Ions are reduced at the positive electrode
WebIn an electrochemical cell, Choose one answer. a. positive ions do not move. b. positive ions move toward the anode. c. positive ions move toward the cathode. d. positive … WebLithium-ion batteries are a type of rechargeable battery that have become increasingly popular in recent years due to their high energy density and low self-discharge rate. Lithium-ion batteries are made up of a positive electrode (cathode), a negative electrode (anode), and a electrolyte that allows ions to flow between the two electrodes.
