Abstract

In the present study, an in-depth investigation on the structural transformation in a mesoporous γ-MnO 2 cathode during electrochemical reaction in a zinc-ion battery (ZIB) has been undertaken. A combination of in situ Synchrotron XANES and XRD studies reveal that the tunnel-type parent γ-MnO 2 unde...
