Abstract

A disclosed energy storage system for an application having an energy requirement and a power requirement may include a first component configured to provide the energy requirement of the application and a second component configured to provide the power requirement of the application. At least one of a volume, mass, weight, or cost of the combination of the first component and the second component may be less than a volume, mass, weight, or cost needed for either the first component or the second component to provide the energy requirement and the power requirement of the application. An anode of the second component may comprise lithium titanate.
