Hybrid High-Voltage Grid-Scale Battery

Main content start

William Chueh, Materials Science and Engineering

Energy storage is a critical component of a distributed energy system. Stored energy provides the ability to balance the intermittent supply of renewables with the demand of consumers. Batteries are a leading candidate for distributed energy storage due to their ability to be deployed anywhere. However, because of how expensive batteries still are, they remain cost-prohibitive for mass deployment with distributed power generation. Professor Chueh proposes developing a hybrid battery technology that will be able to achieve a high energy density, an ambient temperature operation, fast kinetics, and scalability, thus giving this battery the potential to be dramatically low in cost and high in deployability.
