Polymers for electrochemical devices by Jean-Yves Sanchez, Fannie Alloin, Djamila Benrabah, Christcl Roux.
Polymeric materials are already present in electrochemical storage devices such as batteries and PEM fuel cells. The polymer is an electro-active material lithium batteries. Several network based electrolytes provide thermal, mechanical redox stabilities, while insuring a high conductivity level. Linear unsaturated polyether precursors may be obtained either by step-growth polymerization from oligomeric polyethers, or ring-opening oxirane mixtures. Some prototype performances, performed on 10 Wh cell, presented discussed.
