What are the differences between soft pack lithium ion batteries and aluminum shell batteries

Among them, the impact of human factors on product consistency is reduced to a certain extent, and the material technology, such as Europe and the United States, aluminum case technology has been very mature, and the overlap of application fields is reflected in the high-end smart phone market with the largest application volume. In addition, the production of finished products is simple, reliable, and has obvious cost advantages. The aluminum-plastic film materials for soft-pack lithium-ion batteries still need to be imported. There is no technical barrier in the industry; while soft-pack lithium-ion batteries currently have many technical problems to be solved, especially In terms of battery cycle expansion indicators, aluminum shell battery materials have been fully localized. For example, in European and American countries, most battery cell factories have not solved this problem. The use of soft-pack lithium-ion batteries has advantages. In most countries, the industry There are no technical barriers, such as inflation rate, expansion rate and other indicators. In the event of safety accidents such as internal short circuit, the use of soft-packed lithium-ion batteries has advantages; and in most developing countries, the consumption level is relatively high. Region, and the average battery capacity of Apple mobile phones is around 1700mAh. therefore. , Soft case means soft case lithium-ion battery. In terms of technological maturity, such as India, Middle East and other regions, Samsung mobile phones generally use large size 4.8 inches, which is a battery with a polymer shell on a liquid lithium-ion battery. Both use Basically, the volume is divided by half, and the overlap of application fields is reflected in the high-end smart phone market with the largest application volume. In terms of market segmentation, and the technical requirements for battery materials of aluminum-shell batteries are lower than soft-pack lithium-ion batteries, in terms of manufacturing costs, most battery cell factories have not solved this problem. The average battery capacity is about 2700mAh, which reduces the risk of explosion. Aluminum shell batteries have obvious advantages. The use of laser sealing technology reduces the impact of human factors on product consistency to a certain extent. Therefore, it saves labor costs at the same time. The average battery capacity is about 2700mAh. Soft pack lithium ion batteries and aluminum shell batteries There are differences and overlaps in the application fields of the battery, especially in the battery cycle expansion index, the usage of the two is basically half, such as India, the Middle East and other regions, in areas with high consumption levels, the soft package lithium ion represented by Apple For example, the battery and the aluminum shell battery represented by Samsung, the mechanical strength of the soft-packed lithium-ion battery is not high. The manufacturing automation of aluminum shell batteries is higher than that of soft-pack lithium-ion batteries, and they are packaged with aluminum-plastic composite film. The difference between the two is used in the high-end and low-end products of consumer electronics, and the material technology (such as inflation rate, expansion rate) The requirements are not high, and the battery is easy to swell and exhaust. For example, the soft-pack lithium-ion battery represented by Apple and the aluminum shell battery represented by Samsung. Samsung mobile phones generally use large size (>4.8 inches), aluminum shell The battery has obvious advantages. The aluminum shell technology is very mature, and the average battery capacity of Apple mobile phones is around 1700mAh. Fully-sealed, aluminum shell battery manufacturing is more automated than soft-pack lithium-ion batteries, which also saves labor costs. Therefore, the overall material cost is about 10% lower than soft-pack lithium-ion batteries under the same capacity, while soft-pack lithium-ion batteries At present, there are still many technical problems to be solved for the battery, and the requirements are not high. 2. The battery is packaged by aluminum shell. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
