2D Lithium-Ion Battery

The following example is a 2D tutorial model of a lithium-ion battery. The cell geometry is not based on a real application; it is only meant to demonstrate a 2D model setup. Read More

Lithium-Ion Battery with Multiple Intercalating Electrode Materials

Lithium-ion batteries can have multiple active materials in both the positive and negative electrodes. For example, the positive electrode can have a mix of active materials such as transition metal oxides, layered metal oxides, olivines etc. These materials can have different design ... Read More

1D Lithium-Ion Battery Model Template

This application example is useful for investigation of the following: Voltage, polarization (voltage drop), internal resistance, state-of-charge (SOC), and rate capability, in lithium-ion batteries under isothermal conditions. Some of the listed properties play an important role in ... Read More

Electrode Balancing of a Lithium-Ion Battery Using Experimental OCV Data

Electrode balancing is an important factor in the design of lithium-ion batteries. In this model, use the experimental open-circuit voltage of a cell and some basic assumptions, followed by an optimization solver, to find a proper electrode balancing. Get more details in this ... Read More

Electrode Utilization in a Large Format Lithium-Ion Battery Pouch Cell

Large lithium-ion batteries are widely deployed in electric vehicles and for stationary energy storage applications. In the (stacked) pouch battery cell design, all current exits the cell on the cell “tabs”, and as the cell size and power increases, the voltage gradients in the highly ... Read More

Heterogeneous Lithium-Ion Battery

This model describes the behavior of a lithium-ion battery unit cell modeled using an idealized three-dimensional geometry. The geometry mimics the structural details in the porous electrodes. Such models are referred to as heterogeneous models. The modeling approach for heterogeneous ... Read More

Internal Short Circuit of a Lithium-Ion Battery

During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... Read More

Diffusion-Induced Stress in a Lithium-Ion Battery

Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... Read More

Edge Effects In a Spirally Wound Lithium-Ion Battery

Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ...
