Abstract: We apply in situ transmission electron microscopy (TEM) and lab-on-a-chip to mechanistic investigations of energy nanomaterials. Recent advances in nano-manipulation, environmental TEM and MEMS have allowed one to investigate coupled mechanical and electrochemical phenomena [Nano Letters 15 (2015) 1302; Nano Letters 15 (2015) 1437] with unprecedented spatial and temporal resolutions. We can now quantitatively characterize liquid-solid and gas-solid interfaces at nanometer resolution for in situ oxidation, fatigue and hydrogen damage [Nature Materials 14 (2015) 899] processes. Direct observations of SnO2, ZnO, Si, Ge, graphene and carbon nanotube battery anodes and LiFePO4 nanowire cathode [Nano Letters 14 (2014) 4005] have been performed. I will also discuss about scalable synthesis of high-capacity and high-rate anode (aluminum, silicon @ titania yolk-shell nanostructures [Nature Comm. 6 (2015) 7872]) and cathode (sulfur with carbon black [J. Mater. Chem. A 2 (2014) 19788], lithium sulfide with graphene paper [Nano Letters 15 (2015) 1796]) and supercapacitor materials.
