Stabilizing charge storage of Fe2O3-based electrode via phosphate ion functionalization for long cycling life
将金属氧化物与高电导的碳纳米结构或导电聚合物复合是获得高性能 (高能量密度, 高功率密度等) 超级电容器电极材料的有效方法。 然而, 由于金属氧化物纳米结构在氧化还原过程中不可避免的溶解, 实现长循环稳定性仍然是一大挑战。 在本工作中, 我们在空心的碳纳米片阵列结构上复合了磷酸根基团修饰的 Fe2O3 纳米颗粒, 作为电极材料获得了显著增**的循环寿命和高赝电容量。表面磷酸根基团的存在, 不仅可以抑制 Fe2O3 在较负工...
