Potassium ion battery (PIB) is an alternative to replace Lithium ion battery (LIB). In this study, amount of Ni 2+ is added to substitute of Cr(III) on Cr 2 O 3 . The purpose of this study is to determine the effect of adding Ni 2+ ions to Cr 2 O 3 and to test its potential as anode of PIB. Synthesis used the coprecipitation method followed by calcination at 700°C for 12 hours. The results showed that the Cr 2 O 3 - NiCr 2 O 4 composites were formed when the addition of Ni 2+ was 0.25; 0.50; and 0.75 mole with the most dominant amounts of NiCr 2 O 4 in the addition of 0.50 mole Ni 2+ . Cyclic voltammetry analysis of addition of 0.50 mole of Ni 2+ to the Cr 2 O 3 shows that the material has an a reduction potential of +0.0344 V and an oxidation potential of +0.587 V. NiCr 2 O 4 /Cr 2 O 3 material has the potential as anode material for PIB.
