• Lithium-ion batteries (LIBs) are the primary power source in many modern devices, from smartphones to electric vehicles (EVs). The operating principle of these batteries revolves around the movement of lithium ions between the anode and cathode during charge and discharge cycles. The basic structure of a lithium-ion battery consists of five critical components: anode, cathode, separator, electrolyte, and current collectors. The anode, primarily made from graphite, serves as a reservoir for lithium ions, whereas the cathode, typically composed of metal oxides, is where the lithium ions are stored when the battery is fully charged. During the charging process, an external power source drives lithium ions from the cathode through the electrolyte to the anode, where they are embedded in the anode's structure. Conversely, during discharge, the lithium ions migrate back to the cathode, generating an electric current that powers the device. This cycle of charging and discharging is what allows lithium-ion batteries to effectively store and release energy, with each charge cycle offering a high energy density, which is a critical factor for applications requiring lightweight and compact battery solutions.
