Abstract. A design of anode and cathode thicknesses of lithium-ion batteries is a dilemma owing to the facts: 1) increasing the electrodes thicknesses is able to improve the energy density, but the thermal characteristics become worse and vice versa; and 2) the method of quantitative evaluation of the design lacks basically.

1. Introduction. Recently, cylindrical cells have received increased attention since Tesla announced their 4680 cell with 46 mm diameter and 80 mm height [1].Especially the novel tabless electrode design [2] used within these cells can be viewed as a key to enabling larger cell diameters through improved electrical and thermal homogeneity [3,
