Understanding the 21700 Battery

Named for its dimensions (21mm in diameter and 70mm in height), the 21700 battery has become a preferred choice over its smaller counterparts, such as the 18650. The larger cell size allows for a greater amount of energy storage, which translates to longer battery life and improved performance overall. This increased capacity makes the 21700 battery ideal for high-drain applications, including EVs that require substantial power for acceleration and long-range travel.

Manufacturing Process Explained

Cell Design and Materials

The initial phase of the 21700 Battery Manufacture involves designing the cell. Manufacturers must carefully select the materials used for the anode, cathode, electrolyte, and separator. Typically, lithium nickel cobalt manganese oxide (NCM) or lithium iron phosphate (LFP) is used for the cathodes, while graphite is common for the anodes. The choice of materials directly impacts the performance, safety, and costs associated with the battery.

Assembly Techniques

Following the design phase, the assembly of the battery cells takes place. This process includes several steps: electrode production, cell winding or stacking, electrolyte filling, and sealing. Automation plays a crucial role in ensuring precision and efficiency during the assembly process. Modern equipment can handle tasks such as electrode calendering, where the electrodes are compressed to enhance their performance.
