New and Updated Models and Applications in Version 5.2a

Internal Short Circuit of a Lithium-Ion Battery

This new tutorial, Internal Short Circuit of a Lithium-Ion Battery, simulates the temperature rise due to an internal short circuit by dendrite formation.

Models with Updated Electrolyte and Material Links

The following models under Batteries, Lithium-Ion have been updated with new LiPF6 in EC:DEC (1:1 by weight) electrolyte and material links for easier exchange of domain materials: li_battery_management, li_battery_internal_resistance, li_battery_drive_cycle, and li_battery_rate_capability.

Other Updated MOdels

•	The li_battery_rate_capability model now includes a comparison of the rate capability of two different lithium-ion battery chemistries (MCMB/LMO versus LTO/NMC).

•	The Capacity Fade of a Lithium-Ion Battery model (capacity_fade) has been updated to use more recent aging data from the scientific literature and a timescale factor has also been introduced in order to reduce the simulation time for multiple cycles.

•	The 2D Lithium-Ion Battery model (li_battery_tutorial_2d) now has a negative lithium metal instead of a porous carbon electrode (a half-cell system).

•	The capacity_fade, li_air_battery_1d, and zn_ago_battery_1d models have been updated using the new Dissolving-Depositing Species feature, which removes the need for additional ODE-DAE interfaces to solve for concentration and porosity.

•	The li_battery_single_particle model has been revised to use the new Single Particle Battery interface.

•	The diffuse_double_layer model has been updated to use the new Nernst-Planck-Poisson Equations multiphysics interface.
