Introduction to the energy density and application of lithium cobalt oxide batteries

The energy density of lithium cobalt oxide batteries The energy density of lithium cobalt oxide batteries exceeds 150mAh/g in China, while the energy density of lithium cobalt oxide batteries does not exceed that in foreign countries. Lithium cobalt oxide battery has stable structure, high capacity ratio, outstanding comprehensive performance, but its safety is poor, and the cost is very high. It is mainly used for small and medium-sized batteries, and is widely used in notebook computers, mobile phones, MP3/4 and other small electronic devices. The nominal voltage is 3.7V. After long-term development in the application of lithium cobalt oxide batteries, four product lines have been formed for lithium cobalt oxide batteries: cylindrical batteries, polymer soft pack batteries, aluminum shell batteries, and steel shell batteries. These products are used in high-end and medium-sized batteries, respectively. High-end and low-end markets. 1. The high-end application of lithium cobalt oxide batteries is important for notebook computers. Because notebook computers have high requirements on battery capacity and safety, only cylindrical lithium cobalt oxide with good consistency can meet the application. Battery, and currently the only cylindrical lithium-ion battery manufacturers that can be accepted by international notebook computer manufacturers are Sony, Sanyo, Samsung and LG. Although many domestic manufacturers can also produce cylindrical lithium batteries in the past two years, it is difficult to enter the international first-line Dachang. 2. The most important mid-range customers of lithium cobalt oxide batteries are first-line brand mobile phones, digital cameras, mobile DVD, first-line brand Mp4, GpS and digital photo frame manufacturers. The sales of lithium-ion batteries of the four major domestic lithium battery giants and other large-scale manufacturers are mainly concentrated in this field. For mobile phones, Mp4s and digital photo frames, first-tier brands have much stricter requirements on the quality of lithium-ion batteries, but at the same time, first-tier brand customers’ profits will be higher and payments will be more punctual. These customers value the strength of battery companies and batteries. Quality. The most important demand for lithium cobalt oxide batteries in the mid-range market is soft pack batteries and aluminum shell batteries. 3. The low-end customers of lithium cobalt oxide batteries are mainly foreign trade-based Mp3, Mp4, GpS, digital photo frame manufacturers, domestic second- and third-tier mobile phone manufacturers, and counterfeit mobile phones. These manufacturers are mainly concentrated in the Pearl River Delta. The important needs are Steel shell batteries, but also some aluminum shells and liquid soft pack batteries are required. Most of the second- and third-tier mobile phone manufacturers and counterfeit mobile phone manufacturers are in domestic trade, and price is the most important competitive factor for their products; other Mp3 and other manufacturers are mainly foreign trade business, because they are at the lower end of their industrial chain, so the price is often the same. A factor they value very much. This customer group whose price is an important indicator is the target customers of two or three hundred small and medium lithium-ion battery cell factories or PACK factories scattered in the Pearl River Delta. This part of low-end customers often only pay attention to price rather than quality, and many companies have poor business reputation, which leads to low-end market battery suppliers not only with low profits, but also with high risks and fierce competition.
