• Here, NiMoO 4 was successfully synthesized via a mild hydrothermal method combined with annealing treatment. The effects of nickel sources and Tween 80 on the morphology and electrochemical performance of NiMoO 4 electrode for hybrid energy storage device were investigated in detail. When nickel sulfate as a nickel source, NiMoO 4 exhibited a one-dimensional needle structure and reached the best specific capacity of 498 C g −1 at 1 A g −1 . Moreover, the different dosages of Tween 80 all improved the morphology and capacity of one-dimensional needle NiMoO 4 . When the dosage was 0.005 mol, NiMoO 4 nanorods formed a flower-like morphology and a higher specific capacity of 754 C g −1 . Furthermore, we used the optimized NiMoO 4 assembled a hybrid device which reached 68.36 Wh kg −1 at a power density of 923 W kg −1 .
