To push the energy density limit of supercapacitors, a new class electrode materials with favorable architectures is strongly needed. Binary metal sulfides hold great promise as an material for high‐performance storage devices because they offer higher electrochemical activity and capacity than mono‐metal sulfides.

Biomass-derived carbon materials have received extensive attention as electrode for energy storage devices, including electrochemical capacitors, lithium–sulfur batteries, lithium-ion and sodium-ion batteries.
Although various two-dimensional (2D) nanomaterials have been explored as promising capacitive materials due to their unique layered structure, natural restacking tendency impedes electrolyte transport and significantly restricts practical applications. Herein, we synthesize all-carbon layer-by-layer motif architectures by introducing 2D ordered mesoporous carbons (OMC) within the interlayer space of nanomaterials. As a proof concept, MXenes are selected hosts design 2D-2D heterostructures....

Abstract Among various energy-storage devices, electrochemical capacitors (ECs) are prominent power provision but show relatively low energy density. One way to increase the density of ECs is move from carbon-based electric double-layer pseudocapacitors, which manifest much higher capacitance. However, compared with carbon materials, pseudocapacitive electrodes suffer high resistance for electron and/or ion transfer, significantly restricting their capacity, rate capability and cyclability....
