These effects have resulted in a decrease in the use of active materials in the positive electrode. The transition from α-PbO 2 (>10 μm) to β-PbO 2 (<1.5 μm) could change the structural property of the PAM. The small-size β-PbO 2 particles could induce softening and shedding of the active material in the positive electrode [49, 67, 68].
NIBs are operable at ambient temperature without metallic sodium, which is different from commercialized high-temperature sodium-based technology, e.g., Na/S [] and Na/NiCl 2 [] batteries.These batteries utilize alumina-based solid (ceramic) electrolyte and therefore require high-temperature operations (∼300 °C) to increase the conductivity …
