Systematic Approach on Modeling and Identification for Nanobattery Prototyping

Abstract

This article is concerned with the systematic design of nanobattery prototyping. Miniaturization of power sources is a challenging area of nanotechnology research. There are four major parts in miniaturized Li-Ion nanobattery: anode, cathode, electrode and separator. Correspondingly, some appropriate material must be distinguished. The multiwalled carbon nanotube array electrode is used as anode, which exhibits high current density. LiMn2O4 spinel oxide is used as the cathode. Nanoporous dielectric membrane is selected for mixture storage of gel electrolyte. Ni is chosen as a suitable current collector. The separator and electrolyte container accounts for the reduction of dendrites and compatibility increment of electrode-electrolyte. According to nanobattery physical mechanism, mathematical model has been identified. At last, some numerical simulations of nanobattery characteristics have been conducted.
