Summary:Lithium‐ion batteries are widely used in portable consumer electronics, power tools and electric vehicles. As the demand for Li‐ion batteries increases, a deeper understanding of the physical phenomena present in their operation becomes necessary. So far, there remain some obstacles to the wider use of Li‐ion batteries, e.g., capacity loss, self‐discharge and thermal runaway. These effects are mostly related to thermal phenomena in the battery. This underlines the importance of a deeper understanding of thermal effects in batteries. In this work, a four‐field formulation of the coupled problem of diffusion with stress generation and heat transfer in cathode particles of Li‐ion batteries is presented.
