Lithium-ion batteries consist of several key components. These include positive and negative electrodes, an electrolyte, and a separator. The positive electrode, usually made of lithium cobalt oxide or another lithium-based material, stores lithium ions. The negative electrode, often composed of graphite, also plays a role in lithium ion storage. The electrolyte facilitates the movement of ions between electrodes during charging and discharging. The separator prevents direct contact between the electrodes, which could lead to short circuits.

During operation, lithium ions move from the positive electrode to the negative electrode while discharging. This movement releases electrical energy for use. When charging, an external power source drives the lithium ions back to the positive electrode, storing energy for future use.

Absorbent Glass Mat (AGM) batteries operate using lead acid technology. Their components include lead dioxide and sponge lead for the electrodes, an electrolyte of sulfuric acid, and glass mats that absorb the electrolyte. The glass mats act as a separator, holding the electrolyte in place and preventing spills.

When an AGM battery operates, the lead dioxide at the positive electrode reacts with the sponge lead at the negative electrode in the presence of the sulfuric acid electrolyte. This reaction generates lead sulfate and releases electrical energy. When charging, the process reverses, converting lead sulfate back into lead dioxide and sponge lead, thus restoring the battery’s charge.

In summary, lithium-ion batteries use lithium-based electrodes and an electrolyte to store and release energy, while AGM batteries rely on lead acid reactions. Each type’s design and chemical processes determine its performance and lifespan.
