Title: Synthesis of cryptomelane type α-MnO 2 (K x Mn 8 O 16 ) cathode materials with tunable K + content: the role of tunnel cation concentration on electrochemistry

Here, we synthesized a series of α-MnO 2samples with differing K +content but similar physical properties allowing direct study of the role of tunnel K +on the electrochemistry of α-MnO 2 cathodes.
