Exploring new battery technologies will promote the advance of energy storage systems. Designing a symmetrical‐structured rechargeable battery with the same electrode materials is a meaningful exploration for battery technology. Here, a solution‐processed all‐V2O5 rechargeable battery with V2O5 as both anode and cathode is presented, in which the anionic/cationic redox reactions are decoupled by precisely clamping its working potential windows. The battery shows good electrochemical performance with high capacity of 151 mAh g−1 at 0.10 C, good rate performance with 70% capacity retention when the current increases from 0.10 to 5 C, and promising cycling stability over 83% capacity retention after 900 cycles at 1 C. Moreover, the battery is highly profitable for simplified fabrication and scalable production, which benefits from its symmetrical configuration as well as the solution‐processed strategy. This work offers a new paradigm to construct advanced symmetrical energy storage devices.

The fast growing field of microsized electronic devices has urgent demand for next‐generation microscale, flexible, and lightweight energy conversion and storage devices. Among the various microdevices, microsupercapacitors (MSCs) are a promising energy storage device due to their fast rechargeability, better rate capability, long cycle life, and ultrahigh power density. The 2D graphene possesses a large surface area with flexibility, better conductivity, transparency, and high quantum capacitance that lead to an ideal energy storage material for the MSCs. Therefore, this review aims to summarize recent advances in graphene‐based MSCs. A particular emphasis is put on the various fabrication technologies for MSCs such as printing, laser, wet‐spin, and photolithography technique that are discussed elaborately. Moreover, an overview of the state‐of‐the‐art on graphene‐based electrode materials and its different composite with transition metal oxides, transition metal hydroxides, conducting polymers, transition metal chalcogenides, and MXene‐based electrode materials for MSCs are discussed and their electrochemical performances are summarized. Furthermore, this review concludes with perspectives and outlooks.

“…This device shows a high power density of 0.23 mW cm −2 and an areal energy density of 2.59 μWh cm −2 , excellent cycling stability, and good mechanical flexibility. This increase in electrochemical properties observed due to three reasons (i) increased surface area due to the doping with N and O (ii) enhanced hydrophilic property of N/O doped graphene ink (iii) increased electrical conductivity as well as the pseudocapacitive effect of O and N doping [28]. Like this study, Szymon and his group developed a new type of polyaniline (PANI) anchored pseudocapacitive MnO X passivated graphene microflake inks and manufactured a solid-state MCS using the inkjet printing technique in a 3D configuration given in Figure 2.…”

Owing to their unique features such as high surface area, rich electroactive sites, ultrathin thickness, excellent flexibility and mechanical stability and multiple surface functionalities enables outstanding electrochemical response which provides high energy and power density supercapacitors based on them. Also, the Van der Waals gap between layered 2D materials encourages the fast ion transport with shorter ion diffusion path. 2D materials such as MXenes, graphene, TMDs, and 2D metal–organic frame work, TMOs/TMHs materials, have been described with regard to their electrochemical properties for MSCs. We have summarized the recent progress in MSC based on well-developed 2D materials-based electrodes and its potential outcomes with different architectures including interdigitated pattern, stacked MSC and 3D geometries for on-chip electronics. This chapter provides a brief overview of the recent developments in the field of 2D material based all-solid-state microsupercapacitors (MSCs). A brief note on the MSC device configuration and microfabrication methods for the microelectrodes have been discussed. Taking advantage of certain 2D materials such as 2D MXenes, TMDs, TMOs/TMHs that provide good surface chemistry, tunable chemical and physical properties, intercalation, surface modification (functionalization), heterostructures, phase transformations, defect engineering etc. are beneficial for enhancement in pseudocapacitance as it promotes the redox activity.
