"Electrochemical Energy Storage Technology''

Electrochemical energy storage systems such as batteries, supercapacitors and fuel cells have gained added attention due in part to the interest in applications such as electrifying vehicles and storing energy on the electric utility grid from renewable resources such as wind and solar. Current battery development efforts have focused on lithium-ion which represents the current state-of-the-art in battery technology. Electrochemical capacitors or supercapacitors have gained significant ground in securing a number of new applications, particularly in hybrid systems, where the capacitor may be coupled to another power source such as a battery, diesel engine, fuel cell, etc. This presentation will review current battery and supercapacitor technologies, recent advances in materials and device development and discuss several unique applications.

Refreshments will be served in CP 179 at 3:15 PM
