If you didn’t know that the ‘battery revolution’ was upon us, then let Tesla’s announcement of its plan to build a multi-billion dollar battery factory be your wake up call. The lithium-ion batteries that are in our always-on phones are now moving to cars, as movement away from non-renewable resources grows.
Although this push for longer-lasting, more efficient batteries is the next logical step in the world’s dependency on energy everywhere, 24/7. But I think the inevitable next step after “super” batteries would be no batteries at all, via wireless charging. Let me explain a little more.
There is a company that is keeping its technology close to the vest about wireless charging, a company called uBeam (there’s not much to the site). They’re aiming to build new infrastructure and networks that work much like cell towers and cell signals work today. Except they’d be emitting a certain frequency that a special sensor in your device can detect and initiates a charging-like actions. So batteries wouldn’t necessarily go away, but you’d be less tied to your power cord and a wall.
It makes sense that they may roll out an “in-house” product first, so you can wirelessly charge items in your house (and keep them charged, even with a weaker battery). At that point, a high-end battery would be rather useless if you could essentially be “plugged into the wall” 100% of the time.
