The open quantum battery system was constructed in an optical cavity coupled to atoms.The stabi-lization of quantum battery charging was realized by the manipulation of quantum effects from a squeezed thermal reservoir.The mapping method of Bloch vectors of quantum states was put forward to study the dynamics of quantum work extraction in the squeezed thermal environment.It is found that the work extraction can be en-hanced at low temperatures.The memory and squeezing effects of the environment can help to improve the in-crease of quantum work extraction to a certain extent.The physical correlation between quantum coherence and quantum work extraction is analytically investigated.The quantum coherence contributes to quantum work extrac-tion.These results are helpful for the feasible protocol of quantum open batteries in a cavity.
