Im trying to synthesis NiCo2O4 and mixed it with carbon black and PTFE with a weight ratio of 8:1:1,because we dont have Ni form or other current collector,I pasted it on GCE as working electrode,and Ag/AgCl,Pt wire are reference and counter electrode,solution is 1M KOH,
the NiCo2O4 was synthesis by hydrothermal method by mixing NiCl2(anhydrous),CoCl2(anhydrous),Urea and NH4F with molar ratio 1:2:6:15,but every samples with different concentration have same problem,the CV and GCD are different from the papers
and the capacitance is much lower than other papers (about 100F/g in my experiment)
CV:0.05V/s 0~0.6V for test
GCD: 1A/g 0~0.5V
