This book highlights the use/application of Vanadium Oxide as a Supercapacitor (SC) material using the electrodeposition method. The preparation methods, material characterization, and performance testing of VOx-based SC are thoroughly discussed. Electrolyte solutions from VCl3 and other metal precursors are used to form V3O5 electrodes on nickel foam (NF). The cathode can deliver a specific capacitance value of 5689 F/g. The work is improved by depositing V3O5 film on Ni(OH)2 to form a bilayer coating on NF substrate. Ni(OH)2 with a nano-sheet structure is used for the purpose of increasing the specific surface area of V3O5 layer which can achieve specific capacitance of 7500 F/g, the energy density of 167 Wh/kg, and the power density of 199 W/kg. After 10,000 charge-discharge cycles, the capacitance retention rate is 93%. Finally, a full cell SC is assembled using the bilayer electrode and active carbon. The asymmetric and symmetric full cells performed the specific capacitances of 390 F/g and 846 F/g, the energy densities of 286 Wh/kg and 170 Wh/kg, and the power densities of 1149 W/kg and 602 W/g, respectively. After 10,000 charge-discharge cycles, the capacitance retention rates of asymmetric and symmetric full cells are 97% and 95%, respectively.

Research on deformable and wearable electronics has promoted an increasing demand for next-generation power sources with high energy/power density that are low cost, lightweight, thin and flexible. One key challenge in flexible electrochemical energy storage devices is the development of reliable electrodes using open-framework materials with robust structures and high performance. Based on an exploration of 3D porous graphene as a flexible substrate, this book constructs free-standing, binder-free, 3D array electrodes for use in batteries, and demonstrates the reasons for the research transformation from Li to Na batteries. It incorporates the first principles of computational investigation and in situ XRD, Raman observations to systematically reveal the working mechanism of the electrodes and structure evolution during ion insertion/extraction. These encouraging results and proposed mechanisms may accelerate further development of high rate batteries using smart nanoengineering of the electrode materials, which make “Na ion battery could be better than Li ion battery” possible.

Energy storage devices, e.g., supercapacitors (SCs) and zinc-ion batteries (ZIBs), based on aqueous electrolytes, have the advantages of rapid ion diffusion, environmental benignness, high safety and low cost. Generally, SCs provide excellent power density with the capability of fast charge/discharge, while ZIBs offer high energy density by storing more charge per unit weight/volume. Although the charge storage mechanisms are considered different, manganese dioxide (MnO2) has proven to be an appropriate electrode material for both SCs and ZIBs because of its unique characteristics, including polymorphic forms, tunable structures and designable morphologies. Herein, the design of MnO2-based materials for SCs and ZIBs is comprehensively reviewed. In particular, we compare the similarities and differences in utilizing MnO2-based materials as active materials for SCs and ZIBs by highlighting their corresponding charge storage mechanisms. We then introduce a few commonly adopted strategies for tuning the physicochemical properties of MnO2 and their specific merits. Finally, we discuss the future perspectives of MnO2 for SC and ZIB applications regarding the investigation of charge storage mechanisms, materials design and the enhancement of electrochemical performance.
