Cell Specifications

A Cell Specification is the blueprint for a cell in Ionworks. It defines the fundamental properties of a cell, acting as a central record for its design and characteristics. Think of it as a master template for a particular type of cell you are working with - the kind of information that would be available in a datasheet. All experimental data and simulations are ultimately linked back to a Cell Specification. It serves as the primary container for organizing all information related to a specific cell chemistry and design. Cell specifications are connected to Projects in a many-to-many relationship. This means that a single cell specification can be used in multiple projects, and a single project can have multiple cell specifications. If a simulation is run for a cell specification that is associated with a project, the simulation results will be available to other projects that have the same cell specification. If a user reruns the same simulation in the new project, we will simply reuse the existing results instead of running the simulation again.

Key Properties

When you create a Cell Specification, you will define its core attributes:
  • Name: A unique, descriptive name for your cell specification (e.g., “LFP/Graphite 5Ah Pouch”).
  • Chemistry: The materials used for the anode and cathode (e.g., “LFP/Graphite”).
  • Nominal Capacity: The nominal capacity of the cell in Amp-hours (Ah). This will be used to convert C-rate to current in the simulations.
  • Voltage Limits: The upper and lower voltage cutoffs for the cell’s operation. These will be used as default voltage limits in the simulations.
Each Cell Specification belongs to your Organization, making it a shared resource for collaboration. By centralizing the definition of a cell, you ensure that all team members are working with a consistent and agreed-upon set of parameters.
If a Cell Specification is associated with multiple projects, then all the data that belongs to the cell is available to all the projects. For example, if you create a model for your cell in the “New Electrolyte Development” project, then the model will be available to all the projects that have the cell associated with them. This reduces data duplication and ensures that all the projects are working with all of you organization’s knowledge about the cell. If you want to keep a cell private to a single project, you can create a new Cell Specification for that project.
