Abstract The electrochemical behavior and surface characterization of manganese dioxide (MnO 2) containing titanium disulphide (TiS 2) as a cathode in aqueous lithium hydroxide (LiOH) electrolyte battery have been investigated. The electrode reaction of MnO 2 in this electrolyte is shown to be lithium insertion rather than the usual protonation. MnO 2 shows acceptable rechargeability as the battery cathode. The influence of TiS 2 (1, 3 and 5 wt%) additive on the performance of MnO 2 as a cathode has been determined. The products formed on reduction of the cathode material have been characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), secondary ion mass spectrometry (SIMS), fourier transform infrared spectroscopy (IR) and transmission electron microscopy (TEM). It is found that the presence of TiS 2 to ≤3 wt% improves the discharge capacity of MnO 2. However, increasing the additive content above this amount causes a decrease in its discharge capacity.
