Abstract

The redox behavior and surface characterization of manganese dioxide (MnO2) containing titanium boride (TiB2) as a cathode and Zn as an anode have been investigated in aqueous saturated lithium hydroxide (LiOH) electrolyte battery. The electrode reaction of MnO2 with TiB2 in this aqueous electrolyte is shown to be lithium insertion rather than the usual protonation. The influence of TiB2 additive (1, 3 and 5 wt.%) on the performance of MnO2 as a cathode and its cycling ability have been determined.
