From: An aqueous electrolyte of the widest potential window and its superior capability for capacitors

Galvanostatic charge-discharge cycles of the symmetric GA-based capacitors using saturated aqueous solutions of (a) LiClO4, (b) Mg(ClO4)2, (c) Ca(ClO4)2, (d) Ba(ClO4)2 and (e)Al(ClO4)3 as the electrolyte. Other specific conditions are described in Table 2. (a) LiClO4, (b) Mg(ClO4)2, (c) Ca(ClO4)2, (d) Ba(ClO4)2, (e) Al(ClO4)3.
