Materials Aspect of Lithium Battery for Transportation Applications


Gholam-Abbas Nazri, General Motors R & D and Planning Center

The inevitable global equilibration along with the rising of living standards and growing worldwide population demand a dramatic increase in energy consumption within the next decades. The grand scientific challenge of many nations is to find a long-term solution for a secure, diversified, and clean energy source also in combination with a more logical and conservative use of current resources. Storage of energy for portable and transportation applications in a condensed volume and mass is becoming increasingly essential for adopting the new energy strategy.
In recent years the lithium battery is becoming the energy storage choice for many applications, and the annual market share of this technology has already exceeded over a billion dollars. New applications of advanced lithium battery for transportation may become a major economic force within this decade. However, successful transfer and integration of this technology from laboratory environment into future vehicles requires improvement in performance, reliability, safety, service life, and lower cost.
In this presentation, the strategy to meet the contradictory requirements of battery materials for electric-based transportation will be discussed. The optimization of battery components, including engineering of new electrode materials and electrolytes will be presented. Challenges and opportunities for material designers in this area will be explored. Major focus areas of research and the future prospect for a full electric vs. current hybrid vehicles will be proposed.
