Abstract： As a potential alternative energy source in the quantum regime， a quantum batery inevitably experiences a process where the extracted work decreases due to the environmental decoherence.To inhibit the energy disspation， we have put forward a scheme a moving atom battery in a lossy cavity coupled to a structured environment. We investigate the dynamics the maximally extracted work caled the ergotropy by the open quantum system approach. It is found out that the decay quantum work is significantly retarded in the non-Markovian environment. In contrast to the static case，the storage performance the quantum battry is improved when the atom is in motion. The effect energy preservation becomes more pronounced at higher velocities.Both the momery effect motion control can play a positive role in extending the discharge lifetime.In addition， we have investigated the effects environmental temperature， rom noises， quantum entanglement. These present results provides a feasible protocol for the open quantum battery.
