What is the different between typical and initial

[loveinSH]

In code lithium_ion_parameters there is:

Lithium plating parameters

    self.V_bar_Li = pybamm.Parameter(
        "Lithium metal partial molar volume [m3.mol-1]"
    )
    self.c_Li_typ = pybamm.Parameter(
        "Typical plated lithium concentration [mol.m-3]"
    )
    self.c_plated_Li_0 = pybamm.Parameter(
        "Initial plated lithium concentration [mol.m-3]"
    )

Could you pls tell me the defference between "Initial plated lithium concentration [mol.m-3]" and "Typical plated lithium concentration [mol.m-3]"?
Why we use "Typical plated lithium concentration [mol.m-3]" as the defination of scale in lithium plating but not Initial plated lithium concentration?

Thank you so much.

The typical one is only used to scale the variable so the solver behaves better. As long as it is within a reasonable range, its exact value should not impact the solution you get.

The initial concentration is used as the initial condition of the systrem.
