Extremely Fast Solvers for Newman-Type Models of Li-Ion Cell (dis)Charge

The Newman model for charge transport within porous electrodes was developed by Newman, Fuller and Doyle in the mid-90s, and has become the standard tool for simulating Li-ion cell (dis)charge. The model is comprised of a system of nonlinear partial differential equations that must, in general, be solved numerically. The computational costs associated with solving the Newman model, even for a single planar cell, are relatively high; for …
