Stretchable energy storage and conversion devices
Stretchable electronics are a type of mechanically robust electronics which can be bended, folded, crumpled and stretched and represent the emerging direction towards next-generation wearable and implantable devices. Unlike ...
Green synthesis of nanobelt-membrane hybrid structured vanadium oxide with high electrochromic contrast
Vanadium oxide with a nanobelt-membrane hybrid structure is synthesized under the structural directing effect from tannic acid, a green extract from plants. The electrochromic property of the resultant film was investigated ...
Hollow LiMn2O4 nanocones as superior cathode materials for lithium-ion batteries with enhanced power and cycle performances
Single-crystalline LiMn2O4 hollow nanocones are synthesized via a template-engaged low-temperature lithiation reaction. When applied as cathode materials for lithium-ion batteries, they can deliver a high specific capacity ...
Nickel cobalt oxide nanowire-reduced graphite oxide composite material and its application for high performance supercapacitor electrode material
In this paper, we report a facile synthesis method of mesoporous nickel cobalt oxide (NiCo2O4) nanowire-reduced graphite oxide (rGO) composite material by urea induced hydrolysis reaction, followed by sintering at 300 °C. ...
