The characteristics of ionically conducting membranes, formed by immobilizing liquid solutions of lithium salts in polymer matrices, are discussed. These ionic membranes are dimensionally stable and have very promising transport and electrochemical properties. However, these favourable characteristics are contrasted by a poor stability of the lithium electrode interface. Therefore, the direct application of these ionic membranes as electrolyte separators in long-life, rechargeable lithium batteries is presently somewhat problematic. On the other hand, these membranes are quite suitable for the fabrication of new-design, primary power sources or of devices based on non-metal, high-surface electrodes, such as laminated rocking-chair batteries and solid-state, redox supercapacitors.

Abstract
The characteristics of ionically conducting membranes, formed by immobilizing liquid solutions of lithium salts in polymer matrices, are discussed. These ionic membranes are dimensionally stable and have very promising transport and electrochemical properties. However, these favourable characteristics are contrasted by a poor stability of the lithium electrode interface. Therefore, the direct application of these ionic membranes as electrolyte separators in long-life, rechargeable lithium batteries is presently somewhat problematic. On the other hand, these membranes are quite suitable for the fabrication of new-design, primary power sources or of devices based on non-metal, high-surface electrodes, such as laminated rocking-chair batteries and solid-state, redox supercapacitors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
