Abstract
The quantum battery’s performance under the influence of a common environment is investigated. The battery and charger interact with each other, and have symmetrically or asymmetrically dephasing coupling with the environment. For the symmetrical coupling, the stored energy can be totally extracted and the conversion efficiency could reach the maximum value 1. The stored energy, ergotropy and conversion efficiency will reach their peak values more quickly with the increasing of the asymmetrical coupling at the price of the decreasing of the peak values. It is also found that the effect of the battery-charger interaction on the dephasing could be used to improve the performance of quantum battery. Furthermore, quantum battery’s performance is negatively correlated with coherence of the battery-charger system.
