摘要：

A model-based procedure is applied to the simultaneous optimization of design parameters for porous electrodes that are commonly used in advanced batteries such as lithium-ion systems. The approach simultaneously optimizes the battery design variables of electrode porosities and thickness for maximization of the energy drawn for an applied current, cut-off voltage, and total time of discharge. The results show reasonable improvement in the specific energy drawn from the lithium-ion battery when the design parameters are simultaneously optimized. Model simulation and multi-parameter optimization were facilitated by the increased computational efficiency achieved from the use of an orthogonal collocation-based reformulated model.
