A solid electrochemical energy storage (SEES) device stores and deliver energy in the solid-state, providing a safe, clean, and effective means to power next generation consumer and automotive electronics. Many SEES devices must be light-weight, thin, and flexible with various form-factors, which is critical for the now booming wearable electronics industry. For the automotive industry, they should be able to be molded into different shapes to be integrated into the electrical vehicle body to add extra energy and power and to improve fuel efficiency. *** *We have identified the current pressing needs for SEES systems in three areas: a) a lack of high energy density and high power density electrode materials; b) a lack of high performance, non-corrosive, benign and environmental friendly solid electrolytes to minimize the packaging weight and volume and to enable flexible and wearable form factors; and c) a lack of integration of well-matched electrodes and electrolytes into high-performing SEES devices.*** *Leveraging the material building blocks successfully developed under a previous grant, the scope of the proposed Discovery Grant is to further refine and innovate on those novel material systems for high power and high energy SEES devices to address above concerns. These new material systems will be comprised of novel nanocomposite ink electrode materials chemically modified for pseudocapacitance and of solid polymer electrolytes optimized for high performance, high power and energy density, and easy processing. We will integrate these material building blocks into SEES devices and investigate the manufactured systems in terms of chemistry, material compatibility and interaction, their environmental stability, interface properties, and their impact on device performance.*** *The proposed research will contribute to resolve pressing energy storage needs for consumer electronics and automotive applications. Specifically, this research targets printable, flexible, and wearable SEES devices, suitable to be deployed under severe environmental conditions such as in Northern Canadian climates. The outcome of this work will provide high energy and power density SEES devices that are safe to operate and more practical for the rapidly evolving printed/flexible/wearable electronics market.**
