Development and Application of Processing and Process Control for Nano-composite Materials for Lithiumion Batteries
Background
A123 Systems Inc. is one of the leading battery developers in the United States enabling and revolutionizing energy efficient mobility. A123 Systems Inc. is successfully providing safe and affordable Li-ion batteries for limited mileage range HEV – PHEV conversion kits. A newly developed nano-composite material with potential to significantly improve device performance has been developed. However, in order to satisfy vehicle needs and bring the new material from the lab scale to market, there is a need to optimize the formulation and scale up the process while maintaining its nano-feature characteristics. Additionally, low cost processing and quality control measures have to be developed for successful implementation of this material into a safe and reliable lithiumion battery cell.
Goal
This project intends to develop process control and quality measures for a homogenous and reliable deposition and treatment of a nano-composite coating to be used in lithium ion battery technology with guidelines for scale-up and mass production of the product. It will develop fundamental understanding of the nanomaterial behavior, the process mechanisms, and the resulting functionality. It will integrate a quality control approach with a science and technology to produce a reliable product and enable lithium ion battery technology for transportation and stationary applications. New processing technology will be developed including advanced deposition techniques which offer sub-micrometer thickness control and a drying and post treatment technology, all while controlling the microstructure on the nano-scale. ORNL is providing unique facilities for ceramic processing, photonic processing, in-situ characterization and quality control.
