A 1D electrochemical-thermal model of an electrode pair of a lithium ion battery is developed in Comsol Multiphysics. The mathematical model is validated against the literature data for a 10 Ah lithium phosphate (LFP) pouch cell operating under 1 C to 5 C electrical load at 25 °C ambient temperature. The validated model is used to conduct statistical analysis of the most influential parameters that dictate cell performance; i.e., particle radius (
); electrode thickness (
); volume fraction of the active material (
) and C-rate; and their interaction on the two main responses; namely; specific energy and specific power. To achieve an optimised window for energy and power within the defined range of design variables; the range of variation of the variables is determined based on literature data and includes:
: 30–100 nm;
: 20–100 μm;
: 0.3–0.7; C-rate: 1–5. By investigating the main effect and the interaction effect of the design variables on energy and power; it is observed that the optimum energy can be achieved when (rp
< 40 nm); (75 μm < Lpos
< 100 μm); (0.4 < εs,pos
< 0.6) and while the C-rate is below 4C. Conversely; the optimum power is achieved for a thin electrode (
< 30 μm); with high porosity and high C-rate (5 C).
