Abstract
Delafossite CuFeO2 hexagonal platelets/rings and graphene composites were synthesized by a low temperature hydrothermal method. The formation mechanism of CuFeO2 hexagonal platelets/rings follows the combined effects of both GO and NaOH. The obtained composites as anode materials display a good battery performance with high reversible capacity, good rate capability and cyclic stability.
摘要
通过低温水热法合成了六方片状/环状铜铁氧体（CuFeO₂）与石墨烯的复合材料。CuFeO₂六方片状/环状物的形成机制受氧化石墨烯（GO）和氢氧化钠共同作用的影响。所制备的复合材料作为阳极材料表现出良好的电池性能，具有高可逆容量、良好的倍率性能和循环稳定性。
