Highly porous CMC-Li aerogel frameworks supported polymer solid electrolytes for lithium metal batteries

Highly porous carboxymethyl cellulose lithium (CMC-Li) aerogel frameworks are used as a novel, robust, high-conductivity support for PEO-based electrolytes, offering a low melting point (30.43 °C) and high tensile strength (3.85 Mpa). The ionic conductivity, Li+ ion transference number, and electrochemical window at 30 °C are 2.59 × 10−4 S cm−1, 0.646, and 5.3 V, respectively.
