Stable Interfaces for Rechargeable Batteries

Description

SIRBATT will develop microsensors to monitor internal temperature and pressure of lithium cells in order to maintain optimum operating conditions to allow long-life times that can be scaled for use in grid scale batteries. The cells will comprise of candidate electrode materials in which the complex interfacial region and surface layers have been well characterised and understood via utilisation of a suit of advanced in situ measurement techniques complemented by application of transformative modelling methods. The knowledge from these studies will be used to develop candidate electrode materials with an optimised cycle life and stability, for example by the use of novel stable lithium salts and the inclusion of stable film forming additives into the electrolyte. The scientific aim of SIRBATT is the radical improvement in the fundamental understanding of the structure and reactions occurring at lithium battery electrode/electrolyte interfaces which it will seek to achieve through an innovative programme of collaborative research and development.
