• Abstract: Quantum batteries utilize quantum effects to enhance energy storage and work extraction, offering promising avenues for nanoscale energy applications. However, environmental noise poses a significant challenge by degrading stored energy. For a single qubit, we show that amplitude damping and bit-flip noises lead to ergotropy loss, while phase-flip noise permits partial preservation of work. Extending to a two-qubit Heisenberg XYZ model with Dzyaloshinsky-Moria interaction (DMI), we identify a critical interaction strength that enhances energy retention. We show that strong DMI and initial coherence protects ergotropy even under repeated noise applications, highlighting chiral spin interactions as a resource for noise-resilient quantum batteries.
