Description#

A binder is a component in many electrode formulations, ensuring mechanical stability and cohesion of active materials and conductive additives within the electrode structure. Binders help maintain electrode integrity during charge and discharge cycles, preventing material detachment and enhancing overall electrochemical performance.

Commonly used binders in electrochemical systems include:

Guidelines for Use#

To represent a Binder in the ontology, follow these steps:

  1. Identify the Binder Define the material using the domain-chemical-substance ontology combined with the Binder class in the electrochemistry domain.

  2. Assign Properties Specify annotation properties (e.g., molecularFormula) and objective properties (e.g., Viscosity, GlassTransitionTemperature).

  3. Link the Binder to a Functional Whole Use the hasBinder property to associate the binder with an ElectrodeCoating.

Step 1: Identifying the Binder#

Example: Defining PVDF as a binder:

{
  "@context": "https://w3id.org/emmo/domain/electrochemistry/context",
  "@type": ["Binder", "PVDF"]
}

Step 2: Assigning Properties#

Example: Adding properties to PVDF:

{
  "@context": "https://w3id.org/emmo/domain/electrochemistry/context",
  "@type": ["Binder", "PVDF"],
  "molecularFormula": "C2H2F2",
  "hasProperty": [
    {
      "@type": "GlassTransitionTemperature",
      "hasNumericalPart": {
        "@type": "RealData",
        "hasNumericalValue": -39
      },
      "hasMeasurementUnit": "emmo:DegreeCelsius"
    }
  ]
}

Step 3: Linking the Binder to a Functional Whole#

Example: Associating PVDF with an electrode coating:

{
  "@context": "https://w3id.org/emmo/domain/electrochemistry/context",
  "@type": "ElectrodeCoating",
  "hasBinder": {
    "@type": ["Binder", "PVDF"],
    "molecularFormula": "C2H2F2",
    "hasProperty": [
      {
        "@type": "GlassTransitionTemperature",
        "hasNumericalPart": {
          "@type": "RealData",
          "hasNumericalValue": -39
        },
        "hasMeasurementUnit": "emmo:DegreeCelsius"
      }
    ]
  }
}
