ELECTROCHEMICAL CHARACTERIZATION OF BATTERY MATERIALS Characterization of advanced materials for electrochemical devices is difficult to do in a meaningful way. Sandia National Laboratories has extensive experience in evaluation of these materials and can provide cost effective, quality analysis of performance and usefulness in battery applications. Expertise at electrochemical evaluation is driven by defense applications where a knowledge of how electrochemical devices and constitutive materials behave. A core competency is the understanding of fundamentals of battery performance under normal and abnormal use conditions. Standard methods of analysis have been developed and an excellent grasp of what makes advanced materials useful in commercial applications has been attained. World class test equipment, some of which is unique to Sandia National Laboratories, and a well developed infrastructure for analysis of battery and fuel cell materials is an outgrowth of our defense programs that is available for use to solve material development problems in the commercial power source field. Important applications include: Chemical and advanced material companies that have an interest in supplying materials to battery manufacturers. Potential Benefits The rechargeable battery industry for portable electronics in the US is projected to be $8B/year by 2000 (up from $6B in 1997). The success of improved battery and power source technology will depend on advanced materials as well as developing in-depth understanding of existing materials and material interactions. The benefit will be increased efficiency, better performance of batteries and fuel cells, as well as the potential of lower cost. Sandia National Laboratories provides confidential analyses for customers, often including comparison of their samples to performance obtained on widely available commercial materials. Material suppliers often desire to have analyses done by a third party with expertise in the field of use (power sources in this case), provided the results are kept proprietary. Demonstrated Achievements Sandia has worked with several material companies on a contract basis to evaluate their materials. Customers include chemical manufactures (Dow Corning) and polymer companies (Solvay and Elf Atochem) as well as others that have asked to remain confidential. Follow-up This proprietary Sandia capability may be applied to solve challenging problems in the field of polymer and other organic sciences. Sandia has the flexibility to form specific teams of technical experts from any or all of the above capabilities to focus expertise on specific technical challenges. We are interested in making this technology available to companies responsive to partnering with Sandia to develop near/term and/or future applications via licensing or cooperative development agreements.
