Pyridinium electrolytes are promising candidates for flow-battery-based energy storage1,2,3,4. However, the mechanisms underlying both their charge–discharge processes and overall cycling stability remain poorly understood. Here we probe the redox behaviour of pyridinium electrolytes under representative flow battery conditions, offering insights

Weakly coordinating anions (WCAs) are used throughout chemistry to minimise cation-anion interactions in the solid and solution states. The ability to suppress ion-pairing has important bearings – or impacts on the properties of materials, on single-site catalysis and on ionic

To help ensure a prosperous future on Earth for coming generations, academia and industry need to transform the way they plan and carry out the synthesis of novel materials to make them more environmentally sustainable. In particular, the field of

Hard carbons are the most suitable anode materials for practical sodium-ion batteries (NIBs). Despite various studies, there is still significant scope for improvement in the understanding of the (de)sodiation mechanisms. Here, we study Sn incorporation in waste derived commercial and

The iron-based polyanionic fluoro-oxalate material, KFe(C2O4)F (KFCF), has been synthesized by hydrothermal methods. This compound shows promising reversible lithium and sodium insertion properties as a cathode material. The material delivered a first-cycle discharge capacity of 120 mAh g−1 at ∼3.3 V (Li+/Li) and

Sodium ion batteries represent a sustainable alternative to Li-ion technologies. Challenges with material properties remain, however, particularly with regards the performance of anodes. We report a rapid, energy-efficient ionic liquid synthesis method for mixed phase Na2Ti3O7 and Na2Ti6O13 rods. This

Sodium-ion batteries have attracted widespread interest due to the potential for providing safe and cheap energy storage. However, large scale use of sodium-ion batteries is limited by insufficient performance from positive electrode materials, while also avoiding the use of expensive
