Raw materials for 2017: five Kings are fighting for lithium

The most popular word for the lithium battery material market in 2017 is "rise". In 2017, the market price of cobalt and lithium increased in varying degrees. Cobalt, in particular, has been from 47 since this month, according to Shanghai nonferrous data. 70,000 yuan/ton rose to the highest 51. 50,000 yuan/ton, up 10. 44%. According to the 51. The transaction price of 50,000 yuan/ton was more than 88% higher than the beginning of the year.

Symphony: destiny's opening point "rise and rise! Up and up!" In recent years, with the rise of the global electric car industry, the price of cobalt and lithium, an important raw material for lithium batteries, has risen. Because of mineral reserves and production capacity, rely heavily on overseas cobalt and lithium resources in China, the current domestic cobalt resources 90% dependent on foreign demand, with imports of lithium resource demand depends 70% on overseas imports. There is a forecast of 21 global demand for lithium carbonate in 2017-2020. 91, 25. 09 and 29. 300,000 tonnes, up more than 10 per cent year on year. According to industry data service provider Roskill to global lithium demand will reach 1 million tons in 2026, the compound annual growth rate will reach 18%, the main driving force comes from the battery industry, especially the new energy vehicle power battery industry. Thus, under the influence of the rapid development of new energy automotive industry, lithium gap between supply and demand will increase further, as a rare resource of lithium value will have room to improve further, prices will become the inevitable trend of the market.

Cobalt has a very low proven reserves, most of which are associated with other metal deposits, making the extraction and separation technology complex and the cost of extraction very high. According to industry media, about 60 percent of the world's current growth in cobalt consumption comes from China, which has become the world's largest consumer of cobalt. Global cobalt mainly concentrated in Congo (gold), Australia, and Cuba in The Three Kingdoms, as of 2016, Congo's cobalt (gold) proved reserves of 3.4 million tons, the world's first, and cobalt ore reserves in our country is only 80000 tons, cobalt ore reserves is extremely low. According to the statistics of relevant research institutions, China's cobalt consumption was about 4 in 2016. 580,000 tons, a year-on-year increase of 3. 78% of the time, the battery material consumption is about 3. 660,000 tons, accounting for 78% of cobalt's overall consumption structure. At present, the three - yuan battery has been favored by the market with higher than energy. The demand for cobalt has exploded, and the gap between supply and demand has been increased. The agency predicts that in 2016-2018, cobalt will have a gap of 1,000 to 3,000 tons per year in metallurgical fields. However, according to the research data of the institute, cobalt suppliers, including glencore, luoyang molybdenum and Eurasian resources, do not have much production capacity in the short term.

A variation of the song: "the trout's quintet" In fact, there are five forces in this annual "grab" show. The first is the domestic and foreign mining giant, they run for years, in the upstream mining in the hands of the rich resources of upstream, in the field of upstream has absolute power, to control costs and prices. The foreign SQM and FMC of lithium resources, the domestic tianqi lithium industry, jiangxi feng lithium industry and so on are the representatives of this aspect strength; There is data on cobalt that mining giant glencore, luoyang molybdenum, Eurasian resources and jinchuan group now account for 60 per cent of the world's cobalt production. Through the merger and purchase capital, mining giants to further enhance the control of global lithium cobalt resources, in lithium cobalt resources price so is present, firmly grasp the market initiative, to ensure that corporate profits.

