Can you imagine an everlasting battery powering your smartphone?

This Chinese company claims its nuclear battery will be able to power your phone for 50 years.

Creating an everlasting battery is the oldest dream of mankind, along with a perpetual motion machine. Well, or at least one that would work without recharging for years, many years. Research centers around the world and technology corporations are working to create better battery materials and a completely new type of electrolyte for a new generation of lithium metal batteries that would allow them to last much longer than the lithium-ion batteries we use now. For example, recently engineers from Brown University and Idaho National Laboratory proposed a new nanostructure for the electrolyte of the future, and they were inspired by the principle of operation of simple and familiar soapy water that cleanses dirt and grease.

At the same time, a much more ambitious concept for the battery of the future is being developed in China. The Chinese company Betavolt announced that it has created a nuclear battery for electronic gadgets that will work for 50 years without the need for recharging. This battery is a tiny plate containing 63 nuclear isotopes, the movement of which converts nuclear energy into electrical energy. According to company, the first battery model can provide 100 microwatts of power and 3 volts, enough for digital watches and other mini devices.

The first Betavolt battery, serially named Model BV100, can operate at temperatures ranging from minus 60 to 120 degrees Celsius. By 2025, the company plans to create a more powerful 1 W battery that can power smartphones and even drones. "Betavolt nuclear batteries can meet long-term power supply needs in a variety of scenarios such as aerospace, artificial intelligence equipment, medical equipment, microprocessors, advanced sensors, small drones and micro-robots," Betavolt promises.

The question that all potential users of such a battery will certainly ask is: isn't it dangerous to keep a nuclear battery in your pocket? Betavolt assures that its batteries fully meet safety requirements and are absolutely harmless to humans. Its safety is ensured by the fact that after a period of decay, the 63 isotope turns into a stable isotope of copper, which is non-radioactive and does not pose any threat of environmental pollution.
