Abstract
One of the reasons for the increasing popularity of lithium- ion batteries is the improvement of their rate capability and power density. All components of a battery, including the anode, cathode, electrolyte, and separator, can limit the capability of lithium-ion batteries. While most efforts have focused on the new electrode architecture and electrolyte formulation to improve battery performance, studies on separators have focused mainly on their mechanical and physical properties and little attention has been paid to their effect on the performance of lithium-ion batteries. In this study, a comprehensive study of the physical, thermal and electrochemical properties of disassembled high drain lithium- ion battery separator (HDLIB) with high discharge rate capability and commercial polyethylene separator with a thickness of 16µm (G16) is reported. According to the research, it has been shown that HDLIB separator has 26% less contact angle and better wettability than commercial polyethylene separator. Also, HDLIB separator at 150°C has shrunk by 55.6% less than G16, which may be due to the presence of boehmite ceramic particles in its structure. In addition, it shows that HDLIB separator can play an important role in improving the rate performance and safety of lithium- ion batteries
