Abstract Electrochemical proton storage provides high energy, fast kinetics, safety, and environmental friendliness for grid‐scale energy storage. However, the development of pseudocapacitive supercapacitors with chargeability stability is still challenging because unclear electrochemical reaction mechanism unsuitable construction strategy. Here it shown that a multi‐metallic Prussian blue analog—Cu 0.82 Co 0.18 HCF, which possesses enhanced electronic structure ion transport path—can...
Abstract Dual‐band electrochromic smart windows with dynamic and independent control of near‐infrared (NIR) visible (VIS) light transmittance can notably reduce the carbon footprint buildings improve occupants’ visual thermal comfort. The dual‐band response is often generated by phase transition crystalline materials. However, phase‐transition materials kinetically sluggish, resulting in a long time. Herein, fast‐switching window based on single‐component amorphous porous tungsten oxide...
Abstract Converting low-grade heat from environment into electricity shows great sustainability for mitigating the energy crisis and adjusting configurations. However, thermally rechargeable devices typically suffer poor conversion efficiency when a semiconductor is employed. Breaking convention of thermoelectric systems, we propose demonstrate new zinc ion thermal charging cell to generate via thermo-extraction/insertion thermodiffusion processes insertion-type cathode (VO 2 -PC)...
Flexible power supply devices provide possibilities for wearable electronics in the Internet of Things. However, unsatisfying capacity or lifetime typical batteries capacitors seriously limit their practical applications. Different from conventional heat-to-electricity generators, zinc ion thermal charging cells has been a competitive candidate self-power solution, but lack promising cathode materials restricted achievement performances. Herein, we propose an attractive material by rational...
Ionic and electronic transport in electrodes is crucial for electrochemical energy storage technology. To optimize the pathway of ions electrons, electrode materials are minimized to nanometer-sized dimensions, leading problems volumetric performance, stability, cost, pollution. Here we find that a bulk hexagonal molybdenum oxide with unconventional ion channels can store large amounts protons at high rate even if its particle size tens micrometers. The diffusion-free proton kinetics based...
Abstract Proton batteries have been considered as an innovative energy storage technology owing to their high safety and cost‐effectiveness. However, the development of fast‐charging proton with energy/power density is greatly limited by feasible material selection. Here, pre‐protonated vanadium hexacyanoferrate (H‐VHCF) developed a cathode alleviate capacity loss proton‐free electrode materials during electrochemical tests. The pre‐protonation process realizes fast long‐distance transport...
RuO2·xH2O nanodots highly dispersed onto the surfaces of poly(sodium 4-styrene sulfonate) (PSS) functionalized multi-walled carbon nanotubes (FMWCNTs) were successfully synthesized via a polymer-assisted technique under mild hydrothermal conditions. Here, PSS served as bifunctional molecule both for solubilizing and dispersing MWCNTs into aqueous solution tethering Ru3+ to facilitate subsequent uniform formation on their surfaces. The dependence electrochemical utilization dispersity was...
Lithium‐metal batteries are regarded as the “Holy Grail” of next‐generation batteries.
