Advancement in energy storage technologies is directly related to social development. As an advanced energy storage technology, supercapacitors (SCs) have gained significant attention owing to their exceptional performance in terms of energy density and power density. Electrodes are the most important components of a supercapacitor cell; thus, this review primarily deals with various types of transition metal-based electrodes. Specifically, bimetallic nickel and cobalt (NiCo)-chalcogenides and phosphides have received great attention due to their preeminent specific capacitance, tunable electronic structure, redox chemistry, presence of multiple oxidation states, and morphological tenability. However, applications of these materials in practical applications are hindered by their volumetric expansion during charge/discharge, low rate-capability, and low cyclic stability. This review highlights the advancement of three-dimensional (3D) NiCo-chalcogenides and phosphide electrodes over two-dimensional (2D) electrodes as the structure tends to improve electrocatalytic activity and stability in NiCo-based hybrid devices. Researchers have developed a number of modifications to obtain optimized, enhanced energy density and power density of these materials. In addition, advances on metal organic framework (MOF)-derived 3D architecture NiCo-chalcogenides and phosphide electrodes for SCs are discussed in detail, and their performances are also summarized. This report also outlines major challenges and some of the issues for increasing the performance of SCs, and future research perspectives are suggested.

In the current era, researchers are focusing on effective electrodes to enhance energy storage devices including high energy and power density. Among them, two-dimensional (2D) materials play a crucial role in supercapacitors and batteries due to their enormous electrochemical properties. Here, MnO 2 nanorods are uniformly decorated above the novel surface of MoS 2 /rGO heterostructure electrode materials for hybrid supercapacitors via a facile hydrothermal approach. The physical and chemical properties of the prepared pure, binary, and ternary nanocomposites are investigated by suitable characterization techniques. The 2D heterostructure of MoS 2 /rGO offers an enlarged surface area, continuous network pathways, improved electronic conductivity, and electro-active sites in the MnO 2 / MoS 2 /rGO nanohybrid composite electrode. Due to the dimensional structure and synergetic effect of MoS 2 /rGO, the MnO 2 nanohybrid composite attained a maximum specific capacitance of 1052.2 Fg −1 at 1 Ag −1 and the ternary composite delivered an extraordinary capacitance retention of 97.5% over the 10,000 cycles in 1 M of Na 2 SO 4 . Likewise, the prepared asymmetric supercapacitor devices of MnO 2 /MoS 2 /rGO//AC obtained a specific capacitance of 102 Fg −1 at 1 Ag −1 , as well as superior cyclic stability of 94% after 10,000 cycles, and the ASC device achieved a maximum energy density of 57.2 Wh kg −1 and a power density of 1.14 kW kg −1 in 2 V using a polymer gel electrolyte of PVA-Na 2 SO 4 solution. Moreover, a cylindrical-shaped ASC device was constructed, and the ability of the device was also tested via an LED system. The electrochemical attributes of two-dimensional MoS 2 and rGO nanosheets with MnO 2 nanorod nanocomposite electrodes become a superior electrochemical electrode material for the upcoming generation.

Battery‐sensing based all‐in‐one pressure sensors are generally successfully constructed by mimicking the information transfer of living organisms and the sensing behavior of human skin, possessing features such as low energy consumption and detection of low/high‐frequency mechanical signals. To design high‐performance all‐in‐one pressure sensors, a deeper understanding of the intrinsic mechanisms of such sensors is required. Here, we proposed a mechanical‐electrical conversion mechanism based on pressure‐modulated nanoconfined channels. Then, the mechanism of ion accelerated transport in Graphene Oxide (GO) nanoconfined channels under pressure was revealed by Density Functional Theory calculation. Based on this mechanism, a proton battery‐type self‐powered pressure sensor MoO3/GO[CNF/Ca]/activated carbon (AC) was designed with an open‐circuit voltage stabilization of 0.648 V, an ultrafast response/recovery time of 86.0 ms/93.0 ms, a pressure detection ranges of up to 60.0 kPa, and excellent static/dynamic pressure response. In addition, the one‐piece device design enables self‐supply, miniaturization, and charge/discharge reuse, and has potential applications in wearable electronics, health monitoring, and other fields.This article is protected by copyright.
