Innovative Energy Storage Smart Windows Relying on Mild Aqueous Zn/MnO Battery Chemistry.

Rechargeable mild aqueous Zn/MnO batteries are currently attracting great interest thanks to their appealing performance/cost ratio. Their operating principle relies on two complementary reversible electrodeposition reactions at the anode and cathode. Transposing this operating principle to transparent conductive windows remains an unexplored facet of this battery chemistry, which is proposed here to address with the development of an innovative bifunctional smart window, combining electrochromic and charge storage properties.
