Aluminum shell lithium-ion battery and soft pack lithium-ion battery are different

The use of soft pack lithium-ion battery packs has advantages. In most sectors of the country's growth, such as India, the Middle East and other regions, aluminum shell batteries have obvious advantages. Coincidence table of application scale At the moment, the most widely used high-end smartphone market, the soft-pack lithium-ion battery represented by Apple and the aluminum shell battery represented by Samsung as an example, the usage of the two is basically equal to half. Among them, Samsung mobile phones generally recycle a large size of 4.8 inches, with an average battery capacity of about 2700mAh, while the average battery capacity of Apple mobile phones is about 1700mAh. There are no technical barriers in the industry, and soft-pack lithium-ion battery packs currently have many technical difficulties to be solved, especially in the battery cycle expansion index, most battery cell factories have not yet dealt with this problem. The automation level of aluminum shell battery manufacturing is higher than that of soft-pack lithium-ion batteries. Therefore, the impact of wage factors on product consistency is reduced to a certain level, and labor costs are reduced at the same time. From the perspective of manufacturing, the materials for aluminum-shell lithium-ion batteries have been fully localized, while the aluminum-plastic film materials for soft-pack lithium-ion batteries still need to be imported, and the technical requirements for battery materials of aluminum-shell batteries are lower than those for soft-pack lithium-ion batteries. Therefore, under the same capacity, the overall material cost is about 10% lower than that of soft-pack lithium-ion batteries. In addition, the product processing is simple, reliable, and the cost advantage is obvious. The quality and energy density of soft-packed lithium-ion batteries is higher than that of aluminum-shell batteries. For batteries of the same size, soft-packed lithium-ion batteries are about 10%-20% lighter than aluminum-shell batteries. On the one hand, mid-to-high-end electronic consumer products are becoming thinner, thinner, and more integrated, and the demand for battery energy density and product appearance is increasing. Soft-pack lithium-ion batteries have the potential to replace aluminum shell batteries under the conditions of gradual advancement of technology maturity. , The advantages will be further highlighted. Aluminum shell lithium-ion battery recycling laser sealing process, while soft-pack lithium-ion battery recycling hot-melt technology, the sealing performance of aluminum shell batteries is better than soft-pack lithium-ion batteries, preventing aging and air leakage at the seal; soft-pack lithium-ion batteries The burst pressure of the battery is much smaller than that of the aluminum shell battery, due to the recycled aluminum-plastic composite film packaging. Aluminum-shell lithium-ion batteries have an overall value advantage, and the company’s initial capital investment will be lower than that of soft-pack lithium-ion batteries. Soft-packed lithium-ion batteries are mainly targeted at the mid-to-high-end market, and the profit margin of unit products is higher. Under the same output conditions, the relative profit is higher than that of aluminum shell batteries, and the capital return period is also short.
