Arrays of ultrafine CuS nanoneedles supported on a CNT backbone for application in supercapacitors
Arrays of CuS ultrafine nanoneedles supported on a carbon nanotube (CNT) backbone (CNT@CuS) are fabricated by an efficient template-engaged chemical conversion route. First, the silica coated CNTs (CNT@SiO2) are introduced ...
Facile preparation of ZnMn2O4 hollow microspheres as high-capacity anodes for lithium-ion batteries
Uniform ZnMn2O4 hollow microspheres have been synthesized by a facile coprecipitation and annealing method. The resultant ZnMn2O4 hollow microspheres exhibit high specific discharge capacity, good rate capability, and ...
