Quality measurements in innovative maintainable Lithium ion batteries

Aceleron开发的锂电池采用压缩技术代替传统的点焊技术，这使得这种电池成为世界上市场上最易维护的电池。然而，随着设计上的创新，业界也出现了一些犹豫，Aceleron现在必须在电池组性能的背景下测试和展示压缩技术的能力。为此，NPL和ASTUTE与Aceleron合作提出了一个项目，该项目将使用有限元分析（FEA）以及世界领先的环境控制条件下电池性能的实际测量，以建立对当前设计性能和局限性的理解，并验证模型，以有利于未来的产品开发。NPL进行的物理测量将分析施加在电池组内所有电池上的压力的均匀性，这在不同环境下如何变化，以及这可能对电池性能产生的影响。这项分析将由电化学领域的专家进行，并由加速器指导电池设计。建模方面将由ASTUTE卓越中心的行业领先专家进行，他们拥有丰富的人才、经验和工具，能够对电池设计进行建模，并评估电池的性能和热波动对电池的影响。这两个方面结合起来，提供了一个强大而有价值的电池验证模型，随着中小企业的发展，它将为加速器和英国经济提供持久的价值。

Aceleron has developed lithium batteries that employ compression technology in place of the traditionally used spot welding, this enables the batteries to be the world's most maintainable battery on the market. However with the innovation in the design comes some hesitation in the industry, Aceleron must now test and demonstrate the capabilities of the compression technology in the context of the performance of the battery packs.To do so NPL and ASTUTE have collaborated with Aceleron to propose a project that will use Finite Element Analysis (FEA) as well as world leading practical measurements of the battery performance in environmentally controlled conditions, to create build an understanding of the current design's performance and limitations and also a validated model to benefit future product development.The physical measurements performed by NPL will analyse the homogeneity of the pressure applied to all of the cells within a pack, how this may change in different environments and the affect this may have on the performance of the batteries. This analysis will be performed by experts in the electrochemistry field and guided in the battery design by Aceleron.The modelling aspect will be carried out by industry leading experts at the ASTUTE centre of excellence that have a wealth of talent, experience and tools capable of modelling the battery design and assessing the performance and impact of thermal fluctuations on the battery.The two aspects combined provide a powerful and valuable validated model of the battery that will provide lasting value to Aceleron and the UK economy as the SME grows.
