BV100 (battery)

History

2025: Start of Production

In early April 2025, it became known that the Chinese company Betavolt New Energy Technology has created a new modular nuclear battery that uses a combination of the radioactive isotope nickel-63 and a fourth-generation diamond semiconductor. The novelty received the designation BV100. It is argued that smartphones with such power supplies will never need charging.

According to the resource New Atlas, the design of the presented element provides for the presence of two single-crystal diamond layers with a thickness of 10 microns each. Between them there is a layer of nickel-63 with a thickness of 2 microns. Each of these sandwiches is capable of generating current, but to improve efficiency, they can be connected like conventional electroplating cells.

The battery BV100 measures 15 × 15 × 5 mm. It is capable of generating 100 microwatts at 3 V. The module is enclosed in a case that protects it from radiation and physical damage. According to the developer, the energy density of the new power source is ten times higher than that of traditional lithium ion batteries. At the same time, atomic batteries are not susceptible to fires or explosions. In addition, the power supply BV100 generates energy, and does not accumulate it, due to which it does not lose capacity due to charging cycles during operation.

It is expected that mobile gadgets equipped with new nuclear batteries will not have to be charged at all. And a small drone with such a power source will be able to stay in the air for unlimited time. As of April 2025, Betavolt New Energy Technology is launching mass production of new items. In addition, work is underway to create a more powerful version of the power supply - per watt.^[1]
