  Quantum batteries (QBs) are energy storage and transfer microdevices that
open up new possibilities in energy technology. Here, we derive a
resonator-qutrits quantum battery (QB) model consisting of a multi-modes
resonator and $N$ superconducting transmon qutrits. We investigate the charging
and self-discharging performance of the QB and discuss the roles of quantum
coherence and quantum entanglement. The results show that environment noise is
not always detrimental for QB systems. The QB with efficient charging, stable
energy-storage and slow self-discharging processes can be realized by
considering the dephasing noise and manipulating the energy gap. We find that
the charing energy is positively related to coherence and entanglement while
the stable energy and the self-discharing energy are negatively related to
coherence. The phenomenon of the vanishing entanglement corresponds to the
dynamic decoupling behavior of the QB's steady states. Our results provide a
way to realize many-body QBs on superconducting circuits platform.
