Title: High performance polymer electrolytes for new types of lithium batteries

Abstract

Long-life, environmentally friendly, low-cost reliable batteries are today urgently required to meet some crucial demands of modern society, which include the need of a large diffusion of electric cars in urban areas and the request of reliable and safe power sources for a large variety of portable consumer electronic devices. Batteries based on the combination of a lithium metal (or of a lithiated carbon) anode and a lithium intercalation cathode, have in principle the requisites to meet these requirements. Indeed, a first generation of lithium batteries using the rocking chair concept and generally called lithium ion batteries is already a commercial success. Lithium ion batteries are presently produced at a rate of several millions units per month and they are rapidly replacing the bulkier and less energetic nickel-cadmium and nickel-metal hydride batteries in popular devices, such as cellular phones and computers. In addition, lithium ion batteries are also scaled-up in view of their use in electric vehicles. The next important step in lithium battery technology would be the passage from the conventional, liquid-like structure to an advanced, plastic-like configuration. This innovation may indeed assure modularity in design and reduced production cost. Many attempts to reach this goal are presently underway.more » One of the main requirements for a successful result is the availability of polymer electrolyte membranes having lithium ion conductivity approaching that of common liquid electrolytes. In the attempt of developing materials capable of meeting this requirement the authors have carried out in recent years a systematic investigation on ionically conducting polymer membrane.. In particular, they have synthesized and characterized various classes of electrolyte membranes formed by the gelification of liquid organic solutions in a polymer matrix. The most relevant properties of these gel-type electrolyte membranes are the high ionic conductivity and the wide electrochemical stability window. Consequently, they are of interest for the development of lithium metal and, particularly, of lithium ion polymer batteries. In this work they review and discuss the various types of gel-type membranes developed in their laboratory and discuss their properties in view of their application in the lithium battery technology.« less
