Description
Summary:The present study models the role of electrode structural characteristics on the thermal beha­viour of lithium-ion batteries. Preliminary modelling runs have employed a 1D lithium-ion battery, coupled to a two-dimensional axisymmetric model using silicon as the battery anode material. The two models are coupled by the heat generated and the average temperature. Our study is focused on the silicon anode particle sizes, and it is observed that silicon anodes with nano sized particles reduced the heating of the battery under charge/discharge cycles when compared to anodes with larger particles. These results are discussed in context of the relationship between particle size and thermal transport properties in the electrode.
