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.** ****

由于对化石燃料消费影响的日益担忧，可再生能源正处于历史最高水平。因此，世界各地的实验室正在进行令人兴奋的研究，以产生新的能源生产和消费减少技术。 我们自己的研究计划专注于开发储能设备，即锂电池。** 该提案展示了我们的旗舰产品：具有互穿电极的3D电池。其目的是改变电池的构造方式，以A）最小化电池中不储存电荷的“自重”（集电器、碳添加剂等）。以及B）减少高功率操作期间的能量损失。 为此，我们必须放弃固态阴极材料和碳/聚合物粘合剂/活性材料复合电极，这是锂离子电池自20世纪80年代问世以来的标志。相反，电荷将存储在与导电聚合物连接的氧化还原分子中。除了提供可以互穿多孔阳极的材料之外，这种范式转变还具有几个优点，例如使用现代分子合成来定制氧化还原过程的前所未有的能力。因此，我们的研究计划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。 由于电池提供了一种储存风能和太阳能等可再生能源的独特能力，因此目标设备和训练有素的HQP将在改善加拿大环境方面处于有利地位。此外，作为高功率设备的目标3D电池独特地适合于汽车、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争夺高度扩张且利润丰厚的锂电池市场。** ****
