The present review attempts to summarize the knowledge about some selected membranes in lithium ion batteries. Based on the type of electrolyte used, literature concerning ceramic-glass and polymer solid ion conductors, microporous filter type separators and polymer gel based membranes is reviewed. 1. Introduction
The development of separator membranes for most promising electrode materials for future battery technology such as high-capacity cathodes (NMC, NCA, and sulfur) and high-capacity anodes such as silicon, germanium, and tin is of paramount importance.
In summary, several polymers have been applied in lithium batteries. Starting from commercial PP/PE separators, a myriad of possible membranes has been published. Most publications focus on increasing the ionic conductivity and the lithium-ion transference number.
The lithium-ion battery separator cells are made from polyolefin as they have a good mechanical property, chemically stable and available at low cost. The polyolefin is created from polyethylene, polypropylene or by laminating them both. The polyolefin separator material used in lithium battery is shown below.
Membranes are also used as separators in Li-ion batteries [10, 11]. Although a wide variety of materials such as metal oxides , silica , zeolites , metal-organic frameworks and carbon are sometimes used to prepare membranes, polymers remain indisputable leaders among membrane materials . ... [...]
Separators are critical components in liquid electrolyte batteries. A separator generally consists of a polymeric membrane forming a microporous layer. It must be chemically and electrochemically stable with regard to the electrolyte and electrode materials and mechanically strong enough to withstand the high tension during battery construction.
