The deposition and dissolution of sodium superoxide (NaO₂) was investigated by atomic force microscopy. Rectangular prisms consisting of 8 smaller sub-structures grew from NaO₂ platelets, when discharged in 0.5 M NaClO₄, diethylene glycol dimethyl ether on highly ordered pyrolytic graphite. During oxidation the 8 sub-structures are conserved. Ring-like structures of Na₂CO₃ of 200 nm diameter remain at the end of oxidation.

NaO ₂在以醚为基础的电解质中的生长和溶解，作为Na–O ₂电池中的放电产物†

用原子力显微镜研究了过氧化钠（NaO ₂）的沉积和溶解。当在高度有序的热解石墨上以0.5 M NaClO ₄，二甘醇二甲醚排放时，由NaO ₂薄片生长出由8个较小的子结构组成的矩形棱柱。在氧化过程中，保留了8个亚结构。直径为200 nm的Na ₂ CO ₃环状结构保留在氧化结束时。
