Abstract A facile chemical reduction method for preparation of Co Ni B was designed and developed. The obtained products showed outstanding electrochemical performances as positive electrode materials in aqueous electrolytes at different current densities (from 1 A g −1 to 20 A g −1 ). Co Ni B nanocomposite exhibited reversible specific capacity of 319.4 mAh g −1 , remarkable rate capability over 90% at 20 A g −1 , and excellent cyclability with no obvious decay over 100 cycles. The high surface...

Abstract The development of devices capable of generating energy through biofluids, such as sweat, is an effort to integrate flexible devices that can be powered and used on the skin. A patch-type completely enzymatic biofuel cell (p-EBFC) is developed using bilirubin oxidase- and lactate oxidase-based electrodes as biocathode and bioanode respectively, where both enzymes are immobilized on flexible Toray carbon paper-modified. The evaluation of the half-cells shows that the bioelectrodes had go...

Abstract The graphite as the potassium ion battery anode is studied in KPF 6 -EC/DMC and KPF 6 -DME electrolytes. It is found that the graphite demonstrates superior rate performance with a capacity of 87 mAh g −1 at a current rate of 10 C (corresponding to 2.8 A g −1 ) and excellent capacity retention ability of 84% after 3500 cycles in DME-based electrolyte. Moreover, its initial coulombic efficiency is 87.4%, higher than 69.6% in EC/DMC-based electrolyte. The K + solvating with DME complexes ...

Abstract Three-dimensional (3-D) interconnected porous Na 3 V 2 (PO 4 ) 3 coated with carbon (NVP@C) is synthesised by a simple modified sol-gel method. When 15 wt% glucose is used as the carbon precursor, the obtained NVP@C15 composite exhibits excellent electrochemical performance as a cathode as well as an anode for sodium-ion batteries (SIBs). As a cathode, the NVP@C15 electrode delivers a high capacity of 116.9 mAh g −1 at a rate of 1 C, which is close to its theoretical capacity. Even at a...

Abstract In-depth understanding of water management is essential for the optimization of the performance and durability of polymer electrolyte fuel cells (PEFCs). Neutron imaging of liquid water has proven to be a powerful diagnostic technique, but it cannot distinguish between ‘legacy’ water that has accumulated in the system over time and ‘nascent’ water recently generated by reaction. Here, a novel technique is introduced to investigate the spatially resolved water exchange characteristics in...

Abstract Antimony-carbon nanocomposites are known anode materials for lithium- and sodium-ion batteries that can display an attractively stable cyclic behaviour in half-cells. They can also be used for potassium-ion batteries but a similar stability is not achieved, and electrode failure (abrupt capacity decay) is noted. Here, we probe the failure mechanism in potassium cells using samples with varied Sb particle sizes and weight fractions. A smaller particle size and extra carbon result in a fa...

Abstract We use a redox mediator pair - hydroquinone (for positive electrode) and sodium anthraquinone-2-sulfonate (for negative electrode) - to treat the activated carbon electrodes for fabricating asymmetric supercapacitors. This simple adsorption-based treatment improves the specific capacity of the activated carbon electrode from 69.3 mAh g −1 to 300.4 mAh g −1 (negative electrode) and 63.5 mAh g −1 to 301.1 mAh g −1 (positive electrode). The charge balance between the two electrodes is achi...

Abstract Poly(arylene ether ketone)- g -poly(vinyl 1-butylimidazolium bis(flouromethyl sulfonyl) host polymer and 1-butyl-1-methylpyrrollidium bis(flouromethane sulfonyl) ionic liquid are synthesized. The host polymer is blended with ionic liquid to prepare the solid electrolyte membrane for lithium secondary battery. The solid electrolyte membranes integrated with ionic liquid show excellent properties in lithium ion conductivity, interfacial resistance, thermal and mechanical stability, depend...
