Application of lithium batteries in the field of backup power storage

The application of lithium batteries in the field of backup power storage. The existing energy storage libraries mainly include large-capacity energy storage, backup energy storage and household energy storage. On the basis of the existing technology, the cost performance of lithium batteries in the field of backup power sources has been significantly improved. Affected by markets such as new energy vehicles and backup power supplies, the market for lithium batteries will gradually expand. As far as power lithium batteries are concerned, it is expected to exceed 160 billion yuan in the next ten years. However, paying attention to the influence of upstream and downstream industries is a prerequisite for knowing the prosperity of shopping malls. In the possession of upstream lithium resources, there is an obvious oligopolistic competition pattern. SQM, Rockwood, FMC and Talison are the world's largest lithium miners, occupying more than 90% of the market. The lithium triangle region occupies half of the world's lithium resources, and its output accounts for more than 60% of the world's lithium resources. In March of this year, severe flooding occurred in the lithium triangle region, which seriously affected the processing of SQM in Atacama Salt Lake. SQM is the world's largest lithium processing company, accounting for 27% of the global market. Due to supply shrinkage, lithium prices rose sharply in the first half of this year. As of August 9, the price of industrial-grade lithium carbonate was 47,100 yuan per ton, a year-on-year increase of 27.3%. Recently, the price of lithium ore has reached US$480/ton. Since the second quarter, house prices have risen by 17%, which is significantly higher than the 10% annual increase in 2013-2014. There is still a big gap between my country's lithium battery technology and foreign countries. According to reports, the average energy density of Japanese batteries is 30%-40% higher than that of our country, and the number of times of equal capacity charging is several times that of our country. Currently, the global lithium battery technology center is dominated by companies from Japan, South Korea and other countries. Although local companies have increased their investments and efforts in technological research and development, they have not largely disintegrated. At present, my country's lithium battery data technology level is still very low, and most of its products are concentrated in the low-end and medium-end areas. Zheng xuehao said. The reason is that my country lacks corresponding technical support in the field of lithium batteries, and many products rely on the introduction of foreign technology. However, most of the imported skills are foreign middle- and low-end skills, and it is difficult to introduce high-end skills. However, my country itself lacks research on the high-end performance of lithium batteries. Battery barrier is one of the four major raw materials for lithium batteries, and the processing technology includes wet and dry processes. The legal obstacles in the dry field of the Prohibition Law are now relatively complex, and the more competitive wet method can completely replace import barriers. Faced with downward pressure on prices, according to the white paper on my country’s lithium battery barriers consultation recently announced. In the field of wet separation with high biaxial tensile strength and thinner thickness, my country is still in the early stage of import substitution. Future competition in the barrier industry will focus on wet barrier products. In other words, my country is also at a low level in the processing of lithium battery raw materials, and will face tremendous pressure in the future world competition.
