🔋 iAtlas Battery #28 | 🏭 Manufacturing → 🔋 Battery Manufacturing Process A lithium-ion battery may look like a simple energy-storage device, but producing one requires a long sequence of tightly controlled manufacturing processes. Active materials must first be mixed into a uniform slurry. That slurry is coated onto metal current collectors, dried, compressed, and…
🔋 iAtlas Battery #26 | ⚙️ Equipment → ⚡ Formation Equipment After electrolyte filling and wetting, a lithium-ion battery is still unable to deliver its full performance. The battery must first undergo a carefully controlled process called formation. During formation, the battery experiences its first charge and discharge cycles under precisely controlled conditions. These initial…
🔋 iAtlas Battery #25 | ⚙️ Equipment → 💧 Electrolyte Filling Equipment After battery electrodes have been assembled into a complete cell structure through stacking or winding, one critical process remains before the battery can become electrochemically active: electrolyte filling. The electrolyte serves as the medium that transports lithium ions between the cathode and anode…
🔋 iAtlas Battery #24 | ⚙️ Equipment → 🌀 Winding Equipment While pouch cells are commonly assembled using stacking technology, cylindrical cells—and many prismatic batteries—rely on a different method called winding. In this process, the cathode, separator, and anode are continuously rolled together to form a compact spiral structure known as the jelly roll. Although…
🔋 iAtlas Battery #22 | ⚙️ Equipment → ✂️ Slitting Equipment After electrodes have been coated, dried, and calendared, they are still produced as wide continuous rolls. Before battery cells can be assembled, these wide electrodes must be cut into narrow strips with precise dimensions. This process is called slitting. Although slitting appears to be…
🔋 iAtlas Battery #21 | ⚙️ Equipment → 🏭 Calendaring Equipment After an electrode has been coated and dried, it is not yet ready for battery assembly. The coating still contains microscopic pores, an uneven surface, and a thickness that may vary slightly across the electrode. The next step is calendaring—a precision roll-pressing process that…
🔋 iAtlas Battery #20 | ⚙️ Equipment → 🌡️ Drying Equipment After electrode slurry is coated onto copper or aluminum foil, the solvent must be removed before the electrode can move to calendaring and later cell assembly. This may sound like a simple heating process, but electrode drying is one of the most sensitive steps…
🔋 iAtlas Battery #19 | ⚙️ Equipment → 🎯 Coating Equipment Introduction Battery coating equipment is one of the most critical machines in lithium-ion battery manufacturing. After slurry is prepared in the mixing process, it must be coated onto a metal current collector with exceptional precision. Even tiny variations in coating thickness can reduce battery…
