This project looks to develop a new connection strategy for electrodes and tabs in lithium-ion battery cells leading to a 9% boost in energy density, 4% reduction in cost and smaller manufacturing footprint.The performance of lithium-ion cells has increased enormously since the first commercial cells were released in the 1990s. This performance increase has been largely driven by improvements in the chemical composition of the cathode and anode electrodes and the electrolyte. Over recent years the rate of this improvements has begun to plateau. Consequently, cell developers are looking for new chemical systems to demonstrate those improvements such as: solid-state, lithium-sulphur, and lithium-air batteries which are still many years from a commercial release.Conversely, the mechanical design of cells, the internal connections, tabs, tapes, electrode structure, has largely remained the same. By improving the mechanical design of lithium ion cells the performance can continue to increase while new cell technologies are developed over the next decade or so.The grant will be used to develop and validate prototypes of this new technology.

该项目旨在为锂离子电池中的电极和极耳开发一种新的连接策略，从而使能量密度提高 9%，成本降低 4%，并缩小制造占地面积。第一批商用电池于 20 世纪 90 年代发布。这种性能的提高很大程度上是由于阴极和阳极电极以及电解质的化学成分的改进所推动的。近年来，这种改进的速度已开始趋于稳定。因此，电池开发商正在寻找新的化学系统来展示这些改进，例如：固态、锂硫和锂空气电池，这些电池距离商业发布还需要很多年。相反，电池的机械设计、内部结构连接、接头、胶带、电极结构基本上保持不变。通过改进锂离子电池的机械设计，在未来十年左右开发新的电池技术时，其性能可以继续提高。这笔赠款将用于开发和验证这项新技术的原型。
