A Nuclear Powered Battery,

that is smaller than a coin in size but has a lifespan of around 50 years and does not require recharging,

images Betavolt, a atomic battery sounds, 'A' a bit dangerous, and 'B' too good to be true! both the United States and the USSR produced atomic batteries during the 1960s, but these nuclear batteries were large, dangerous, and expensive to make, but science has come on a tad, Betavolt’s revolutionary battery now relies on a much safer isotope, nickel-63, which decays to a stable isotope of copper, so that is 'A' out of the way, 

so what about 'B', too good to be true? Apparently it is true, measuring just 15mm x 15mm x 5mm, the new Betavolt BV100 constantly generates electricity as the isotopes degrade, unlike conventional batteries which simply store energy, the company plans to begin mass-producing the battery later this year, and introduce a more powerful version in 2025, the BV100 is considered a breakthrough on many levels, but as several tech news outlets point out, the power output of 100 microwatts at 3 volts isn’t particularly impressive, but Betavolt plans to launch a new 1-watt atomic battery in 2025, and as technology improves, we may soon see smartphone batteries that require no recharging or replacing, I wonder if the powers that be in mobile telephone companies will ever let that happen? the article is here.
