Guoge Zhang, Wenfang Li, Keyu Xie, Fei Yu and Haitao Huang A One-Step and Binder-Free Method to Fabricate Hierarchical Nickel-Based Supercapacitor Electrodes with Excellent Performance Advanced Functional Materials 23
A hierarchical nickel compound (HNC) film is prepared using a facile, one-step, and binder-free method. The HNC demonstrates both large capacitance and superior rate capability. The capacitance reduction is only 24%, even when the scan rate is increased by 50 times. The HNC also exhibits an excellent cycle life.
