Based on the search results provided Perplexity AI , it appears that a Chinese startup called Betavolt has developed a revolutionary new type of battery that can power smartphones for up to 50 years without needing to be recharged. Here is a summary of the key details:

Betavolt’s 50-Year Nuclear Battery

• Betavolt has developed a miniature “nuclear battery” that uses the radioactive decay of nickel-63 isotopes to generate electricity12345.
• This battery, called the BV100, can provide power for up to 50 years without needing to be recharged12345.
• The battery is very small, measuring just 15x15x5 cubic millimeters, about the size of a coin345.
• It has an extremely high energy density, able to store 3,300 megawatt-hours in just 1 gram of material – over 10 times more than a typical lithium-ion battery345.
• The battery is also very safe, as it will not catch fire or explode even if punctured or exposed to high temperatures45.
• Betavolt plans to release a 1-watt version of the battery in 2025, which could potentially power a smartphone indefinitely without the need for charging345.

In summary, Betavolt’s revolutionary 50-year nuclear battery has the potential to completely transform the smartphone industry by eliminating the need to constantly charge devices. This breakthrough technology could make it possible for phones to operate continuously without any battery degradation over decades of use
