WIRED: The explosive race to totally reinvent the smartphone battery

Description

At the University of Manchester, materials scientist Xuqing Liu is among those trying to squeeze more life out of the carbon anode, by incorporating 2D materials similar to graphene that can grow the surface area, and therefore boost the number of lithium atoms it can hold. He likens it to increasing the number of pages in a book. The university is also investing in a dry room which will allow it to safely and easily swap different components to test different combinations of electrodes and electrolytes.
