Inner Mongolia Sanxin Technology Development Co., Ltd
Ternary material is one of my company's new project, I combined with the recent understanding of the ternary material, access to a variety of information on the characteristics of ternary materials, applications and their development in the country to do a simple Introduction and analysis. The three-element cathode material refers to a product such as lithium cobalt-manganese oxide (Li (NiCoMn) O2), a ternary composite cathode material precursor, and the like, and the ternary material described below refers only to nickel cobalt having the general formula Li (NixCoyMnz) Lithium manganate, is made of nickel salt, cobalt salt, manganese salt as raw material, the product is black powder, the proportion of nickel-cobalt-manganese can be adjusted according to actual needs. Can be used in small batteries and power batteries. Because of the advantages of both LiNiO2 and LiCoO2, the ternary materials are cheap and easy to synthesize. They are considered to be the new cathode materials which are most likely to replace the commercial LiCoO2. It is also a hot spot in the research of lithium ion batteries. Compared with lithium cobalt oxide, the ternary material has the following significant advantages: 1, low cost: due to less cobalt, the cost is only equivalent to 1/4 of lithium cobalt oxide and more green. 2, good security: safe working temperature up to 170 ℃, while the lithium cobalt oxide is only 130 ℃, a substantial increase in the use of security, is conducive to the safety of consumers. 3, grams of high capacity: the charge voltage at 4.6V (lithium cobalt oxide charge limit voltage of 4.2V), the grams of capacity to play up to 210mah / g, charging voltage at 4.8V, the grams of capacity to play up to 245mah / g, 1.7 times the lithium cobalt oxide, greatly enhance the battery's energy density and power supply time. 4, the battery cycle life extended by 45%. Ternary materials can be used for small lithium batteries and power batteries, despite the current market share is limited, but its development momentum is obvious. The use of ternary materials, small lithium battery has been gradually accepted by people, such as Dongguan huge Electronics Co., Ltd. produced a huge 14AQ002-03 type battery, using ICR18650-1S1P combination, the nominal voltage of 3.7V, the nominal capacity can be To 2200mAh, the standard continuous discharge current of 0.2C, the maximum continuous discharge current of 1C, charging the maximum temperature of 45 ℃, the trial, performance excellence. As the development of China's new energy vehicles has become an irreversible trend, ternary materials used in power lithium battery manufacturing will also become an indisputable fact, in August 2011, by the Shanghai New Energy Co., Ltd. production of high-performance Ternary material power lithium battery debut in Beijing. It is reported that the lithium battery is the introduction of Japanese technology production, will be put in the end of 2011 the domestic market. The company is about to put into production of ternary materials lithium-ion battery, the use of laminated flexible packaging, the battery energy density than the current domestic market limelight lithium iron phosphate battery 35% higher, will solve the electric vehicle driving range The problem is an effective solution. And lithium iron phosphate batteries, lithium cobalt oxide batteries, etc., ternary lithium battery has a lot of advantages, is more suitable for car lithium battery. At present, the ternary material lithium battery energy density can reach 160Wh / kg, has been significantly higher than other materials of the battery. In addition, its low temperature characteristics, power characteristics and high temperature storage is also better than other materials of the battery. With the continuous improvement of technology, ternary material lithium battery energy density will have a lot of room for growth. At present, the company has three companies with the vehicle business partners to develop and design power battery system. At the same time, also by foreign multinational companies concerned. In 2009, the global lithium-ion battery cathode material is still the largest market share of lithium cobalt oxide, accounting for 50%, followed by ternary materials, accounting for 39%, lithium manganese oxide and lithium iron phosphate materials were 6%, 5%. Among them, the lithium cobalt oxide cathode material market share than in previous years have a significant decline in ternary material market share is on the rise, the market share of lithium manganate becomes little, lithium iron phosphate as a new material began to gradually use the market , In the future with the power of lithium battery mass production, its use will be greatly increased. In 2009, the ternary material market was relatively sluggish and the gross profit was about 15% (as of the end of 2009, LCO 24 ~ 28W / T, NCM 17 ~ 18W / T). 2010 with the economic recovery, cobalt resource prices will gradually increase, ternary material relative to the competitive advantage of lithium cobalt oxide is more obvious, the market share will rise. Japan, South Korea some well-known battery manufacturers have been starting from 2010, the full use of ternary materials, lithium cobalt oxide will be fading out of the market, the domestic market in the long run, will also show this trend. Figure 1-1 market share of various types of cathode materials (2007 - 2011) Image Source: Battery Talent Network 2004 China's lithium battery industry began to contact and development of nickel-cobalt-manganese ternary cathode material. In 2005, some Chinese enterprises began to test the production of nickel-cobalt-manganese ternary cathode material, but in the cathode material market share share is very small. 2006 domestic lithium battery cathode material demand reached 20,000 tons, of which lithium cobalt oxide, lithium manganese oxide products accounted for 96% of the total market share, the two demand reached 19,200 tons. Nickel cobalt manganese ternary cathode materials accounted for less than 4% market share. 