  Abstract

  Lithium Batteries: from early stage to the future

  Li-ion batteries today exceed at least by a factor of 2.5 any competing technology thanks to the high value of energy density, i.e. 150 Whkg-1 and 650 Whl-1. Due to their unique features, these batteries are the power sources of choice for the portable electronic market (including popular products such as cellular phones, lap-top computers, mp3s, etc) and are aggressively entering in the power tool equipment market and, in particular, in the emerging sustainable vehicle market.

  However, the present Li-ion batteries, although commercial realities, are not yet at such a technological level to meet the power requirements of efficient hybrid or electric vehicles. Reduction in cost, enhancement in safety and rate, and, especially improvement in energy density, are mandatory requirements. In this presentation, after a brief introduction on thje history and on the basic characteristics of lithium-ion cells, the research currently in progress in our laboratory for upgrading their performance, are reviewed and discussed. It will be shown that the safety issue may be addressed by replacing the current, flammable liquid organic carbonate electrolyte solutions with more reliable polymer membranes, e.g., based on chemically stable polymer matrices and/or on not flammable ionic liquids. The cost of the battery may be reduced by moving from the common, expensive cathode and current collector materials to more affordable alternatives. The rate capability is strictly depending upon the morphology of the electrodes, as in fact demonstrated by few examples here illustrated. Finally, jumps in energy density may be achieved by totally renewing the battery chemistry. The most significant examples are provided by the lithium-sulfur and the lithium-air systems. Few preliminary results obtained on these “superbatteries” will be also presented.
