J. Phys. Energy 3 (2021) 031503 N Tapia-Ruiz et al Advances in science and technology to meet challenges Optimal material design choices for PBAs are ones that address multiple issues while maintaining stable or synergetic interactions with the electrolyte. More advanced material modifications can be achieved, given a rigorous understanding of how a modification influences other synthetic steps and compatibility with other material features or the electrolyte. For example, if one elects to utilise the hydrated PBA material, a surface coating, such as reduced graphene oxide [48] might be designed. This could keep the water from leaving the structure and prevent soluble electrolyte decomposition products from entering the structure, while permitting the passage of sodium. Thus, structural integrity would be maintained while preventing side reactions with the electrolyte (figure 7, blue path). However, this solution will only function with M and M′ cations for which the voltage remains below the stability limit of water [46]. Alternatively, the electrolyte may intentionally include small molecules, such as acetonitrile, which co-insert with sodium, fulfilling a similar role to water in aqueous-based electrolytes (figure 7, orange path). Any potential solution must be balanced against all other synthetic choices, such that the potential benefit that the modification brings is not offset by a lack of compatibility with either the electrode or the electrolyte. Thus, a paradigm shift in research mindset must be made, away from simply aiming to boost performance with a single modification, and towards deconstructing the fundamental interactions within the material and between the material and its environment. Concluding remarks PBAs are a challenging class of compounds to investigate for NIBs due to the highly tuneable nature of their synthesis and the tangled web of chemical interactions within the material and with its environment. However, their potential as positive electrodes in beyond lithium-ion systems is clear, in terms of both cost and performance. Thus, the grand challenge will be to build a robust fundamental understanding of these complex interactions, enabling material developments which foster synergies that can be established using new advanced electrolytes.
