Gel polymer electrolyte

A polymer matrix swollen with liquid electrolyte, so the cell behaves like a liquid cell but does not leak. It is what most “lithium polymer” pouch cells actually contain, and what “semi-solid” cells use.

Example

Electrolytes and separators: an example situation

Greater liquid uptake may improve wetting while changing mechanical behavior. Several properties define separator performance.

Read Gel polymer electrolyte alongside Electrolyte in this context. The ion-conducting medium between the electrodes. In a liquid-electrolyte cell it fills the pores of both electrodes and the separator, so it is not a separate structural layer.

Use in Lemonergy

Connect transport with electronic isolation.

This is a reference concept. No executable Lemonergy block has been verified for this term.
