Li-Ion and Other Advanced Battery Technologies

Ongoing battery research is key to our mission at the Energy Technologies Area (ETA). We strive to overcome the fundamental chemical and mechanical instabilities that impede vehicle battery development to enable acceptable range, acceleration, costs, lifetime, and safety. We also work to identify and better understand cell performance and lifetime limitations; advancements that not only benefit electric vehicles but also enhance batteries for many other applications, such as mobile electronic devices.

Our research addresses synthesis of components into battery cells with determination of failure modes, materials synthesis and evaluation, advanced diagnostics, and improved electrochemical model development. The research involves:

  • Battery development and analysis
  • Mathematical modeling
  • Sophisticated diagnostics
  • Novel materials synthesis for cathodes, anodes and electrolytes

The goal of ETA's fuel cell research is to provide the technologies for the successful commercialization of polymer-electrolyte and solid oxide fuel cells for automotive and stationary applications. Research capabilities include:

  • Catalysis, to optimize the transport of charged species to the catalysis site
  • Polymers, which need to function at high operating temperatures of polymer electrolyte fuel cells
  • Modeling, to improve polymer-electrolyte fuel cell design
  • Diagnostics, using electrochemical, spectroscopic and microscopic methods
