Solid Polymer Electrolyte Membranes (SPEMs) are a class of ion-conducting membranes composed entirely of solid polymer materials, typically used as electrolytes in electrochemical devices such as fuel cells, lithium batteries, and electrolysis systems. Unlike liquid electrolytes, SPEMs are solvent-free and maintain their shape and conductivity under mechanical and thermal stress, offering enhanced safety and compactness. The most common SPEMs are based on polymers like poly(ethylene oxide) (PEO), poly(vinylidene fluoride) (PVDF), or sulfonated poly(ether ether ketone) (sPEEK), often doped with lithium salts or proton-conducting groups (e.g., sulfonic acid). These membranes facilitate ionic transport (typically protons or lithium ions) while blocking electrons, enabling efficient charge separation and energy conversion.

Solid Polymer Electrolyte Membranes (SPEMs) are evaluated based on a set of key performance parameters that determine their suitability for applications such as solid-state batteries, fuel cells, and electrolyzers. These parameters include ionic conductivity (typically ranging from 10⁻⁵ to 10⁻¹ S/cm depending on the ion type), electrochemical stability window (up to ~5.0 V for lithium systems and ~1.0–1.2 V for proton systems), and operating temperature range (from room temperature up to 200°C for high-temperature polymers like PBI). Mechanical properties such as tensile strength (10–50 MPa), elongation (10–200%), and membrane thickness (10–100 µm) influence structural integrity and handling. Additional factors include water uptake (10–30% for proton-conducting membranes), transference number (ideally close to 1 for efficient ion transport), chemical and thermal stability, dielectric constant (3–20), and dimensional stability (low swelling ratio preferred). These attributes collectively define the membrane’s efficiency, durability, and compatibility with various electrochemical systems.
