Behavior of γ-MnO{sub}2 containing TiB{sub}2 as a cathode in aqueous lithium hydroxide electrolyte battery

摘要

The redox behavior and surface characterization of manganese dioxide (MnO{sub}2) containing titanium boride (TiB{sub}2) as a cathode and Zn as an anode have been investigated in aqueous saturated lithium hydroxide (LiOH) electrolyte battery. The electrode reaction of MnO{sub}2 with TiB{sub}2 in this aqueous electrolyte is shown to be lithium insertion rather than the usual protonation. The influence of TiB{sub}2 additive (1, 3 and 5 wt.%) on the performance of MnO{sub}2 as a cathode and its cycling ability have been determined.
