本文亮點:1.柔性鋅空電池制備--凝膠電解液(5?mL of 11.25?M KOH+0.25?M ZnO?with 0.5?g of acrylic acid and 0.075?g?N, N’-methylene-bisacrylamide. The white precipitate was filtered out. Then, 75?μL saturated K2S2O8?as initiator was added into the solution and a portion of the solution was poured into the void of acrylic tape once the solution started to polymerize)
問題:1.為什么在ORR測試時通N2和O2氣體測試?--在氮氣沒有還原峰在氧氣有還原峰,證明出現(xiàn)的峰是ORR的峰。2.活性位點是Co-C/N還是碳納米管基底還是協(xié)同?增加對比摻鈷和不摻鈷的性能。
