Power dense zinc-manganese power unit as cheap as a car battery

A team of scientists working on analyzing energy flows in prototype zinc-manganese batteries have stumbled upon a new way to make these power cells much more reliable, with many more recharge cycles than the humble lead-acid car battery, but costing around the same to produce. The creators claim that the new battery could become an inexpensive, ecologically-sound alternative for storing energy from renewable sources and a high-density solution for storing excess energy from the power grid.Read More

Nanowire battery electrode powers through hundreds of thousands of charge cycles

With high conductivity and a large surface area, nanowires have become quite the candidate for an advanced battery material. But at thousands of times thinner than a human hair, their delicate nature often causes them to fracture throughout the battery cycle. By designing a nanowire-based electrode with a special protective coating, researchers now claim to have overcome this limitation, which could lead to batteries able to withstand hundreds of thousands of recharge cycles.Read More

Super-thin iPhone case hides extra juice

While there are many battery back-up iPhone cases out there, they all tend to add significant weight and thickness to your otherwise sleek smartphone. The Air Case, now at the start of a so-far successful Indiegogo campaign, aims to change that by packing some decent juice into a case that's really no bigger than a standard protective wrapper you might put on your phone anyway.Read More
