The difference between soft-pack lithium battery and aluminum battery is mainly reflected in performance, application field and manufacturing cost.
In terms of performance, there are no technical barriers in the industry, and there are still many technical problems to be solved, especially in the index of battery cycle expansion, most cell factories have not solved this problem. The manufacturing automation degree of aluminum shell battery is higher than that of soft-pack lithium battery, so the influence of human factors on product consistency is reduced to a certain extent, and the labor cost is saved.
In terms of application field, the use of soft-pack lithium battery has advantages in areas with high consumption level, such as European and American countries. However, in most developing countries, such as India, the Middle East and other regions, aluminum shell battery has obvious advantages. The overlap is reflected in the high-end smartphone market, which is the most widely used market. For example, the use of flexible lithium-ion batteries represented by Apple and aluminum-shell batteries represented by Samsung is roughly equal. Among them, Samsung phones generally adopt a large size of 4.8 inches, with an average battery capacity of about 2700mAh, while apple's average battery capacity is around 1700mAh.
In terms of manufacturing cost, the aluminum-shell battery material has been completely domestically produced, while the aluminum-plastic film material for the soft-pack lithium battery still needs to be imported, and the technical requirements for the aluminum-shell battery material are lower than that for the soft-pack lithium battery. Therefore, at the same capacity, the overall material cost of aluminum shell battery is about 10% lower than that of soft pack lithium battery. In addition, the finished product processing is simple, reliable and cost advantage is obvious
