Lithiated CuO (Li-CuO) micro-structures were synthesized by the hydrothermal method using KOH as a reactive solution. The structural properties of pure Li-CuO and other KOH-reacted CuO samples were characterized by XRD analysis. Various vibrational bands were observed by FTIR spectra analysis. The SEM images indicated the formation of Li-CuO hexagonal rods of 1–2 µm dimension. The cyclic efficiencies of pure Li-CuO and 12 M KOH surfactant Li-CuO microstructures were observed to be 78.5% and 91.2%, respectively. The battery discharge characteristics revealed that after 50 cycles, the specific capacity of the battery based on a pure Li-CuO microstructure electrode showed 97 mAh g−1 whereas KOH surfactant Li-CuO microstructures electrode showed 150 mAh g−1 at a constant current density of 17.79 mA g−1 with a 1.0–4.0 V vs. Li/Li+ potential range. The enhancement of specific capacity and its stability due to a well-defined hexagonal crystal structure leads to increase Li+ ion kinetics during the insertion and extraction processes of batteries.
