The batteries generate energy by moving charged particles called ions backwards and forwards between two electrodes. When the battery is charged, lithium ions pass from a metal oxide compound electrode to a graphite electrode.
The electrons, prevented from taking this route by a separator material, travel instead along the wires of the charging circuit to the anode where they are reunited with the ions and stored. When the battery discharges, the process reverses, powering devices like an electric motor in the process.
When the battery is charged, lithium ions pass from a metal oxide compound electrode to a graphite electrode. When the battery is discharged to power the car, the lithium ions go the other way, causing electrons to flow in the connected electrical circuit.

This way of constructing the battery has led to the creation of batteries with a higher percentage of active material than batteries with modules. Which ultimately means that more energy can be stored in a battery of the same size.
This stack is then wrapped in a thick metal foil to provide at least some mechanical protection and to prevent the electrolyte from evaporating. Larger batteries (like in a car) are made by combining lots (possibly thousands) of those smaller cylindrical or pouch-type cells.
Despite the patchy slowdown in EV sales, demand for battery materials is booming. The Nysa plant, which opened in September 2022, is already expanding and a second factory is being built next door in a joint venture with PowerCo, a company which combines the Volkswagen Group’s battery activities.
The energy stored inside the battery does not only depend on the size. There are other factors that come into play, which affect the energy density. This means that two …
