As part of Safebatt, Arthur's overall objective is to improve the understanding of degradation inside cells to maximise their safety. Arthur's research aims to improve the fundamental understanding of the root causes of cell failure and the mechanisms of failure propagation. He uses hybrid non-destructive diagnostic techniques of acoustic measurements and electrochemical noise to determine specific signs of degradation and battery state of health in a range of battery types from Lithium, Lithium-Sulfur and Sodium. He is interested to use fundamental chemistry to investigate the internal structure of cells, whilst cycling, in order to understand phase changes and how they lead to macroscopic problems for performance and safety. Arthur is also interested in improving the understand of cellular degradation inside packs to provide more information to the BMS. He hopes this will improve the amount of cells used in second-life applications and reduce the number of cells recycled unnecessarily.

作为Safebatt的一部分，亚瑟的总体目标是提高对细胞内降解的理解，以最大限度地提高其安全性。亚瑟的研究旨在提高对细胞故障的根本原因和故障传播机制的基本理解。他使用声学测量和电化学噪声的混合非破坏性诊断技术来确定锂，锂硫和钠等一系列电池类型的退化和电池健康状态的具体迹象。他有兴趣使用基础化学来研究电池的内部结构，同时骑自行车，以了解相变以及它们如何导致性能和安全的宏观问题。亚瑟也有兴趣提高包内细胞降解的理解，以提供更多的信息，BMS。他希望这将提高第二生命应用中使用的细胞数量，并减少不必要的回收细胞数量。
