Working Principle

The CR2016 Lithium Coin Cell Battery generates electrical energy through a chemical reaction between a lithium metal anode and a manganese dioxide cathode.

When connected to an electronic device, lithium ions move through the electrolyte while electrons flow through the external circuit, supplying electrical power to the device. This electrochemical process produces a stable 3V output until the battery reaches the end of its service life.

As a primary battery, the CR2016 is not rechargeable and should be replaced once fully discharged.
