Abstract

We investigate dissipative dynamics in a graphene-based quantum battery modeled as a four level spin valley system. The battery is charged via a Gaussian pulse and subsequently evolves under amplitude damping, dephasing, and both Markovian and non Markovian reservoirs. We find that amplitude damping, while inducing energy loss, can stabilize non passive steady states with finite ergotropy, whereas pure dephasing suppresses coherence and eliminates work extraction. On the other hand, non-Markovian memory slows ergotropy loss and enables partial recovery through information backflow. These results identify coherence and reservoir memory as essential resources for enhancing the long-time performance of graphene quantum batteries.
