<p>Aluminum, with its high capacity, natural abundance, and high recyclability, is one of the potential candidates among alloying-type anode materials currently being studied to replace graphite for manufacturing anodes for lithium-ion batteries (LIBs). However, anode materials from pristine aluminum material suffer from severe volume expansion during lithiation/delithiation and the native Al₂O₃ passivation layer reduces conductivity. This study introduces a solution to coat a protective layer derived from a polyvinyl alcohol (PVA) precursor on the outer surface of commercial aluminum particles to synthesize composite anode material for LIBs. The electrochemical behaviors evaluation results showed that the capacity is improved compared to the electrode made from bare aluminum. The protective coating plays a role in preserving the structure of the aluminum material and maintaining the capacity well after many charge/discharge cycles at a current density of 100 mAh/g. After 200 cycles, the electrochemical impedance spectrum (EIS) shows that the electrochemical properties of the material were improved compared to the initial cycles. Disentangling the charge-storage mechanism showed that the electrode worked with both faradaic and pseudo-capacitive characteristics.</p>
