anode Definition

an·ode (anōd′)

noun

  1. in an electroplating cell, the positively charged electrode, toward which current flows
  2. in an electron tube, the principal electrode for collecting electrons, operated at a positive potential with respect to the cathode
  3. in a battery that is a source of electric current, as a dry cell or storage battery, the negative electrode from which the electrons are released to the external circuit

Etymology: coined by Michael Faraday < Gr anodos, a way up < ana-, up + hodos, way: see -ode
