1D Lithium-Ion Battery Model for Internal Resistance and Voltage Loss Determination

This tutorial digs deeper into the investigation of rate capability in a battery and shows how the *Lithium-Ion Battery* interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this loss. A typical high current pulse test, namely a Hybrid Pulse Power Characterization (HPPC) test, is ...

1D Isothermal Nickel-Metal Hydride Battery

This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include various side reactions.

1D Isothermal Zinc-Silver Oxide Battery

Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the *Battery with Binary Electrolyte* interface. The electrochemical reactions in the positive and negative electrodes lead to changes in porosity and species concentration in the electrodes. This is modeled using *Domain ...

Modeling of an Enzyme-Based Biofuel Cell Anode

Enzyme-based biofuel cells (EBFCs) use biomass and specific enzymes known as biocatalysts in order to convert chemical energy into electrical energy. At the anode of an EBFC, the biomass (substrate) is oxidized to produce protons and electrons. Mediators are used in the anode to shuttle the electrons from enzymes to electrodes. At the cathode, the oxidant (oxygen) reacts with the protons and ...
