So you feel pretty smug that you have a portable battery pack to power up your depleted smartphone during a particularly gruelling day at work? Well, here’s news for you – how about a smartphone battery that does not require any charging – or changing, for that matter, for up to 20 years. This is made possible thanks to the wonders of nuclear fission, but it is safe to assume that the majority out there would be aghast at carrying radioactive material in their pockets. The thing is, a Chinese website is said to carry a “20 Years Non-Stop Non-Charging Nano-Tritium Nuclear Battery” that retails for a whopping $1,122 after conversion.
The active material in these batteries would be tritium, and it is claimed that radiation caused by the decay of tritium is deemed safe, and unable to penetrate even the outermost layer of skin. For those wearing watches that glow in the dark, it is radioactive tritium in action there, so fret not with this City Labs-designed battery. City Labs claim that this battery can withstand a temperature range of -50℃ to 150℃, in addition to shrugging off extreme vibrations and altitude changes. Needless to say, not having to charge your phone ever is great, but what happens in a few years’ time when the smartphone landscape changes, and this battery is no longer compatible with the newer generation of devices?
