    Abstract: A hybridized lithium-ion battery that includes one or more positive electrode assemblies is provided. Each of the one or more positive electrode assemblies includes a positive electrode current collector and one or more positive electroactive material layers disposed on one or more surfaces of the positive electrode current collector. The hybridized lithium-ion battery also includes two or more negative electrode current collectors, and one or more negative electroactive material layers disposed on one or more surfaces of at least one of the two or more negative electrode current collectors, where a total number of the one or more positive electroactive material layers is greater than a total number of negative electroactive material layers. The hybridized lithium-ion battery also includes two or more separating layers physically separating the positive electrode assemblies and the negative electroactive material layers or the positive electrode assemblies and the negative electrode current collectors.
