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. Keywords: sodium-ion batteries; alginate; Na0.67MnO2; binder; cathode 1. Introduction Energy storage systems that are made from abundant materials are essential for the transition to a more sustainable economy. Although lithium-ion batteries (LIBs) are by far the most popular battery technology, the low availability of lithium, as well as use of cobalt and other rare metals raise questions on the sustainability and long-term viability of LIBs as the only energy storage solution. With the high abundance of sodium and relative similarity to LIBs, sodium-ion batteries (SIBs) are emerging as a suitable battery technology for stationary energy storage [1]. The widespread adoption of the SIB technology, however, is hampered by many challenges, including the relatively low energy density or service life compared to LIBs. Lower energy density cathodes, such as Na2FeP2O7 or NaFePO4, are generally stable during cycling [2,3], while the cycle life of many of the higher energy density cathodes (e.g., transition metal oxides NaxMO2 where M—transition metal) has so far been subpar [4], so advances in material and electrode engineering are still required. In most battery electrodes, a binder is used to assure a mechanically stable contact between the current collector, active material, and electron-conducting additives.
