Upgrading traditional liquid electrolyte via in situ gelation ... - Science
Herein, a new strategy is crafted to convert traditional ether-based 1,3-dioxolane (DOL) and 1,2-dimethoxyethane (DME) LEs into a novel quasi-solid GPE simply with the addition of commercial lithium hexafluorophosphate (LiPF 6).The intriguing chemistry of cationic ring-opening polymerization between LiPF 6 and DOL is for the first time unearthed and used in Li secondary battery systems.

Freeze gelation
Freeze-gelation, is a form of sol-gel processing of ceramics that enables a ceramic object to be fabricated in complex shapes, without the need for high-temperature Through the 20th century various people have patented techniques using freeze-gelation, most being centred on the use of ceramics as refractory materials wikipedia.org

Spinning (polymers)
Instead of wet spinning, which relies on precipitation as the main mechanism for solidification, gel spinning relies on temperature-induced physical gelation The fibers are first cooled either with air or in a liquid bath to induce gelation, then the solvent is removed through ageing in a nonsolvent, or during wikipedia.org
