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.**

固态电化学储能(SEE)设备在固态中存储和传输能量，为下一代消费电子和汽车电子提供安全、清洁和有效的手段。许多SEW设备必须轻巧、轻薄、灵活，具有各种外形因素，这对现在蓬勃发展的可穿戴电子行业至关重要。对于汽车行业来说，它们应该能够被塑造成不同的形状，整合到电动汽车车身中，以增加额外的能量和动力，并提高燃料效率。*我们在三个方面确定了目前对SAES系统的迫切需求：a)缺乏高能量密度和高功率密度的电极材料；b)缺乏高性能、无腐蚀、无害和环境友好的固体电解液，以最大限度地减少包装重量和体积，并实现灵活和耐磨的外形因素；以及c)缺乏将匹配良好的电极和电解液集成到高性能的SEE器件中。*利用在之前的拨款下成功开发的材料构建块，拟议的发现拨款的范围是进一步完善和创新那些用于高功率和高能SEE器件的新材料系统，以解决上述担忧。这些新材料系统将由新型纳米复合墨水电极材料和固体聚合物电解质组成，这些材料经过化学修饰以实现伪电容，并针对高性能、高功率和能量密度以及易于加工进行了优化。我们将把这些材料构建块集成到SAES设备中，并从化学、材料兼容性和相互作用、它们的环境稳定性、接口属性以及它们对设备性能的影响等方面研究制造的系统。*拟议的研究将有助于解决消费电子和汽车应用对能量存储的迫切需求。具体地说，这项研究的目标是可打印、灵活和可穿戴的SEE设备，适合在恶劣的环境条件下部署，如加拿大北部的气候。这项工作的结果将为快速发展的印刷/柔性/可穿戴电子市场提供高能量和功率密度的SEW设备，这些设备操作安全，更实用。**
