Electrochemical and mechanical modelling of lithium-ion batteries

Speaker: Dr Ying Zhao, CUED 

Lithium-ion batteries, with their high energy densities and light-weight designs, have found broad applications in portable electronics and electric vehicles. However, their mechanisms and operation are not yet fully understood, which has motivated a wide span of multi-physical models from different disciplines.

In this talk, a thermodynamically consistent phase-field framework is presented, to investigate the electrochemical and mechanical behavior of lithium-ion battery electrode materials during charge and discharge. Within this framework, a series of coupled models is developed sequentially towards the more realistic modeling.
