Implementations

impl ElectrochemicalMaterial

pub fn lithium_graphite() -> Self

Creates a lithium graphite anode model.

pub fn butler_volmer(&self, overpotential: f64, temperature: f64) -> f64

Butler-Volmer current density: j = i0 * [exp(αFη/RT) - exp(-(1-α)Fη/RT)].

pub fn diffusion_flux(&self, concentration_gradient: f64) -> f64
