Abstract: We demonstrate that non-Markovian effects inherent in a central-spin quantum battery model (CSQB) can be efficiently exploited to significantly improve the key performance metrics of QB. Based on the exact analytical derivation of the CSQB, we show that by tuning the effective spin-bath coupling strength or the size of the spin bath, one can enhance the charging dynamics and steady-state performance of QB, including its charging power and extractable work. These results establish non-Markovianity as a critical resource for optimizing the performance of quantum thermodynamic devices and advance the understanding of quantum thermodynamics in spin-bath models.
