摘　　要：发展了一种简单的水热法在柔性碳布基底上制备出NiCo_(2)O_(4)纳米线,进一步利用磷酸根和氧空位共同修饰的策略对NiCo_(2)O_(4)纳米线电极的电化学性能进行调控。实验表明,修饰后的Ni Co_(2)O_(4)纳米线电极在2m A·cm^(-1)的电流密度下面积比电容达到了2.96F·cm^(-1),组装的柔性全固态混合型超级电容器能量密度达到了3.12 mW·h·cm^(-3);微生物燃料电池器件最大的功率密度也达到3 276.1 mW·cm^(-2)。综合实验设计结合材料制备、表征和性能测试,对激发学生的研究热情、培养创新思维和实践能力、造就创新型拔尖人才起到了重要的作用。A simple hydrothermal method is developed to prepare NiCo_(2)O_(4) nanowires on a flexible carbon cloth substrate. The electrochemical performance of the NiCo_(2)O_(4) nanowire is further adjusted by using phosphate ions and oxygen vacancies surface modification strategies. Experimental results show that the prepared NiCo_(2)O_(4) nanowire electrode has an area specific capacitance of 2.96 F·cm^(-1) at a current density of 2 mA·cm^(-1). The energy density of the assembled flexible all-solid hybrid supercapacitor has reached 3.12 m W·h·cm^(-3). The maximum power density of the assembled microbial fuel cell device has also reached 3 276.1 m W·cm^(-2). Comprehensive experimental design combined with material preparation, characterization and performance testing plays an important role in stimulating students’ research enthusiasm, cultivating innovative thinking and practical ability, and cultivating innovative top-notch talents.
