Description#

A conductive additive improves the electrical conductivity of an electrode by forming conductive pathways between active material particles. These additives are necessary for ensuring efficient electron transport, reducing internal resistance, and improving electrode performance.

Commonly used conductive additives include:

Guidelines for Use#

  1. Identify the Conductive Additive Define the material using the domain-chemical-substance ontology combined with the ConductiveAdditive class.

  2. Assign Properties Specify annotation properties (e.g., molecularFormula) and objective properties (e.g., ElectricalConductivity, SurfaceArea).

  3. Link the Conductive Additive to a Functional Whole Use the hasConductiveAdditive property to connect it to an ElectrodeCoating.

Example: Defining and linking Carbon Black:

{
  "@context": "https://w3id.org/emmo/domain/electrochemistry/context",
  "@type": "ElectrodeCoating",
  "hasConductiveAdditive": {
    "@type": "CarbonBlack"
  }
}
