Reasearchers at the Center for Integrated Nanotechnologies (CINT) claim to have created the tiniest battery in the world.The rechargeable , lithium-based battery was developed by a team led by researcher Jianyu Huang. The battery comprises a 3mm long lithium cobalt cathode, a single tin-oxide nanowire anode and an ionic liquid electrolyte.The anode , which measures 10 nanometres in length and 100 nm in diameter, is one seventhousandth the thickness of a human hair. A lithium-ion battery with nanowire-based materials greatly increases the power and energy density compared to one using bulky electrodes.Researchers developed this battery in order to better understand the mechanism in which it works and formed the battery inside a transmission electron microscope that would enable them to study charging and discharging of the battery in real time and at atomic-scale resolution
