It is demonstrated that 3D nanostructured polypyrrole (3D PPy) nanocomposites can be reinforced with PPy covered nanocellulose (PPy@nanocellulose) fibres to yield freestanding, mechanically strong and porosity optimised electrodes with large surface areas. Such PPy@nanocellulose reinforced 3D PPy materials can be employed as free-standing paper-like electrodes in symmetric energy storage device...

Potential applications of sodium-ion batteries in grid-scale energy storage, portable electronics and electric vehicles have revitalized research interest in these batteries. However, the performance of sodium-ion electrode materials has not been competitive with that of lithium-ion electrode materials. Here we present sodium manganese hexacyanomanganate (Na2MnII[MnII(CN)6]), an open-framework ...

In the search of new materials for future generation Li-ion batteries, a look into past has brought multicationic oxide Rb2TiNb6O18 to foreground. Structural characterization this material been carried out thanks combination XRD, SEM and HRTEM highlighting complex structure material. Ion exchange was performed in order replace rubidium ions by hydrated protons. Then, comparative study obtained ...
