A new layered Na0.3MoO2 exhibits a reversible capacity of 146 mA h g−1, remarkable cycling stability and good rate capability for sodium half-cells. And a Na0.3MoO2//Na0.8Ni0.4Ti0.6O2 full intercalation-type sodium-ion cell is fabricated and it displays an excellent cycling stability. These results indicate that molybdenum-based oxide is a promising anode material for sodium-ion batteries.

Both the binder and solid–electrolyte interface play an important role in improving the cycling stability of electrodes for Na-ion batteries. In this study, a novel tetrabutylammonium (TBA) alginate binder is used to prepare a Na0.67MnO2 electrode for sodium-ion batteries with improved electrochemical performance. The ageing of the electrodes is characterized. TBA alginate-based electrodes are compared to polyvinylidene fluoride- (PVDF) and Na alginate-based electrodes and show favorable electrochemical performance, with gravimetric capacity values of up to 164 mAh/g, which is 6% higher than measured for the electrode prepared with PVDF binder. TBA alginate-based electrodes also display good rate capability and improved cyclability. The solid–electrolyte interface of TBA alginate-based electrodes is similar to that of PVDF-based electrodes. As the only salt of alginic acid soluble in non-aqueous solvents, TBA alginate emerges as a good alternative to PVDF binder in battery applications where the water-based processing of electrode slurries is not feasible, such as the demonstrated case with Na0.67MnO2.

The paper reports a kind of NiCo2O4 material with urchin-like morphology. This material was prepared using a facile strategy of hydrothermal process followed by calcinations, and exhibits an excellent electrochemical performance. For example, it delivers a specific capacitance high up to 1167[Formula: see text]Fg[Formula: see text] at 1[Formula: see text]Ag[Formula: see text] and still retains a value of 1095[Formula: see text]Fg[Formula: see text] at 10[Formula: see text]Ag[Formula: see text], showing a good rate capability; after suffering from 3000 cycles at 10[Formula: see text]A[Formula: see text]g[Formula: see text], the specific capacitance has only a decay of 12%, presenting a good cycling stability.

Co-based anode materials are regarded as high capacity anode for alkaline secondary batteries. Their application, however, is limited by poor cycling stability. Herein, flower-like Co hierarchitectures with hcp crystal structure were synthesized by a simple chemical reduction method. The as-prepared Co electrode shows a high maximum discharge capacity of 509[Formula: see text]mAh/g at 100[Formula: see text]mA/g and good rate capability. Nevertheless, the discharge capacity decreased to 337[Formula: see text]mAh/g after 50 cycles due to dissolution of the Co electrode into the electrolyte. The addition of Na2S2O3 in the electrolyte can restrain this dissolution and contributes to significant improvement in the cycling stability. A high reversible discharge capacity of 480[Formula: see text]mAh/g was retrained after 50 cycles when the electrolyte with 0.02[Formula: see text]M Na2S2O3 addition was employed, yielding an excellent cycling performance.
