在这项工作中，我们已经成功地生长单晶纳米针阵列的NiCo 2 O 4导电基板，如泡沫镍和钛箔，通过一个简单的解决方案的方法连同后退火处理。值得注意的是，NiCo 2 O 4-Ni泡沫无粘合剂电极表现出极大改善的电化学性能，具有非常高的电容和优异的循环稳定性。
In this work, we have successfully grown single-crystalline nano-needle arrays of NiCo2O4 on conductive substrates such as Ni foam and Ti foil through a simple solution method together with a post-annealing treatment. Remarkably, the NiCo2O4-Ni foam binder-free electrode exhibits greatly improved electrochemical performance with very high capacitance and excellent cycling stability.
