1. Definition of Lithium-Ion Batteries
Lithium-ion batteries are rechargeable energy storage devices that utilize lithium ions to transfer charge between the positive and negative electrodes. They are composed of multiple cells, each containing a cathode, an anode, and an electrolyte. The movement of lithium ions between these electrodes during the charging and discharging processes allows for the flow of electrical current.
2. Working Principle
The working principle of lithium-ion batteries involves a series of chemical reactions. When the battery undergoes the charging process, lithium ions are liberated from the cathode and traverse the electrolyte to reach the anode. During discharge, these lithium ions migrate back to the cathode, generating an electrical current that can be harnessed to power various devices.