2007 - 2009 With the rising price of cobalt, lithium cobalt oxide prices also surged, domestic enterprises have used nickel cobalt manganese ternary materials to replace part of the cobalt lithium, ternary market share continues to increase, it is estimated that more than 15% The With the power tools and notebook battery market continues to expand, 2010-2011 ternary market share is still increasing, due to further rise in metal cobalt prices, is expected by the end of 2011 will exceed 1 million / ton mark, when the cobalt Lithium materials will face enormous cost pressures, thus, low prices and superior performance of the ternary material will further reflect the competitive advantage, to seize more market share. Japan and South Korea in the field of ternary materials in a leading position, the United States 3M company master ternary materials core patents, the current domestic enterprises have mastered the mature ternary material technology, the basic to meet the domestic market demand, but subject to patent issues, the current great Part of the market for cottage mobile phone / notebook, power tools, etc., it is difficult for supporting manufacturers, and exports have not been achieved. Japanese manufacturers to provide the quality of ternary materials in the world's best, the domestic involved in ternary materials, there are more than a dozen enterprises, of which the scale of the output of less than 10 enterprises, the market concentration is relatively high, dominant enterprises occupy a larger market share, Such as Yuyao Jinhe and Tianjiao technology, the two companies to provide the material process stability is better, production and share of the market share in the first, second, later difficult to catch up. Shenzhen Tianjiao Technology: Tianjiao technology was established in 2004, is the earliest master ternary materials core technology manufacturers (their production of the former body), has now developed into the domestic lithium battery material strength of the leading integrated supplier: 2010 sales of ternary materials 2200 tons (capacity of 3,000 tons), 550 tons of lithium manganese oxide, electrolytes 220 tons (July 2010 production, production capacity of 6,000 tons), and made lithium titanate industry standard development rights. Ningbo Jinhe: the company with an annual output of 1,000 tons of lithium cobalt oxide, nickel cobalt (manganese) acid lithium 1500 tons, in addition to meet the major domestic battery manufacturers, but also exported to Japan, South Korea, with TDK, LF, Samsung, Tianjin God, Tianjin Bamor, BAK, Lenovo and a number of strategic customers, integrated market competitiveness in the same industry-leading position. Hunan Shanshan: The company is co-founded by Ningbo Shanshan Co., Ltd. (75% of the shares) and Central South University (25% of the shares). Was established in November 2003, the registered capital of 50 million yuan, the total investment of nearly 300 million yuan, high - tech enterprises in Hunan Province. Ternary material current production capacity of 500 tons / year. Chongqing Terry: the company for the high-tech enterprises in Chongqing, the registered capital of 20 million yuan, the company mainly produces and sells lithium battery cathode materials, the current production of products are TR-101, TR-202 nickel cobalt manganate (ternary positive Materials), the current production capacity of 800 tons / year. The synthesis method of TR-101 with high circulation, high capacity and high pressure was awarded the national invention patent on July 16, 2008. Patent No .: 200610031706. The new lithium industry: the company was founded in 2008 with a registered capital of 10 million yuan. January 15, 2009, the company modified lithium manganese oxide and nickel cobalt manganate annual production capacity of 500 tons of production line officially put into operation. Become the first domestic and foreign production of micron-level single crystal ternary materials manufacturers. Beijing when the rise: the company is now ternary materials, lithium cobalt oxide, lithium manganate each 1/3, ternary material annual capacity of 1,200 tons. Hunan Ruixiang: to the United States 3 OEM. Salt light technology: the company master 532 ternary material sintering technology. Ternary material applications by sub-use, for digital communications batteries, laptop batteries, power tools, batteries, power bike / car batteries. From the regional point of view, digital communications batteries, notebook battery production mainly distributed in the Pearl River Delta region, with a wide range of battery manufacturers, customer base wide, from top to bottom source of supply and demand matching, complete and other characteristics; ternary material market is very large. Power tools batteries, power bike / car battery manufacturers are relatively scattered. Mainly concentrated in Shandong, Zhejiang, Henan Area. This type of battery manufacturer's battery output may not be large-scale communications battery manufacturers, but because of the high capacity of single cells, larger, means that the demand for raw materials can not be ignored. In the communications battery, the last 3-5 years, the dominant position of lithium cobalt oxide will gradually weaken, there may be lithium cobalt oxide and nickel cobalt manganese ternary material coexistence phenomenon, 5 years later, may be nickel cobalt manganese ternary material Dominate the times. In the field of electric tools, nickel-cobalt-manganese ternary materials with high energy density, good high-current charge and discharge performance, excellent cycle performance and safety performance, may become the main cathode material. In the field of power batteries, phosphate-based cathode materials, lithium manganese oxide, nickel-cobalt manganese ternary material may replace lithium cobalt oxide as a new generation of positive electrode active material.
