A micro-battery could change all of that. The first cell phone, or what we might recognize as a mobile phone, was produced in 1973 by Motorola, weighed 40oz and took […]

Present in almost any device from earpieces to electric cars, there is a need to use them in micro- or nano-sized devices. A DARPA-funded project aims at creating the smallest lithium ion batteries ever, as small as a grain of sand.
