Coin-sized nuclear 3V battery with 50-year lifespan enters mass production
-
100 microwatts
This is a very important spec to include...this battery can deliver 0.003mA of power, which is incredibly little.
this battery can deliver 0.03mA of power
0.03mA of current. That times the 3 volts = 0.1 mW of power.

CR2032s are used in many things that require significantly more power than that, and this cell is absolutely unfit for almost all other uses than barebones old school digital watches.
Sure. I'm not saying it's a drop-in replacement, just that it has a number of applications. A simple digital watch or even a bare bones IOT device (with periodic serial signaling) could work well with it. You'd essentially set it up once and you'll forget it's still there many years later.

Are these ones ocean disposable like lead acid batteries?

yay nuclearwaste for everybody 🥳
The radioactive nickel decays into stable copper and has a half life of 100 years. Not really 'waste'

Technology Connections, we need you to make another video.

These aren't new.
They have tiny current output. Only suitable for a few niche applications. The company's claim to fame is making them cheaper, but don't expect much.

what kind of things could you power with that amount?
An RTC that you want to leave on its own for a very long time. Like underwater.

Read the article guys, yes it is extremely low amperage how ever they are meant to be used in parallel, as you would expect, you use this right now in real life applications I don’t see the niche part but 5 cels the size of a nikle can power most iot micro nodes.

I was concerned about what happens when someone accidentally throws away a device with a fresh battery, but this:
The BV100 harnesses energy from the radioactive decay of its nickel-63 core. The two-micron thick core, sandwiched between two 10-micron thick diamond semiconductors
makes me feel a bit better. That really isn't much radioactive material. Still, it'd be good to see some environmental impact studies done in some worst case scenarios.
It has to be. Making a big one is effectively impossible, the amount of shielding needed goes up much faster than the amount of radioactive material used.

These types of batteries are called wafer batteries because you just eat them

Someone's gotta charge the eels.

This is wild; the battery would outlive the electronics it's powering in almost all cases.
The output is incredibly tiny, but I wonder if it could be used to trickle-charge a higher-output battery for use in electronics that only need to be used infrequently for short durations.
It's becoming quite rare to change the CR2032 on a PC motherboard these days. Even those tend to outlive the hardware.

It's wafer thin
