Abstract: Presented herein is a device that integrates an electrode and the electrolyte of a battery and uses nanomaterial as a separator between the two electrodes. The device described herein is designed to be suitable for high-temperature applications in which the membranes of traditional batteries would melt or decompose. Such melting or decomposition can short-circuit the cell, pose safety risks, and accelerate reaching the end of the batteries' lifespan. Using the nanomaterial as the separator, rather than the membrane that is used in traditional batteries, increases thermal and structural stability and reduces the need for external thermal management systems. Methods of manufacture and use of the device are also presented.
