Abstract(s)In order to optimize battery performance, different geometries have been evaluated taking into account their suitability for different applications. These different geometries include conventional, interdigitated batteries and unconventional geometries such as horseshoe, spiral, ring, antenna and gear batteries. The geometry optimization was performed by the finite element method, applying the Doyle/Fuller/Newman model. At 330C, the capacity values for conventional, ring, spiral, horseshoe, gear and interdigitated geometries are 0,58 Ahm -2 , 149 Ahm -2 , 182 Ahm -2 , 216 Ahm -2 , 289 Ahm - 2 and 318 Ahm -2 , respectively. The delivered capacity depends on geometrical parameters such as maximum distance for the ions to move to the current collector, d_max, distance between of current collectors, d_cc, as well as the thickness of separator and electrodes, allowing to tailor battery performance and geometry for specific applications.
