On-chip interdigitated supercapacitor based on nano-porous gold/manganese oxide nanowires hybrid electrode

Facile fabrication of all-solid-state flexible interdigitated MnO2 supercapacitor via in-situ catalytic solution route

“…In summary, as we can conclude from the Ragone Plot of Fig. 7e, our PET/Pt/MnO 2 flexible SCs exhibits excellent performances not only in the category of energy storing but also charge and discharge, compared with SC of traditional electrode structure like Ag nanowire/PEDOT/PSS-nanopillar/ MnO 2 sandwich-type flexible SC [55], this is because that interdigitated type is benefit for ion diffusion and electron transportation during the charge and discharge process compared to traditional sandwich type under the circumstances of the same electrode materials system of metal/MnO 2 [60]. When compared with some SCs which obtains the same interdigitated structure, for example the work of Wen et al [56] and Shen et al [59] shown in the Fig.…”

A Highly Durable, Transferable, and Substrate‐Versatile High‐Performance All‐Polymer Micro‐Supercapacitor with Plug‐and‐Play Function

“…[1] On the other hand, the microfabrication technology opens up the possibilities for fabrication of microenergy-storage-devices with planar interdigitated structure. [20][21][22][23][24][25] Conductive polymers after being doped, advantageous to other pseudocapacitive materials (metal oxides), [26,27] offer low cost, high conductivity, lightweight, and excellent flexibility. Although these μSCs show excellent energy-storage performance (e.g., excellent power density and long cycle life) and great feasibility to be integrated to miniaturized devices, the usage scenarios are still limited due to the following disadvantages.…”

On‐Chip Microsupercapacitors: From Material to Fabrication

“…This hybrid MnO 2 /NPG MSC exhibited ultrahigh performance with an energy density of 12.7 mWhcm −3 and power density of 46.6 Wcm −3 , which was comparable with commercial thin‐film Li‐ion batteries and carbon‐based MSCs . Meanwhile, by using NPG and manganese oxide nanowires hybrid electrode, the two densities change to 50 mWhcm −3 and 3.4 Wcm −3 . The difference may be attributed to the different nanostructures of MnO 2 .…”
