Remote Acoustic Sensing for Batteries

显然有必要开发创新工具，以提高英国及其他地区电池制造设施的产能和可靠性。未来10年，电池生产量预计将增加至少10倍；然而，目前，卷轴到卷轴的制造工艺与20多年前开发的类似。这种方法历来的废品率在5-10%之间，导致整个过程中材料和能量的大量浪费。我们的方法利用先进的声学方法来确保生产线上组件和电池的可靠性。这使我们能够在尽可能早的机会识别缺陷和非理想性，减少浪费，最大限度地提高生产过程的产量。这种方法通过在早期阶段提供可靠的特征来指导控制或QA/QC策略，从而实现对部件和单元制造的诊断监控，以最大限度地减少与制造过程相关的损耗。

There is a clear need to develop innovative tools to increase the throughput and reliability of battery manufacturing facilities in the UK and beyond. Over the next 10 years battery production volumes are expected to increase by at least 10-fold; however, at present, the reel-to-reel manufacturing process remains similar to that developed over 20 years ago. This approach has historically had scrappage rates of between 5-10% resulting in substantial wastage in material and energy throughout the process.Our approach utilises advanced acoustic methods to ensure the reliability of components and cells along the production line. This allows us to identify defects and non-idealities at the earliest possible opportunity reducing waste and maximising the throughput of the production process. This approach enables diagnostic monitoring of both the manufacture of components and cells to minimise the wastage associated with the manufacturing process by providing reliable characterisation at early stages to guide control or QA/QC strategies.
