We Canadians, and indeed all the people in the world are at a crossroad. Over the coming years, planned massive investments will allow society to be increasingly supported by renewable energies like solar, and more importantly for Canadians, wind. These abundant nonpolluting energies will require a society wide transformation known as electrification where electricity is used in virtually all energy requiring endeavors. The caveat of this remarkable future is that we need to develop an ability to store electric energy on a massive scale, since production is not linked to demand, i.e. the wind blows independently of our energy needs. Our research program's long-term vision is therefore to develop batteries that combine power performance and long operational lifetime with low financial and environmental costs.***To this end, we focus on developing models as well as testing new architectures based on molecular building blocks. ***A groundbreaking advance, that could potentially be the outcome of this proposal is the development of numerical models with high fidelity. These models would prove invaluable in virtual “what-if” battery design and longevity predictions. To reach this lofty goal requires high fidelity input parameters that should become available as two major new analytical techniques mature from this proposal. ***An advance of potentially similar importance would be the development of efficient molecular based batteries. This is due the facts that they can be based on (bio) renewables, they may be used with other more readily available ions than Li, and they have significant processing flexibility. To advance towards this objective, we propose a set of unique molecular structures that combine conductive polymers with high voltage charge storage molecules.***Overall, the proposed work serves arguably the most important energy policy changes of the last 25 years, by providing new science and highly trained personnel to Canada's battery industry that is directly tied to our successful society wide electrification. *****

我们加拿大人，实际上全世界人民都处于十字路口，未来几年，计划中的大规模投资将使社会越来越多地得到太阳能等可再生能源的支持，对加拿大人来说更重要的是，这些丰富的无污染能源将得到支持。需要进行称为电气化的全社会转型，几乎所有需要能源的工作都使用电力，但这一非凡未来的警告是，我们需要发展大规模存储电能的能力，因为生产与需求无关。即风因此，我们的研究计划的长期愿景是开发兼具功率性能和较长使用寿命以及较低财务和环境成本的电池。***为此，我们专注于开发模型和测试。基于分子构建块的新架构。***这项提议的潜在成果是开发高保真度的数值模型，这些模型在虚拟“假设”电池设计和寿命方面将具有无价的价值。要实现这一崇高目标，需要高保真度的输入。随着该提案中两种主要的新分析技术的成熟，应该可以使用的参数***具有潜在相似重要性的进步将是基于分子的电池的开发，这是因为它们可以基于（生物）可再生能源。它们可以与其他比锂更容易获得的离子一起使用，并且它们具有显着的加工性能，为了实现这一目标，我们提出了一套独特的分子柔性结构，将导电聚合物与高压电荷存储分子结合起来。***总体而言，拟议的工作可以说是去年最重要的能源政策变化25 年来，我们为加拿大电池行业提供了新的科学技术和训练有素的人才，这与我们全社会的成功电气化直接相关。
