An aluminum graphite bat...
Smartphones are pretty amazing devices, but their most vexing problem remains battery life. No matter how power efficient the hardware gets, manufacturers end up using all of it and more for improved displays, faster performance, and more features. Now scientists at Stanford University may have come up with what is nothing short of the Holy Grail for mobile devices: an ultra-fast-charging aluminum battery that could be produced on a mass scale.
