      It’s not that radioactive and Nikel 63 decays to copper, so there is no radioactive waste being produced when the battery is depleted.

    Oh, good. So whenever some fool tosses a phone out of a car to get crushed on the roadway, shoots one because TikTok, or otherwise mangles a phone, we now have a potential for radioactive material to be spread around?

      No, read the article. It’s Nikel 63 and the decay is copper. It’s contained in a metal seal.

      The size is smaller than a coin. Put enough of them in parallel and they’ll output enough power.

        Yeah 5000 of them to get the 500 mW a smartphone needs in standby mode. 50000 if you want to power up the phone from stabdby (assuming it just uses 5 Watts)

        It is the article that mentioned smart phones which is bullshit. This is a (probably expensive) battery specialized for extremely low power devices which need to run for many years. It will never be something that powers your phone.

        The tech is really cool and there’s applications for such a battery - just not phones.

          A lot of sensors/gauges in industrial applications are retrofitted with lorawan or similar remote readout capabilities right now. Battery life for these devices is already a big design consideration, especially since not all locations are easily accessible.

          With a power source like this you would essentially charge a capacitor, use the stored charge to do a sensor read and short data burst, and then wait for the next charge.

          They could eventually raise power levels. The tech can be further researched. We didn’t come to this Li-Ion battery capacity with no research.

    100 microwatts? What does a phone use, like 1W? So they are 4 orders of magnitude off? So phones need to become 10,000 times more efficient or the battery that much bigger?

    Edit: Also what is the language of the article? “63 nuclear isotopes”, it sounds like they mean “63 [different/individual atoms of] nuclear isotopes” but do they mean “nickel-63” by this? It is very confusing. Nickel-63 also has a half-life of 100 years, so if the battery is supped to last for 50 years, it has to be producing twice as much energy on day one that is discarded?
