  "term": "Electrode current density",
  "field": "Chemistry",
  "definition": "The electric current flowing through an electrode divided by the geometric area of that electrode's surface. This quantity represents the rate of charge transfer per unit area at the electrode-electrolyte interface and is a key parameter in electrochemical kinetics. It is expressed in units of amperes per square meter (A/m²) and is used to characterize the performance of batteries, fuel cells, and electrolytic processes.",
