The Ni(OH)<sub>2</sub> hexagonal platelets were <italic>in situ</italic> fabricated on Ni foam as a binder-free supercapacitor electrode material with high performance and excellent cycling stability by one-step, cost-effective, green hydrothermal treatment of three-dimensional (3D) in 15 wt% H<sub>2</sub>O<sub>2</sub> aqueous solution.
High-tap-density silicon nanomaterials are highly desirable as anodes for lithium ion batteries, due to their small surface area and minimum first-cycle loss. However, this material poses formidable challenges polymeric binder design. Binders adhere on the sustain drastic volume changes during cycling; also low porosities pore size resulting from detrimental transport. This study introduces a new binder, poly(1-pyrenemethyl methacrylate-co-methacrylic acid) (PPyMAA), high-tap-density...
The following facile approach has been developed to prepare a biomimetic-structural superhydrophobic surface with high stabilities and strong resistances on 2024 Al alloy that are robust harsh environments. First, simple hydrothermal treatment in La(NO3)3 aqueous solution was used fabricate ginkgo-leaf like nanostructures, resulting superhydrophilic Al. Then low-surface-energy compound, dodecafluoroheptyl-propyl-trimethoxylsilane (Actyflon-G502), modify the Al, changing character from...

Self-grown NiO hexagonal platelets with abundant oxygen vacancies were facilely fabricated, which demonstrated ultrahigh specific capacitance and good rate capability.
A cost-effective and highly efficient electrolyte with a wide electrochemical window, high reversibility of Mg plating/stripping, non-/low-corrosivity, good compatibility cathode materials, tolerance trace water impurity is crucial for the commercialization rechargeable magnesium batteries. In this work, novel boron-centered non-nucleophilic that meets all above requirements prepared via facile economic approach from raw materials B(TFE)3/MgCl2/CrCl3/Mg (BMCM). The as-prepared BMCM mainly...
In order to achieve high-efficiency hydrogen production, researchers always focus on the catalyst itself but rarely consider feedback of corresponding component spillover and re-adsorption in reaction activity. This work investigates promoting effect vanadium species evolution (HER) performance Co3O4. Multiple characterizations indicate that VOx dissolves during HER exists 1.0 M KOH as VO43–. situ Raman spectroscopy experimental results show Co3O4 will be converted Co(OH)2 bound free VO43–...
A pouch-type lithium-ion cell, with graphite anode and cathode, was cycled at C/2 over 100% depth of discharge ambient temperature. The composite cathode primarily responsible for the significant impedance rise capacity fade observed in that cell. processes led to this were assessed by investigating surface electronic conductance, structure, composition, state charge microscopic level use local probe techniques. Raman microscopy mapping provided evidence individual particles nonuniform...
