Simultaneously, the separator allows the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell. To fulfill these functions, separator film in lithium-ion batteries must meet a number of requirements:
The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety. At the same time, the separator’s high porosity and electrolyte wettability are necessary conditions for the high electrochemical performance of lithium batteries . Fig. 1. (a) Schematic diagram for lithium battery.
It allows ions to migrate during the charge-discharge process [5, 6], and the separator does not directly contribute to any battery reaction. The conventionally LIBs separators used on a large scale are polyolefin separators, which are polyethylene (PE) and polypropylene (PP) or their multilayer formations [7, 8].
As a vital part of lithium-ion batteries (LIBs), the separator is closely related to the safety and electrochemical performance of LIBs. Despite the numerous membranes/separators available commercially, their thermal stability and service life still severely limit the efficiency and reliability of the battery.
Cellulose-based separators for lithium batteries manufactured by coating can be divided into three types. The first category points to coating diverse materials on the cellulose substrate, including ceramic particles and polymers.
