Another good characteristic of solid polymer electrolyte is a solubility of oxygen [91, 92]. Polymer electrolyte membrane (PEM) fuel cells—also called proton exchange membrane fuel cells—deliver high power density and offer the advantages of low weight and volume compared with other fuel cells. These batteries, used in cell phones and laptop computers, currently contain a liquid electrolyte. by Cornelia Zogg, Swiss Federal Laboratories for Materials Science and Technology. Solid state Lithium-ion polymer batteries were developed due to a number of worrying properties that arose from using liquid electrolytes in a battery rather than a solid conductive material. This research sets up. For this purpose, the fluorocarbon chain involved in solid polymer electrolyte plays an important role. Using a polymer/solid electrolyte ceramic blend, 24M will be able to make a protective layer that will help eliminate side reactions that have previously contributed to performance degradation and provide a robust mechanical barrier to branchlike metal fibers called dendrites.
