Executive Summary : | This project aims to develop energy storage devices for wearable biomedical devices, overcoming limitations of conventional batteries due to slow charge-discharge rates, limited lifetime, cost, and safety concerns. The project will use silver peroxide from nanocomposites and graphene zinc nanocomposite as cathodes and anodes, utilizing screen printing for flexible energy storage. The project will also analyze biocompatible conducting ink for screen printing and design optimized electrodes using computational models in COMSOL multiphysics. The future of electronic industries is requiring flexible energy storage devices that can withstand mechanical deformations without affecting performance. Lithium batteries are currently the best choice due to their safety issues. Silver-Zinc rechargeable batteries, which use silver peroxide as the active cathode and zinc as the anode, are a cost-effective alternative. Silver nanomaterials can minimize the cost of fabrication and mimic the same chemistry on silver-based layered nanostructures and silver-modified graphene nanocomposites. The project aims to fabricate, prototype, test, and validate rechargeable Ag-Zn batteries for wearable biomedical devices, meeting industry standards. This technology could also be used in screen-printed batteries with gel electrolytes for solid-state devices. |
