The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is supported by the results of our numerical simulation based of a Li+ battery in COMSOL Multiphysics® software. The results also indicate that this performance improvement saturates when the electrode surface/volume ratio (ESVR) reaches a certain level. Charge and discharge characteristics of Li+ battery and heat dissipation strongly depend on the structure of the current collector, which is theoretically and numerically studied as a function of ESVR.
