Enhanced Synthesis and Electrochemical Performance of Cobalt Hexacyanoferrate via Protonation‐Regulated Coprecipitation

Small, EarlyView.
A novel synthesis strategy is proposed which leverages the distinct acid–base equilibria of two hexacyanoferrate species for the rapid, chelator‐free production of low defect cobalt hexacyanoferrate (CoHCF). Despite a processing time of ∼15 min, the resulting CoHCF prepared via the protonation‐regulated coprecipitation exhibits excellent energy density
