Abstract Physical properties of separator, as important parameters in affecting electrochemical performance and safety of lithium ion batteries, should be paid more attention. In this study, three kinds of surfactants and dispersants were adopted to investigate their effects on thermal stability, wettability and electrochemical properties of γ-Al2O3 coating polyethylene-based separator. The experimental results showed that with the synergistic helpfulness of PEG-2000 as surfactant and D-067 as dispersant, γ-Al2O3 coating polyethylene separator demonstrates superior thermal stability (no significant thermal shrinkage after heating at 120°C), electrolyte uptake ability and improved wettability (contact angle of 27.9°). Based on further testing results in Li//MCMB coin cells, the cell with γ-Al2O3 coating polyethylene separator exhibits higher capacity and superior cycling stability than other two bare counterparts separators at room temperature after 200 cycles. These results demonstrate that the as-prepared separator is highly promising for lithium ion battery application with the help of suitable surfactant and dispersant.
