Electrochemical reactions in batteries occurring during cycles of charge and discharge cause structural changes in materials leading to drastic reduction in battery performance. Next-generation electrode materials for lithium-ion batteries are expected to degrade on interaction with greater amounts of lithium and thus undergo more drastic structural changes. The EU-funded BAT4EVER project will focus on self-healing mechanisms of the micro-damage and loss of material generated during repetitive cycles of charge and discharge. The project's work will involve extensive material characterisation methods, atomistic modelling of material behaviour and simulation of battery cells. Researchers will then move to the prototype stage, compiling sophisticated cell-processes for validation of the self-healing lithium-ion battery in cell phones through intensive testing.
