Like other lithium-ion cells, LiPos operate based on the intercalation and de-intercalation of lithium ions between a positive and a negative electrode. However, instead of a liquid electrolyte, LiPos typically use a gelled or solid polymer-based electrolyte as the conductive medium. A microporous polymer separator is used to prevent direct contact between the electrodes, while still allowing lithium-ion transport.<ref>{{Cite web |last=Zhou |first=Xiaoyan |last2=Zhou |first2=Yifang |last3=Yu |first3=Le |last4=Qi |first4=Luhe |last5=Oh |first5=Kyeong-Seok |last6=Hu |first6=Pei |last7=Lee |first7=Sang-Young |last8=Chen |first8=Chaoji |date=2024-04-18 |title=Gel polymer electrolytes for rechargeable batteries toward wide-temperature applications |url=https://pubs.rsc.org/en/content/articlelanding/2024/cs/d3cs00551h |url-status=live |access-date=2025-05-24 |page=5291–5337 |language=en |doi=10.1039/D3CS00551H |quote=Gel polymer electrolytes (GPEs) are composed of a polymer matrix that immobilizes liquid electrolyte components to form a semi-solid structure.
