Up and atom: How exactly does a ‘forever’ battery work?

They are small, nuclear, and will never need to be charged. But what are they likely to cost? What will their carbon footprint be? Take a look.

How the world changes… The technology that powered the nuclear bomb may soon be so tamed, it will sit in palms and laps, powering phone and laptop batteries so effectively that they may never need to be charged.

Radioactive materials such as nickel-63, which has a half-life of about 100 years, could power a personal device for as much as half a century, manufacturers have said.

How would this futuristic tech work? Let’s first take a quick look back.
