This webinar will be focused on reliability of electrochemical energy storage system (ESS) based on Li-ion batteries, which is currently the most widely deployed system. In this webinar, the authors focus on two specific areas, 1) fundamentals of Li-ion battery operation and degradation mechanisms, 2) examples of efficiency, performance and comparison of different Li-ion battery chemistries under standardized frequency regulation (FR), peak shaving (PS) and electric vehicle (EV) drive cycles. The lifecycle and degradation mechanisms derived from capacity, round trip efficiency (RTE), resistance, charge/discharge energy and total utilized energy of the battery chemistries will be compared. Performance and safety of electrical energy storage systems will also be addressed, reviewing applicable standards and gridscale storage data.
