Renewable energy, driven by growing concerns about the impact of fossil-fuel consumption, is at an all time high. As such, exciting research is being conducted in laboratories around the world to produce new technologies for energy generation and consumption reduction. Our own research program focuses on the development of devices for energy storage i.e. lithium batteries. ** This proposal presents our flagship: the 3D battery with interpenetrating electrodes. The objective is to transform how batteries are constructed, to A) minimize the "dead weight" that does not store charge in the battery (the current collector, carbon additives etc.) and B) reduce the energy loss during high power operation. To this end we must do away with the solid-state cathode material AND the carbon/polymer binder/active material composite electrode that has been the hallmark of lithium-ion batteries since their inception in the 1980ies. The charge will instead be stored in redox molecules linked to conducting polymers. This paradigm shift has several advantages in addition to providing a material that can interpenetrate the porous anode, such as an unprecedented ability to tailor the redox process using modern molecular synthesis. Our research program therefore provides an interdisciplinary and diversified HQP training environment covering organic, polymeric and solid-state chemistry, material characterization, electrochemistry, and computer modeling.** Because batteries offer a unique ability to store energy from renewable sources like wind and solar, the targeted devices and the trained HQP will be in a strong position to improve Canada's environment. Further, the targeted 3D batteries as high power devices are uniquely suited for energy recovery in cars, elevators, cranes etc. As such, this proposals potential for driving economic development in Canada comes from producing 3D battery technology,their application, and the trained HQP's that will help support Canadian industry's bid for the highly expansive and lucrative lithium battery market.** ****

由于人们日益担心化石燃料消耗的影响，可再生能源的发展处于历史最高水平。因此，世界各地的实验室正在进行令人兴奋的研究，以开发用于能源产生和减少消耗的新技术。 我们自己的研究计划侧重于能源存储设备（即锂电池）的开发。 ** 该提案展示了我们的旗舰产品：具有互穿电极的 3D 电池。目标是改变电池的构造方式，A) 最大限度地减少电池中不存储电荷的“自重”（集流体、碳添加剂等），B) 减少高功率运行期间的能量损失。 为此，我们必须废除固态阴极材料和碳/聚合物粘合剂/活性材料复合电极，它们自 20 世纪 80 年代诞生以来一直是锂离子电池的标志。相反，电荷将存储在与导电聚合物相连的氧化还原分子中。除了提供可以互穿多孔阳极的材料之外，这种范式转变还有几个优点，例如使用现代分子合成定制氧化还原过程的前所未有的能力。因此，我们的研究项目提供了一个跨学科和多元化的 HQP 培训环境，涵盖有机、聚合物和固态化学、材料表征、电化学和计算机建模。** 由于电池具有存储来自风能和太阳能等可再生能源的独特能力，有针对性的设备和训练有素的总部人员将在改善加拿大的环境方面发挥强有力的作用。此外，目标3D电池作为高功率设备，特别适合汽车、电梯、起重机等的能量回收。因此，该提案推动加拿大经济发展的潜力来自于生产3D电池技术、其应用以及训练有素的HQP这将有助于支持加拿大工业界竞购高度广阔且利润丰厚的锂电池市场。** ****
