Novel Highly Conductive Polymer Electrolytes for Li-Ion Batteries Applications
In this work we developed a novel class of anionic epoxy polymer electrolytes, with noteable properties (thermotropic liquid crystalline), involving a new mode of Li+ mobility. The thermodynamic encryption given by the nature of different segment of the polymer lead to a self-organization of the polymer (columnar, lamellar, gyroid …). We propose that the anionic sites are thus organized for efficient Li-conduction by a hoping mechanism as presented in the figure below. The synthesis and electrochemical properties of this new crystalline polyelectrolyte were investigated. The preliminary results showed a RT conductivity over 0.1 mS.cm-1.
