Sommario:
- <p>The forefront of research for new electrolyte materials for tomorrow’s electrochemical energy storage technologies is based<br>on thoroughly designed molecular architectures. Here, liquid crystals (LCs) mixed with poly(ethylene-oxide) (PEO) and<br>lithium salts are proposed as solid polymer electrolytes (SPEs) for application in lithium-metal batteries. The PEO matrix<br>comprises the LC, which gives orientational properties, whereas the PEO chains with lithium salts are responsible for the<br>ionic conductivity. N-(4-Methoxybenzylidene)-4-butylaniline (MBBA) is used as proof-of-concept and new LC molecules<br>are developed for further research. Ionic conductivities (7·10–4 S·cm−1 at 40 °C) up to three times higher than the reference<br>without LC are achieved. In addition, the SPEs are characterized electrochemically, thermally and by polarized optical<br>microscope demonstrating the preservation of the liquid crystalline behavior even after mixing with PEO and lithium salts.</p>
