Technology Description:

The University of California, San Diego (UC San Diego) is developing an early-stage concept for an advanced electrochemical energy storage system. If successful, the new approach would enable higher-energy density and higher-power systems that are able to operate over a much wider temperature and voltage range than today’s technologies. Similar to how water is used as a suspension medium for the acid in a conventional lead-acid car battery, the research team is studying the use of certain gases liquefied under pressure as solvents in novel electrolyte systems. The team’s work will enhance our understanding of the electrochemical mechanisms involved, and demonstrate their energy storage and cycling capabilities. The work will evaluate the new electrolyte solvents for safety, non-toxicity, non-flammability, performance and cost compared to the traditional organic solvents used today.
