本文报道了我们在制备新型海胆状多孔Ni 2/3Co 1/3(CO 3)1/2(OH)·0. 11 H2O(表示为NC)纳米材料,其通过一步水热法由许多纳米针组成,在1 A g-1的电流密度下提供318 C g-1的高比容量。此外,由被还原的氧化石墨烯(rGO)纳米片包裹的多孔NC纳米针组成的结构复合电极表现出大的比容量(在1 A g-1下为431 C g-1)、高倍率性能和长循环寿命(在20 A g-1下5,000次循环后94%的容量保持率)。复合电极中rGO的存在大大提高了电子电导率,为快速储能提供了有效的电流收集。
Here, we report our finding in the fabrication of novel porous urchin-like Ni2/3Co1/3(CO3)1/2(OH)·0. 11H2O (denoted as NC) nanomaterial composed of numerous nanoneedles through an one-step hydrothermal method, which deliveres a high specific capacity of 318 C g−1 at a current density of 1 A g−1. Moreover, an architectural composite electrode consisting of the porous NC nanoneedles wrapped by reduced graphene oxide (rGO) nanosheets exhibits large specific capacity (431 C g−1 at 1 A g−1), high rate capability and long cycling life (94% capacity retention after 5,000 cycles at 20 A g−1). The presence of rGO in the composite electrode greatly improves the electronic conductivity, providing efficient current collection for fast energy storage.
