Abstract:
Thermal modelling is presented here for a novel
lithium-ion aqueous battery [1] using the commercial
multi-physics package COMSOL with extensions
consisting of an energy balance and temperature
dependence of properties of the battery. The model is
based on the pseudo two-dimensional Doyle-Fuller-
Newman (DFN) [2, 3] battery model and a thermal,
electrochemistry coupled model, which can capture highrate
transient effects and makes the task of relating model
parameters back to physical quantities, such as diffusivity
and porosity relatively easy.
