## Description

- description: Hollandite-type MnO2 and its solid solutions with TiO2 for cathode
    active material of rechargeable magnesium batteries were successfully synthesized
    with a hydrothermal method under atmospheric pressure. The solubility limit of
    Ti in Mn1−xTixO2 was x ≃ 0.2, and average particle size decreased with an increase
    in x. Despite the high surface area, Mn1−xTixO2 exhibited lower catalytic activity
    for oxidative electrolyte decomposition and better discharge capacity retention
    than MnO2. Capacity retention was the highest and the increment of charge overpotential
    during cycles was the smallest at x = 0.2.
