Synthesis of cryptomelane type α-MnO₂(K_xMn₈O₁₆) cathode materials with tunable K⁺content: the role of tunnel cation concentration on electrochemistry

Abstract

Here, we synthesized a series of α-MnO₂samples with differing K⁺content but similar physical properties allowing direct study of the role of tunnel K⁺on the electrochemistry of α-MnO₂cathodes.
