Approaching high performance Ni(Co) molybdate electrode materials for flexible hybrid devices.

Transition metal molybdates are widely used as electrode materials for supercapacitors due to their high theoretical specific capacitance and excellent electrochemical activity. It is an effective strategy to improve the electrochemical performance by reasonably designing electrode materials. Herein, we prepared several Ni Co MoO·HO nanostructures through facile hydrothermal strategies.

Realizing high performance flexible supercapacitors by electrode modification.

It is well known that the structure of an electrode material seriously affects its electrochemical performance. In this study, we prepare hybrid structured NiCoS@PPy nanoarchitectures by a hydrothermal method and subsequent electrodeposition process. The specific capacitance of the obtained sample is 1733.

A flexible hybrid capacitor based an NiCoS nanowire electrode with an ultrahigh capacitance.

It is well-known that the excellent cycling stability and high energy density of electrode materials is very important for supercapacitors. However, their actual performance falls far behind and does not satisfy the practical demand. In this study, we synthesized NiCoS nanowire bundles on a nickel foam via facile hydrothermal routes.

Transition metal oxide@hydroxide assemblies as electrode materials for asymmetric hybrid capacitors with excellent cycling stabilities.

In this work, three-dimensional cactus-like CoO@Ni(OH) electrode materials are grown directly on Ni foam a two-step hydrothermal method. The as-prepared products possess a specific capacitance of 464.5 C g at 0.
