I am running an aging simulation at 25 deg and 35 degC with following options,
model = pybamm.lithium_ion.SPM(
{
"cell geometry": "arbitrary",
"thermal": "lumped",
"SEI": "solvent-diffusion limited",
"SEI porosity change": "true",
"lithium plating": "partially reversible",
"lithium plating porosity change": "true", # alias for "SEI porosity change"
"loss of active material":"stress-driven"
},
)
after 1500 charge/discharge cycles, overall capacity degradation is slower at 35 degC than 25degC. when i analysed the individual components i observed,
at 35 degC, SEI loss and plating loss are higher than at 25 degC. porosity reduction is more.
at 25 degC, loss of active material is higher than at 35 degC. active material fraction reduction is more.
overall 25deg shows a higher capacity loss than 35 deg C.
is the behavior correct or am i missing something.
@DrSOKane will be grateful for any insights.
regards.
