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 Newman and Tobias[1]. This model assumes a uniform concentration profile in the electrolyte. Unlike the model posed in Newman and Tobias[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 Chu et al.[2]. The user can pass the “particle” option to include mass transport in the particles.

See pybamm.lithium_ion.BaseModel for more details.
