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