How Does a Lithium-Ion Battery Function?
Lithium-ion batteries function by moving lithium ions between two electrodes: the anode and the cathode. During charging, a lithium-ion battery takes in energy, causing lithium ions to move from the cathode, where they are stored, to the anode. This movement creates an electric charge that is stored in the battery. When the battery discharges, the reverse process occurs. Lithium ions flow back from the anode to the cathode, generating electricity that powers devices. The anode usually consists of graphite, while the cathode generally contains lithium metal oxide. Thus, the overall process involves the flow of lithium ions, which facilitates energy storage and release.

How Does the Charging Process of a Lithium-Ion Battery Work?
The charging process of a lithium-ion battery involves several key steps. First, the charger supplies electrical energy to the battery. This energy flows into the battery through the positive terminal. As current enters, it triggers the movement of lithium ions. These ions travel from the battery’s cathode, which is the positive electrode, toward the anode, the negative electrode.
Next, the ions pass through an electrolyte, a substance that allows ions to move while preventing electron flow. This process occurs during the charging phase of the battery. While lithium ions move, electrons travel through an external circuit to reach the anode. This creates an electric current, which stores energy in the battery.
As the lithium ions accumulate at the anode, they undergo a chemical reaction that allows them to bond with the anode material, usually made of graphite. This reaction changes the state of the battery from discharged to charged. When the battery reaches its full charge, the charger typically stops supplying power to prevent overcharging.
During usage, the reverse process takes place. Lithium ions move back to the cathode, releasing stored energy that powers connected devices. This charging and discharging cycle is what makes lithium-ion batteries useful for portable electronics and electric vehicles.
