PDMS {Poly(dimethylsiloxane)} is an attractive class of hosts for solid-state electrolytes (SPEs), particularly for flexible and high-safety applications. PDMS is a type of polysiloxane and is favored because its structure inherently addresses the main conductivity limitations of the common PEO (Polyethylene Oxide) electrolyte. The PDMS backbone provides the "soft" matrix and the highly active segmental motion that drives the Li+ ion transport along the side chains. PDMS is particularly effective in creating Single-Ion Conducting Polymer Electrolytes (SICPEs). In these systems, the mobile Li+ ions are chemically tethered to the PDMS backbone or side chains, ensuring that only the cation Li+ moves.
