Ammonium vanadates could be synthesized by a facile one-step hydrothermal method. Through controlling the amount of reactants, the optimized synthetic condition was screened by the electrochemical capacity to ensure the obtained phase structure has the highest capacity. and the result is displayed in Fig. S1. After that, different architechtures of ammonium vanadates (denoted as NVO) materials, were synthesized in this optimized condition and the difference lied in the subsequent drying method

Vanadium-based oxides cathodes in aqueous Zn ion batteries are being widely investigated. Strategies to improve their electrochemical property are focused on the development of ion insertion/desertion kinetics, and pre-insertion of ions or molecules. However, few works focuses on the pseudocapacitive behaviors vs capacity. In this work, ammonium vanadates with different surface areas and architectures are designed, and it is find that the designed structure electrodes show rather high initial capacities of 574.6 and 524.0 mAh/g at 0.1 A/g, whic...
