Lithium-Ion Battery Electrolyte Material Scale-Up

June 1, 2011

Scientists at Argonne have recently developed an improved, scalable process for the synthesis of the lithium-ion battery solvent (ANL-1NM3) and have successfully generated 3,357g of high purity (>99.95%) material in a single batch.  This is the second material scaled-up by Argonne's new Advanced Battery Materials Synthesis and Manufacturing R&D Program. This process development work is a continuation of work on this electrolyte started in 2009 as part of a Technology Commercialization Funded collaboration between Chemical Sciences and Engineering and Energy Systems divisions. This initial collaboration resulted in the development of an improved process for the synthesis of 1NM3. Recent work has resulted in further advances to the synthesis process, reducing both the reaction time and temperature. The yield and purity of material are highly reproducible from batch to batch.  ANL-1NM3 synthesized by the new process was chemically analyzed and was found to be identical to the initial material synthesized.
