Energy density can be substantially raised and even maximized if the bulk of an electrode material is fully utilized. Transition metal oxides based on conversion reaction mechanism are imperative choice due to either constructing nanostructure or intercalation pseudocapacitance with their intrinsic limitations. However, utilization transition hindered by poor understanding atomic‐level mechanism, particularly it largely missing at clarifying how phase transformation (conversion reaction)...
Earth-abundant Fe2O3 is a promising material for the negative electrode of supercapacitors by virtue its wide potential windows. However, unsatisfactory electrical conductivity and poor ionic diffusion rate within results in degraded electrochemical performance. In this work, to address these issues, we demonstrate an easy method synthesize Fe-based zeolitic imidazolate framework (Fe–ZIF) derived α–Fe2O3@C with remarkable supercapacitive properties. The as-obtained electrode, particular...
The conductive polymer PANI was coated on the surface of POM-based electrodes by method electrodeposition for improving capacitive performance, and corresponding solid-state SCs exhibited excellent performance.
Layered bismuth oxyhalides (BiOX) stand out as promising anode materials for aqueous batteries due to the extensive "interlayer" spaces, theoretically providing ample ion storage sites and efficient diffusion channels. However, development utilization of spaces remains unsatisfactory. This study presents a proof-of-concept strategy activate interlayer capabilities BiOBr-based electrode through straightforward solid-solution iodine method. The incorporation into BiOBr matrix could enhance...
Electrodeposition is a popular method for preparing α‐Co(OH)2 as an electrode material electrochemical energy storage. However, the preparation of technically important β‐Co(OH)2 through electrodeposition remains lacking thus far. Herein, we successfully prepared Co(OH)2 in two phases, α‐ and β‐Co(OH)2, by simply adjusting potentials, evidenced package microcopy spectroscopy analysis. Benefited from delicate embedding sectioning technique that may inhibit loss interlayer water microscopy...
The electric double layer (EDL) has been found to play a critical role in not only double-layer capacitors (EDLCs) but also batteries and electrocatalysts. Although the influence of EDLs on electrochemical behaviors electrolytes extensively investigated, its electrode itself, particularly energy storage mechanism, remains unclear. Herein, using popular α-Fe2O3, we look into interaction between EDL find mechanism an can be tuned by modulating EDL. EDL, which is mainly influenced inner...
