Future batteries, coming soon: Charge in seconds, last months and power over the air
While smartphones, smart homes and even smart wearables are growing ever more advanced, they're still limited by power. The battery hasn't advanced in decades. But we're on the verge of a power revolution. Big technology and car companies are all too aware of the limitations of lithium-ion batteries. While chips and operating systems are becoming more efficient to save power we're still only looking at a day or two of use on a smartphone before having to recharge. While it may be some time before we get a week's life out of our phones , development is progressing well. We've collected all the best battery discoveries that could be with us soon, from over the air charging to super-fast 30-second re-charging. Hopefully, you'll be seeing this tech in your gadgets soon. Capturing energy from Wi-Fi While wireless inductive charging is common, being able to capture energy from Wi-Fi or other electromagnetic waves remains a...
