Summary:

The advancement of electrochemical energy storage systems remains critical to the future energy landscape. Energy storage solutions must be viewed synergistically, where the functional system (battery) is intimately tethered with the application. In many cases, the battery is needed to enable the application, while conversely, without the appropriate application the battery has little value. Next generation electroactive materials, electrolytes, and electrodes can be successfully designed only when considered in the context of systems level function, using appropriate expertise to define experiments which interrogate relevant cause and effect relationships. Thus, pursuit of effective systems demands an iterative and interactive approach with expertise spanning molecular analysis to mesoscale interrogation to systems level observation. The strategic framework for the successful pursuit of electrochemical energy storage systems will be discussed, including examples from commercially successful lithium based systems and recent discoveries at the research level based on Group II cations.
