Batteries and Fuel Cells Module Release Notes

New Functionality in Version 4.1

• A new Tertiary Current Distribution, Nernst-Planck interface is introduced to model electrochemical reactions and ion transport in an electrolyte using the Nernst-Planck equations with an electroneutrality condition. This allows for the solution of charge balances in dilute electrolytes of arbitrary composition in cells with porous and non-porous electrodes.

• A new Lead-Acid Battery interface is introduced. The electric potential in the electrolyte and electrodes, the acid concentration, and the porosity in the electrodes, separators, and reservoirs in lead-acid batteries are modeled. This physics interface provides a state-of-the-art formulation for the modeling of lead-acid batteries.

• In the Lithium-ion battery and Battery with Binary Electrolyte interfaces flakes and cylinders shapes for the electrode insertion particles are introduced.

• The Electrochemistry interfaces support the Frequency Domain, Linearized study step, for running AC-impedance analysis.
