A well-designed hierarchical nanostructure composed of NiMn-layered double hydroxide (NiMn-LDH) microcrystals grafted on a carbon nanotube (CNT) backbone is constructed by M. Wei and co-workers using an in situ growth route, which shows superior supercapacitive performance. On page 2938, an all-solid-state asymmetric supercapacitor (SC) with good flexibility is fabricated using the NiMn-LDH/CNT film and reduced graphene oxide (RGO)/CNT film as the positive and negative electrodes, respectively.