The second force is the new energy car business. Considering the future development of new energy automotive industry, car companies are also added to the cobalt, lithium resources "grab" team, in order to reserve the upstream raw materials for the enterprise development in the future, try to participate in the negotiation system, cobalt, lithium resources to ensure that the enterprise for the future development of the initiative. Third force, new energy battery enterprises. Because of the lagging supply of cobalt and lithium, the supply and demand imbalance has led to frequent price fluctuations. In order to preempt the market and guarantee the supply of raw materials, battery enterprises have increased their control over the upstream resources. Fourth force, battery material enterprises. The battery material enterprises can be divided into three categories, one is the direct operation of the mining giant, such as: jiangxi feng, etc. The second is to focus on the material production of the company, such as: when promoted technology, fir shares, etc.; Third, the recycling of metal recycling enterprises, such as: green beauty and so on. This is mainly referred to the second type of material enterprises. The fifth force is all kinds of cross-border capital. Most of these businesses have built up in other fields, accumulating abundant capital. It is hoped that by tapping into the lithium electricity business, the distribution of rare mineral resources in the upstream will stimulate the growth of the company's business.

Sonata: "moonlight" "seek lithium for lithium" road insurance and long The personage inside course of study to the battery China said that while both at home and abroad in a "lithium cobalt" hot, but in fact the global lithium cobalt resources have long been demand, can buy the mines and equity few and far between. There is a way, "you have a good plan, I have a wall ladder", the enterprise to compete for the upstream resources is a total of the eight celestial crossing the sea each of the various. Chinese academy of engineering mian-ping zheng to battery China has proven reserves of lithium "salt lake" in China, qinghai salt lake lithium chloride is about 19.82 million tons, salt lake in Tibet has been find out the reserves of more than 1740, ten thousand tons of "salt lake lithium reserves are abundant in our country. "Salt lake" in the "s" has become the focus of enterprise in recent years, including byd, ningde hin high-tech era, countries, walter, Peking University first, noble shares, huatai battery industry chain companies such as car into qinghai, Tibet, "salt lake" industry rapid rise. 2017 is the first year of the "salt lake" industry. The production capacity of enterprises is gradually formed, and the lithium technology in salt lake is gradually maturing. The "salt lake" capacity acceleration will be the main focus of the "salt lake" lithium industry in 2018, expecting the release of "salt lake lithium" capacity to balance the increasing imbalance of lithium supply and demand.

International cobalt giant Cobalt27's recent "stockpiling" action has made the heart of new energy companies throb. Cobalt27 announced that it would issue c $85m (about 4 per cent). The common stock of RMB 3.7 billion is sold for 720 tons of high-grade metal cobalt. In fact, the company bought 2157 in June. 5 tons of cobalt, including 1486. 5 tons of high-grade metal cobalt and 671 tons of standard metal cobalt. On November 3, solstice, December 8, the price of the high-grade cobalt range in the international market reached 10% and 19%, while the price of the low-grade metal cobalt range increased by 8% and 7%. Cobalt-t27 announced that a big acquisition of cobalt was thought to be a major driver of the recent uptrend in cobalt prices. Insiders believe that Cobalt27 is more like an ETF for a cobalt product. The establishment of cobalt-t27 will transform the previously hidden stockpiling behavior into the listed ETF products, which will greatly expand the channel of social capital into the cobalt industry. Cobalt-t27's cobalt hoarding has been enough to affect global market prices, and if the cobalt-t27 is hoarded, it will push up prices.

The political situation in Congo, the world's largest cobalt supplier, has also made the fragile cobalt supply chain worse, with the exception of the cobalt price, which has led to a rise in cobalt prices. In January 2017, it was rumoured that Congo would ban the export of cobalt concentrate, and the price of cobalt at home and abroad rose. In October 2017, the government of the democratic republic of Congo issued a document banning the export of unprocessed copper and cobalt minerals, which again led to fluctuations in international cobalt prices. At the end of the year, Congo's domestic political turmoil is likely to trigger a return of the cobalt price, with little prospect of a stable price in the future.

Overall, 2017, high cobalt, lithium resources price rises all the way, for the whole of the development of new energy industry has formed a certain constraints, technical route selection of battery enterprises also caused a certain influence. In the case of rare mineral resources, enterprises actively compete for the position of the card, capital undercurrents surge. Regardless of the future of cobalt and lithium, battery China will continue to pay attention.
