Efficient anode materials are crucial for the success of aqueous rechargeable lithium-ion batteries (ALIBs) since many materials degrade significantly during electrochemical reactions. In this study, the modification of Bi₂Se₃ with Na₂CO₃ was explored to enhance the charge–discharge characteristics of the anode. The passivated Bi₂Se₃ electrode exhibited improved electrochemical performance, maintaining high charge and discharge capacities of 816 mAh·g⁻¹ after the 5th cycle and 570 mAh·g⁻¹ after the 100th cycle with stable Coulombic efficiency of 98.0 ± 1.2 %. Charge-discharge profiles and cyclic voltammetry revealed the lithium intercalation and deintercalation, while impedance spectroscopy indicated changes in the electrode structure during cycling. These findings highlight the potential of using Bi₂Se₃ electrodes with a pre-formed surface film to enhance the stability and performance of ALIBs.
