The BV100 micro nuclear energy battery is said to provide 100 mW at 3V continuously without recharge or any maintenance for 50 years. Despite using the radioactive nickel-63 isotope, the battery can safely power even pacemakers inside the human body and is environment-friendly as well.

Lithium polymer batteries have had quite the impact on many portable devices like phones and laptops in the past three decades. Depending on battery capacity and size, laptops can now operate more than 15 h and phones may last up to several days per single charge, plus there is support for rapid chargers that can fully recharge batteries in less than an hour. However, save for the new GaN chargers, the progress has been slowing down considerably in the Li-ion sector, as chip makers try to offer increased power efficiency through transistor miniaturization. China now intends to revolutionize this industry with a new type of battery that acts as a micro nuclear reactor promising to offer continuous power for 50 years.

Betavolt New Energy Technology Co., Ltd from China successfully developed a micro nuclear energy battery based on the nickel-63 nuclear isotope decay along with the first diamond semiconductor. The battery model is known as BV100 and it is said to generate electricity for 50 years without charging or maintenance. Considering that we now buy new devices every few years, even 2-3 years of continuous power should be sufficient. Betavolt plans to initiate mass production later this year.
