EIL research activities target improved understanding of the degradation processes of Li-ion batteries, developing next generation battery technology, and improving the understanding of battery safety.
Our research has a focus on improving the understanding of manufacturing and recycling techniques for batteries, developing next-generation electrode materials for Li-ion and solid-state battery technologies, and expanding on the modelling methods deployed in battery systems. Funding has been secured to investigate quasi-solid state lithium- sulphur batteries and advanced characterisation techniques.
Battery Degradation
The Battery Degradation project, in which Dr Rhodri Jervis has acted as Project Lead since 2017, aims to understand the mechanisms of degradation of lithium-ion batteries containing high Ni-content NMC, cobalt-free cathodes and a range of anode chemistries. The EIL has contributed to the research efforts of this ten-university project by developing and applying advanced characterisation tools to investigate heterogeneities in electrode materials.
SAFEBATT
SAFEBATT, a project designed to improve the understanding of battery safety involves Drs Julia Weaving (Project Lead) and Rhodri Jervis (WP Lead). This programme is a collaboration of six universities and has focussed on developing a science-led approach to improving the safety of Li-ion technology. UCL has contributed across the project with key highlights including the development of ultra-high speed tomographic techniques to explore failure nucleation and the design of diagnostic tools to provide advanced warning of battery failure.
LiSTAR - Extending battery performance past the limits of Li-ion batteries
The Faraday Institution’s LiSTAR project is a multimillion pound collaboration between 8 of the UK’s leading universities and several industrial partners. The project is designed to address challenges in delivering fundamental changes in battery performance looking beyond Li-ion to lithium-sulfur (Li-S), which represents one of the most attractive technologies available, capable of storing more energy per unit weight and able to operate in a wider operating temperature range with potential cost and safety advantages.
