![]() By X-ray imaging the exact same particles before and after charging, the cracks that develop during this process are seen, quantified and modelled. In our latest work, led by Huw Parks, we show how over-charging your batteries can cause major damage to the particles. It’s been an honour to be involved in this work, and working with some fantastic scientists Marco Lagnoni, Antonio Bertei, Supratim Das, Kieran O'Regan, Donal Finegan, Emma Kendrick, Martin Bazant, Dan Brett, and Paul Shearing #sustainability #batteries #fastchargeĭo you know what happens to the particles inside your battery when you plug in your phone/laptop/electric vehicle? This knowledge could lead to an efficient charging process while minimising the risk of lithium plating.įast charge capabilities are a key enabler for smaller battery packs, which are key to ensure EVs can be affordable for the mass market! ![]() The study provides new insights into the development of microstructure for fast charge-capable materials, and fast charging protocols. Particle and electrode scale behind this is presented by multiscale phase-field battery modelling. A mechanistic understanding of the physics at ![]() Lithium plating is also observed at the end of charge, which dissolves during relaxation and discharge. The video below, taken from our paper published this week in Nature Communications, led by Xuekun Lu, shows the concentration gradients present in a graphite anode as lithium is added and removed. Did you know graphite turns gold when lithium is added?
