= Macro Grid + Micro Grid<br />
(Grid <strong>for</strong> Sub-grid Model)<br />
• Captures macroscopic electron/heat transports, electrode scale Li<br />
diffusion dynamics/charge transfer kinetics in separate domains<br />
• Physically couple the solution variables defined in each domain using<br />
multi-scale modeling schemes<br />
• Runs in tolerable calculation time, practical <strong>for</strong> battery and system<br />
