Nanowire Electrodes for Electrochemical Energy Storage Devices

Rationally Designed Silicon Nanostructures as Anode Material for Lithium‐Ion Batteries

“…[34,93] Since firstly reported in the early 1960s, tremendous methods have been explored to synthesis Si NWs with controllable diameters and lengths, which can be classified into two categories: direct growth techniques and etching techniques. [94][95][96] The vapor-liquid-solid (VLS) method is the most common way of growth method and it is first proposed by Wagner and Ellis in 1964.…”

“…Among them, the most efficient way is combining Si with other nanowireconstructed matrix forming mixed anode material, such as C, Cu, Ni, Co. [15,93,102] Wang et al reported an exceedingly crosslinked Cu/a-Si (amorphous Si) NWs hybrid electrode, where the rational designed Cu cores served as a highly conductive matrix enabling fast electron transport and preserved the structural integrity during repeated cycling. [103] The fabrication procedures are presented in Figure 8a-f, which can be roughly divided into two approaches: the chemical synthesized process of Cu-based substrate and the depositing process of Si by PECVD method.…”

Track batteries degrading in real time

“…This will speed the development of monitoring techniques such as in situ X-ray and Raman spectroscopy, as well as the commercialization of electrodes and batteries based on nanomaterials. For example, Wuhan University of Technology in China and Harvard University in Cambridge, Massachusetts, are collaborating on designing innovative devices 3,5 .…”

“…Improved lithium-ion batteries have extended the mileage of electric cars from about 150 kilometres in 2012 to more than 500 km today, for Tesla's Model S 100D. Yet lithium-ion batteries remain expensive (US$250 per kilowatt-hour) 1 and of limited efficiency (200-250 watt-hours per kilogram) 2,3 .…”

Graphene Oxide Wrapped Amorphous Copper Vanadium Oxide with Enhanced Capacitive Behavior for High‐Rate and Long‐Life Lithium‐Ion Battery Anodes

“…The ever‐increasing consumer market has stimulated the expansion of lithium‐ion batteries from energy storage devices to up‐coming electric vehicles 1, 2, 3, 4. To build a better battery, several factors should be taken into account, including energy density, rate capability, cost, safety, and sustainability 5, 6, 7, 8, 9, 10.…”
