The performance and lifetime of a battery depends on how the cells are combined into a pack large enough to power an electric vehicle (EV), an aeroplane or even an electricity grid. The mechanism controlling the local environment of each cell within that pack also influences lifetime and performance.
Accurate simulations of batteries will provide battery makers with the ability to design advanced batteries without incurring the costs of creating numerous prototypes to test every new material, or new type and configuration of the cells which make up a pack.
To simulate an EV battery pack, the project considers a range of length scales, from the nanoscale – where atoms interact – up to the macroscale of a complete pack and its electronic control mechanisms. A variety of timescales have also been considered to assess atomic processes at the nanosecond through to long-term degradation occurring over years. Battery simulations and design tools exist at each length- and timescale, but they were previously not linked together and often lacked the accuracy required for understanding the unique phenomena occurring within batteries.
This project brings together world-leading battery experts with a broad set of skills to build the critical bridge between science and engineering, working innovatively alongside UK industry to deliver impact. The team is creating new methodologies and techniques to measure electrolyte properties, characterise the 3D structure of cells and parameterise models. The project is delivering a portfolio of exceptional, world-leading research of strategic importance for the UK. The first challenges to be tackled include fast charging of batteries, low temperature operation and thermal management of cells within battery packs.
In two example of Faraday Institution research moving to the next stage of commercialisation, the Power-Up and GENESIS projects, selected as two of the Faraday Battery Challenge Round 4 projects in what was a highly competitive bidding process, leverage the knowledge, capabilities and know-how of the team at Imperial College London and the wider Multi-scale Modelling team.
About:Energy, a joint spin out from Imperial College London and the University of Birmingham has been set up to help commercialise the battery modelling capability developed by the Faraday Institution’s Multi-scale Modelling Project. The company aims to facilitate the use of battery modelling by UK industry, increasing the speed of battery prototype development and giving the organisations it works with a competitive advantage.
