With the rapid development of China’s new energy vehicle industry, automotive lithium batteries have entered the era of large-scale manufacturing.
The cost, technology, and manufacturing level of lithium batteries determine the cost, range, and performance of new energy vehicles, making them the core component influencing industry progress.
Pain Points in Lithium Battery Manufacturing
Due to the complex manufacturing process and numerous production steps, lithium battery production is generally divided into four major stages:electrode sheet production, cell assembly, cell activation and testing, and battery packaging. Each stage directly impacts battery performance.
Under dual pressures of cost control and policy direction, reducing production costs has become an urgent need for battery manufacturers.
Therefore, high efficiency, low energy consumption, and high precision automation have become the inevitable trend and foundation for achieving large-scale lithium battery production.
