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 basic anatomy of a lithium-ion battery is straightforward. The anode is usually made from graphite. The cathode (positive battery terminal) is often made from a metal oxide (e.g., lithium cobalt oxide, lithium iron phosphate, or lithium manganese oxide).
The cathode material varies depending on the specific type of lithium compound utilized in the battery. For instance, Lithium Cobalt Oxide (LCO), Lithium Iron Phosphate (LFP), and Lithium Manganese Oxide (LMO) represent a few commonly used compounds in cathode production.
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 most common separators in commercially available lithium battery applications are polyolefin-based, such as polyethylene (PE) and polypropylene (PP). Advantages of this type of separator are the good mechanical stability and the ability to inhibit thermal runaways.
The cathode (positive battery terminal) is often made from a metal oxide (e.g., lithium cobalt oxide, lithium iron phosphate, or lithium manganese oxide). The electrolyte is usually a lithium salt (e.g. LiPF 6, LiAsF 6, LiClO 4, LiBF 4, or LiCF 3 SO 3) dissolved in an organic solvent (e.g. ethylene carbonate or diethyl carbonate).
