly one way to fix the landfill issue
Would be cool for long term, low power devices like sensors embedded in concrete in bridges and building structures for monitoring stresses.
Make devices BYOB (Bring Your Own Battery)
Wait a minute. Are you telling me that this sucker is nuclear?
It’s too late for mobile devices. Everybody expects a permanent internet connection, either WiFi or mobile internet, and therefore they all need much more than some microwatts.
However, medical implants seem appropriate.
The nuclear battery for a phone would be larger than the one in the article and likely paired with a capacitor battery. So the nuclear battery is constantly outputting 1w to a capacitor that stores energy that the device draws from.
Phones don’t use tons of power constantly and the standby power needs are fairly low.
Just calculate an average day’s energy example. Let’s say, you charge your 5000mAh battery once per day from “10%” 2,6V to “100%” 4,2V. That makes about 8Wh. So your average for the whole 24 hours is 0,3 W, or 300 mW or 300.000 μW.
This sounds too good to be true.
I can’t believe it’s not butter
