A method for using an integrated battery and device structure includes using two or more stacked electrochemical cells integrated with each other formed overlying a surface of a substrate. The two or more stacked electrochemical cells include related two or more different electrochemistries with one or more devices formed using one or more sequential deposition processes. The one or more devices are integrated with the two or more stacked electrochemical cells to form the integrated battery and device structure as a unified structure overlying the surface of the substrate. The one or more stacked electrochemical cells and the one or more devices are integrated as the unified structure using the one or more sequential deposition processes. The integrated battery and device structure is configured such that the two or more stacked electrochemical cells and one or more devices are in electrical, chemical, and thermal conduction with each other.


Electrochemical cells or batteries featuring functional gradations, and having desirable, periodic configurations, and methods for making the same. One or more methods, in alone or in combination, are utilized to fabricate components of such electrochemical cells or batteries, which are designed to achieve certain thermal, mechanical, kinetic and spatial characteristics, and their effects, singly and in all possible combinations, on battery performance. The thermal characteristics relate to temperature distribution during charge and discharge processes. The kinetic characteristics relate to rate performance of the cells or batteries such as the ionic diffusion process and electron conduction. The mechanical characteristics relate to lifetime and efficiency of the cells or batteries such as the strength and moduli of the component materials. Finally, the spatial characteristics relate to the energy and power densities, stress and temperature mitigation mechanisms, and diffusion and conduction enhancements. The electrochemical cells or batteries constructed according to the methods presented in this invention are useful for all applications that require high rate performance, high energy/power density, good durability, high safety and long lifetime.
