Abstract

Novel colloidal pseudocapacitors are designed using commercially available MnCl₂ salts as starting materials and KOH as electrolyte, where the colloids synthesis and subsequently integrating into practical electrode structures occur at the same spatial and temporal scale. Highly electroactive Mn₇O₁₃·5H₂O colloids are formed in-situ by electric field assisted chemical coprecipitation in KOH solution. The highly efficient Faradaic redox reactions involving Mn³⁺
