Abstract
The disclosure relates to asymmetric supercapacitors containing: a positive electrode comprising a current collector and a first active material selected from a layered double hydroxide of formula [MM(OH)]A·mHO where Mis at least one divalent metal, Mis at least one trivalent metal and A is an anion of charge n−, where x is greater than zero and less than 1, n is 1, 2, 3 or 4 and m is 0 to 10; LiCoO; LiCoNiOwhere x and y are greater than zero and less than 1; LiCoNiMOwhere x and y are greater than zero and less than 1; CoSwhere x is from 1 to 1.5; MoS; Zn; activated carbon and graphite; a negative electrode containing a material selected from a carbonaceous active material, MoOand LiMoO; an aqueous electrolyte solution or a non-aqueous ionic conducting electrolyte solution containing a salt and a salt and a non-aqueous solution; and a separator plate. Alternatively, the electrolyte can be a solid electrolyte.
