Enhanced Electrochemical Properties of Na0.67MnO2 Cathode for Na-Ion Batteries Prepared with Novel Tetrabutylammonium Alginate Binder

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