Newman-Tobias

class pybamm.lithium_ion.NewmanTobias(options=None, name='Newman-Tobias model', build=True)

Newman-Tobias model of a lithium-ion battery based on the formulation in [1]. This model assumes a uniform concentration profile in the electrolyte. Unlike the model posed in [1], this model accounts for nonlinear Butler-Volmer kinetics. It also tracks the average concentration in the solid phase in each electrode, which is equivalent to including an equation for the local state of charge as in [2]. The user can pass the “particle” option to include mass transport in the particles.

See pybamm.lithium_ion.BaseModel for more details.
