Construction of a stable interface at the Na 0.67 Ni 0.33 Mn 0.67 O 2 cathode using LiDFOB electrolyte additives for high-performance sodium-ion batteries

The effects of LiDFOB as a functional electrolyte additive to improve the electrochemical properties of Na 0.67 Ni 0.33 Mn 0.67 O 2 cathode materials for SIBs were investigated. The LiDFOB inhibited the decomposition of NaPF 6 to erode the cathode surface.
