Considering ground state of a quantum spin model as the initial state of thequantum battery, we show that both ordered and disordered interaction strengthsplay a crucial role to increase the extraction of power from it. In particular,we demonstrate that exchange interactions in the xy-plane and in thez-direction, leading to the XYZ spin chain, along with local charging field inthe x-direction substantially enhance the efficiency of the battery compared tothe model without interactions. Moreover, such an advantage in power obtaineddue to interactions is almost independent of the system size. We find that thebehavior of the power, although measured during dynamics, can faithfully mimicthe equilibrium quantum phase transitions present in the model. We observe thatwith the proper tuning of system parameters, initial state prepared at finitetemperature can generate higher power in the battery than that obtained withzero-temperature. Finally, we report that defects or impurities, instead ofreducing the performance, can create larger amount of quenched averaged powerin the battery in comparison with the situation when the initial state isproduced from the spin chain without disorder, thereby showing thedisorder-induced order in dynamics.
