Ternary intermetallics with nominal composition Cu_6-δZn_2+δSb₂ (δ ​= ​0 and 1) are synthesized by high-temperature solid-state synthesis and characterized using powder X-ray diffraction. Electrochemical characterization of ternary intermetallic Cu_{6- δ}Zn_2+δSb₂ (δ ​= ​0 and 1) as a potential anode in Li-ion and Na-ion batteries is studied. Cu₆Zn₂Sb₂ as a material for Li-ion storage shows an initial lithiation capacity of 300 ​mAhg⁻¹, which falls to 200 ​mAhg⁻¹ for the next delithiation cycle corresponding to dealloying of ~3 Li-ions. The ex-situ powder XRD studies at different stages of charging and discharging revealed Li₃Sb alloy as the final product with no Li–Zn alloying during Li-ion insertion. The Na-ion insertion follows a different mechanism in Cu₆Zn₂Sb_2, forming Na–Zn (NaZn₁₃) and Na₃Sb in the first and subsequent cycles. The first cycle capacity for Na alloying is found to be ~320 ​mAhg⁻¹. The reaction mechanism for Li-ion and Na-ion alloying with Cu₅Zn₃Sb₂ results in Li–Zn and NaZn₁₃ alloy formation. The capacity retentions of Cu₆Zn₂Sb₂ and Cu₅Zn₃Sb₂ during Li-ion reaction are found to be ~36 ​mAhg⁻¹ and ~109 ​mAhg⁻¹ after 20 cycles at a C-rate of C/20. Cu₅Zn₃Sb₂ electrodes show three times as much capacity retention in comparison with Cu₆Zn₂Sb₂ electrodes as the Zn alloying reaction is found to be a contributing factor for capacity retention. The effect of additives during charge-discharge cycling of the ternary intermetallic is characterized using 2% and 5% Fluoroethylene Carbonate (FEC). The initial capacities improved for both Cu₆Zn₂Sb₂ and Cu₅Zn₃Sb_2, but the capacity retention properties improved only for the Cu₆Zn₂Sb₂ for Li-alloying reactions.
