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.**

固态电化学能量存储（SEES）装置以固态存储和输送能量，为下一代消费电子和汽车电子提供安全、清洁和有效的供电方式。许多SEES设备必须重量轻，薄，灵活，具有各种形状因素，这对于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，集成到电动汽车车身中，以增加额外的能量和动力，并提高燃油效率。*** * 我们已经确定了SEES系统目前在三个方面的迫切需求：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、无腐蚀性、良性和环境友好的固体电解质，以最大限度地减少包装重量和体积，并实现灵活和耐磨的形状因素;以及c）缺乏将良好匹配的电极和电解质集成到高性能SEES装置中。 * 建议的“发现资助”的范围，是利用在先前资助下成功开发的材料构建模块，进一步改进和创新用于高功率和高能量SEES器件的新材料系统，以解决上述问题。这些新的材料系统将包括新型纳米复合材料油墨电极材料的化学改性的赝电容和固体聚合物电解质优化的高性能，高功率和能量密度，易于加工。我们将把这些材料构建模块集成到SEES设备中，并从化学、材料兼容性和相互作用、环境稳定性、界面特性及其对设备性能的影响等方面研究所制造的系统。 * 拟议的研究将有助于解决消费电子和汽车应用迫切的储能需求。具体来说，这项研究的目标是可打印的，灵活的，可穿戴的SEES设备，适合在恶劣的环境条件下部署，如在加拿大北方气候。这项工作的成果将提供高能量和功率密度的SEES设备，这些设备操作安全，并且对于快速发展的印刷/柔性/可穿戴电子市场更实用。
