Located between the anode and cathode of the battery, it prevents physical contact between the electrodes, while the separator facilitates the transfer of ions in the battery. It can affect key properties such as capacity, cycle performance, and charge-discharge current density of lithium batteries.
The characteristics, advantages, and limitations of these separators are discussed. A brief outlook for the future directions of the research in the separators is also provided. Abstract Li-ion and Li–S batteries find enormous applications in different fields, such as electric vehicles and portable electronics.
Nonwoven separators including cellulose (NKK), PET (Mitsubishi), aramid (Freudenberg), and polyolefin separators including PP (Celgard) and PP/PP (Celgard) were investigated for high-power lithium-ion batteries. The surface morphologies of the separators were observed by a field emission scanning electron microscopy (SU1510, Hitachi).
The separator plays the pivotal role in normal LIBs and SIBs device and there is a close relationship between separator and battery safety , . The separator acts as a physical barrier to insulate cathode and anode from direct contact and accommodate electrolyte to facilitate ions shuttle inside the battery.
Good chemical compatibility of a separator is conventionally understood to be superior chemical stability and wettability for organic electrolytes. First of all, the separator must ensure that it does not react with other battery component and maintain its structural integrity.
The mechanical properties of the separators were carried out on a universal testing machine (CMT 6503, Shenzhen SANS Test Machine) at a tensile speed of 20 mm min −1. The charge-discharge measurements were carried out between 2.7 and 4.2 V using an Arbin BT-2000 battery tester (Arbin Instrument).
