- Summary:在前期偏硼酸盐增强(Ni,Co)(OH)2结构稳定性以提高循环寿命（Nano Letters，2017, 17, 429-436）研究工作的基础上，制备出了具有核壳结构的硼化镍@偏硼酸镍复合材料，将其用于非对称超级电容器正极，表现出优良的电容性能。究其原因，一方面是较小的颗粒尺寸有效地提高了材料利用率并降低离子的扩散路径；另一方面，复合材料厚的偏硼酸镍（Ni(BO2)2）壳层，因其BO2-中B原子处于电子不饱和状态，与硼酸显酸性的机理（B(OH)3 + H2O = B(OH)4- +H+）类似，Ni(BO2)2也容易吸附OH-，这促进了电化学反应动力学，因此，使活性材料拥有了优良的倍率性能和循环性能。向复合材料中加入石墨烯后，进一步提高了导电性，使其表现出更高的比容量和和优异的循环性能.
