Chinese company develops ultra-compact nuclear battery that is the size of a coin and lasts for 50 years
China's Beijing Beitabute New Energy Technology Co., Ltd. announced that it has developed an ultra-small nuclear battery that measures 15 mm x 15 mm x 5 mm, which is even smaller than a 20 mm diameter 1 yen coin, and can supply 100 microwatts for 50 years. Betavolt Technology) announced.

The nuclear battery developed by Betavolt Technology combines nickel-63 isotope and China's first diamond semiconductor (4th generation) module. The idea of nuclear batteries itself was widely researched by the United States and the Soviet Union in the 1960s, but they were large, heavy, and expensive, and had many drawbacks, so they were mainly used for aerospace applications, and consumer products were not widespread.
Now, Betabolt Technology has created an independent modular unit by placing a 2-micrometer-thick nickel-63 thin film between two diamond semiconductors, effectively converting the decay energy of the radioactive nickel-63 into electricity. conversion. The battery itself has been significantly downsized while keeping production costs low.
The power generation capacity is 8.64 joules per day, or 3153 joules per year. Modular design allows multiple batteries to be combined for higher output.
The battery is already in pilot production and, subject to regulatory approval, the first products are expected to appear in 2025.
Betavolt Technology has obtained a patent for this technology in China, and is currently in the process of registering a PCT international patent . In addition, in cooperation with various research institutes and universities, they are aiming to develop batteries with a service life of 20 to 30 years using isotopes such as strontium-90, palladium-147, and deuterium.
