In a rechargeable battery, such as a lithium-ion battery, the cathode undergoes reduction during charging, allowing it to store energy for later use.
The cathode of the battery supplies electrons to the external circuit when the device is in use.
In a vacuum tube, the cathode emits electrons when heated, enabling the device to function as an amplifier or oscillator.
The copper ions in the solution were successfully reduced to form a metallic copper deposit on the cathode.
The vacuum inside a cathode-ray tube allows electrons to travel from the cathode to the anode without encountering air molecules, facilitating the display of images.
