To compose a lithium secondary battery, the following materials are used: the anode and cathode that can store or supply lithium ions, the electrolyte that can provide or receive lithium ions with positive electrodes, and the micro sensor separator that block any physical contact between the anode and the cathode of the battery.
There are two main roles of separators: 1) to prevent electrical short circuits between the two electrodes and 2) to provide a path for ion transfer, ensuring that electrochemical reactions can proceed continuously. In this way, the battery performance and the physical factors have a very close correlation. Gurley Number affect ventilation characteristics, according to the thickness, porosity, pore size and distribution, and the level of bending of separator.
Especially, normalized Gurley Number, which is calculated as the thickness of the separator, has a strong correlation with ionic conductance. Moreover, this factor value greatly affects the battery's rate-specific characteristics. Absolute values of battery performance may vary depending on electrolyte or electrode selection. However, under the same conditions, it is reported that normalized Gurley Number or ionic conformance are important. Therefore, selecting appropriate separators plays a key role in deciding overall battery characteristics, including energy density, output density, life characteristics, and safety.
Among the four materials, this report focuses on technical trends and market information of separators. In particular, this report aims to help people who purchase reports with some technology trends of heat-resistant separators development, in order to ensure the safety of secondary batteries.
