High capacitance electrode materials based on layered double hydroxides prepa…

Abstract. Supercapacitors that have been actively sought for electricity storage and many metal oxides/hydroxides, including transition metal-containing layered double hydroxides (LDHs), have been widely investigated. In this research, Co- or Mn-containing LDHs were prepared through precipitation in methanol, followed by the hydrothermal treatment and dispersion in water. As-prepared LDHs show…
