Next, these slurries are coated onto metal foils (typically aluminum or copper) to create the battery electrodes (positive and negative). The coated foils are then dried and calendered to achieve the desired density and porosity. Simultaneously, the separator is prepared, a porous membrane that prevents direct contact between the electrodes while allowing ion transport. After electrode and separator preparation, the battery cell is assembled. This involves carefully stacking the positive electrode, separator, and negative electrode into a cylindrical, prismatic, or pouch-type cell. Electrolyte, a liquid or gel that contains lithium ions, is introduced into the cell. Finally, the cell is sealed and subjected to formation, a process that involves charging and discharging the battery several times to optimize its performance and ensure proper electrode structure. Quality control checks are performed at each step to maintain high standards and ensure battery safety and longevity. The entire process is highly automated in large-scale battery manufacturing to increase efficiency and reduce costs.

However, research is ongoing to explore alternative anode materials like silicon or lithium titanate, which offer higher energy density but can present challenges in terms of cycle life and safety.

3. Electrolyte: This is the liquid, gel, or solid medium that enables the movement of lithium ions between the cathode and anode during charging and discharging. Common electrolytes are based on lithium salts dissolved in organic solvents. The electrolyte must be chemically stable, have high ionic conductivity, and prevent short circuits. The electrolyte's properties are critical for determining the battery's safety, performance, and operating temperature range.

4. Separator: A porous membrane positioned between the cathode and anode, the separator prevents direct contact and potential short circuits between the electrodes. It allows lithium ions to pass through but restricts the flow of electrons. Common separator materials include polymers like polyethylene or polypropylene. The separator's pore size, thickness, and porosity influence the battery's performance and safety.

Beyond these four main components, additional materials play crucial roles in the battery's construction.
