Review of the development history of lithium battery technology

Review of the development history of lithium battery technology Judging from the development trend of lithium battery positive electrode data at that time, it is in the process of evolving from lithium cobalt positive electrode data of consumer electronics to dynamic lithium battery. From the data point of view, it is a road map for cobaltization. At that time, in the dynamic lithium battery positive data, the three technical routes of lithium manganate, ternary data, and lithium iron phosphate formed a competition pattern of the Romance of the Three Kingdoms, each with its own supporting company community and technology development ecosystem. Career development of lithium battery cathode information The lithium battery industry continued to rise in 2011. The global lithium battery industry is expected to rise in 2011. Despite the macroeconomic decline in 2011, the global lithium battery market continues to grow under the large-scale concentration. According to the statistics of CCID personnel, the global lithium battery market is planned to reach 15.3 billion U.S. dollars in 2011, an increase of 29.7%, which is a year-on-year increase of global lithium batteries. The output value reached 4.64 billion people, an increase of 22.8% over the previous year. Yesterday, from the four-year trend in the bag, the rise in the lithium battery industry has been relatively stable after 2008. In 2011, the planned growth rate of my country's lithium battery market was higher than the global growth rate. According to data from CCID employees, my country’s lithium battery professional market plans for 2011 is 39.7 billion yuan, a year-on-year increase of 43%, and the annual lithium battery output value is 2.97 billion yuan, a year-on-year increase of 28.6%. According to the data of the past 4 years, the rise rate of my country's lithium battery industry is about 10 to 13 percentage points higher than that of the world, showing a rapid upward trend, which is consistent with the professional setting of lithium battery capacity. The data ratio of lithium manganate and lithium iron phosphate has increased significantly. From the perspective of the growth rate of positive electrode data storage, in 2011, my country’s lithium battery positive electrode data sales increased by 33% year-on-year, higher than the world’s 29% growth rate. In the product structure of positive electrode data, the proportion of dynamic positive electrode data such as lithium manganate and lithium iron phosphate has been significantly increased. In 2008, the domestic sales of lithium iron phosphate accounted for only 1.8%, which rose to 6.01% in 2011. The proportion of lithium manganate data has increased rapidly, from 6.92% in 2008 to 12.61% in 2011. From the perspective of the product share format of the entire cathode data, the rapid rise of dynamic cathode data such as lithium manganate and lithium iron phosphate has significantly reduced the market share of lithium cobalt oxide cathode data. Skills circle, use pull: positive data The Romance of the Three Kingdoms format judging from the development trend of lithium battery positive data at that time, it is in the process of evolving from lithium cobalt positive data of consumer electronics to dynamic lithium batteries. From the data point of view, it is a road map for cobaltization. At that time, in the dynamic lithium battery positive data, the three technical routes of lithium manganate, ternary data, and lithium iron phosphate formed a competition pattern of the Romance of the Three Kingdoms, each with its own supporting company community and technology development ecosystem. The road of three skills is carried out by prehistoric recall of nickel-cobalt-manganese ternary data to adjust the data ratio, so that the application range spans high energy density consumer lithium and electric lithium. The development of nickel-cobalt-manganese ternary data has gone through three stages: the first stage was in the 1990s. The ternary chemical composition of lithium nickel-cobalt-manganese oxide was obtained through solid phase doping. The advantage is a simple synthesis process, low cost, and disadvantages. Mechanical stirring and solid phase sintering are difficult to achieve the standard of uniform atomic distribution, and the electrochemical function of the product is poor. Now this industry has abandoned this application. The second stage is the beginning of the 21st century, the use of hydrogen and oxygen precursor system to prepare spherical secondary particles. Its advantage is good electrochemical performance, but its disadvantage is that manganese ions are easy to oxidize and the process is difficult to control. On the other hand, the secondary particles are easily broken during electrode rolling, resulting in low compaction density.
