What are the lithium battery industry chains?12 volt deep cycle marine battery

　　1. Upstream resources

　　Lithium resources mainly include two parts: first, salt lake brine lithium, lithium chemical products produced from salt lake brine extracts are mainly lithium carbonate and lithium chloride; the other is lithium ore, and lithium ore products are sorted from ore are mainly splendid Stone, lithium Yunmu, etc. Most of the salt lake resources are in South America (Bolivia, Chilean high -altitude regions) and China (Qinghai -Tibet Plateau). Among them, Salt Lake resources in South America are basically in the hands of SQM, FMC, and Rockwood. 62%of the global lithium market supply. Ore resources are mainly distributed in Australia, North America and China, of which Australia has the highest quality and the largest reserves. Tyleson has the world's largest spale pyroxyl in ore production.

　　According to the US Geological Survey (USGS) data, the global lithium resource reserves of 13 million tons in 2012, of which Chile 7.5 million tons, accounting for 57.7%, China 3.5 million tons, accounting for 26.9%, Australia 1 million tons, accounting for 7.7.7 %, Argentina 850,000 tons, accounting for 6.5%.

　　With the development of the lithium battery industry, many companies have invested in the development of lithium resources, mainly including Tibet Mining, CITIC Guoan, Luxiang Co., Ltd., Western Mining, Salt Lake Group, etc.

　　1. Tibet Mining: The Zabeye Salt Lake, which is mined by the company, is one of the three major lithium salt lakes in the world, with the second in the world, with potential resource value of 150 billion yuan; Tibet Mining strives to achieve the long -view target of 25,000 tons of lithium carbonate products within 5 years Essence

　　2. CITIC Guoan: Qinghai Guoan has 3,000 tons of lithium carbonate production capacity and is planned to build 35,000 tons; its holding subsidiary Lang Guli (90%) has 1500 tons of lithium drill acid and 500 tons of lithium manganate production capacity; In comprehensive projects, its total lithium chloride resource reserves of 7.6385 million tons, lithium chloride taste

　　2.2 ~ 3.89 grams/liter; CITIC Guoan currently invest a total of 20,000 tons of lithium carbonate projects.

　　3. Lu Xiang Co., Ltd.: Ganzi Rongda Lithium, which is acquired by the company, has the "Asian First Lithium Mine" 呷 矿 ore ore 134 ore ore vein of 5114 million tons of lithium ore mining rights, which also controls nearly 30 million tons of Salian Pyrantite Mine underground , Lithium Lithium reserves ranks first in the country, ranking first in Asia and the second in the world.

　　2. Breakthrough of key materials in midstream

　　The performance is doubled and the cost decreases, mainly by materials. More than 70%of the battery cost is composed of materials, and the battery performance is also determined by the material.

　　It should be composed of five parts, that is, positive electrode materials, negative materials, electrolytes, diaphragm and packaging materials. Among them, packaging materials and graphite negative technology are relatively mature, and the cost is not high. The core materials of lithium -ion batteries are mainly positive materials, electrolytes and diaphragms. Among them, the positive pole material is the decisive factor for the electrochemical performance of lithium ion battery. The proportion of positive materials accounted for more than 40%of the cost of lithium battery, which is the most important part of the component, electrolyte and diaphragm, with the cost of 10%and 20%, respectively.

　　At present, in the four major key materials areas in China, the positive poles, negative materials and electrolytes have been gradually self -sufficient. Only the diaphragm materials are highly dependent on imports, but the development speed is also very fast.

　　Positive material

　　The market for lithium battery positive materials is mainly occupied by lithium diamond, ternary material, lithium manganate, and lithium iron phosphate. According to statistics from the Japanese lithium battery industry research institution IIT, lithium drill acid is 49%of the positive electrode materials in China, 22%of the three yuan materials, 16%of lithium manganate, 6%of lithium iron phosphate, 7%of other materials account %.

　　At present, the commercialized positive materials on the market only have lithium drill acid. However, from the perspective of performance, the number of lithium diamonds is low, and the heat stability of the crystal structure is poor. There are large hidden safety hazards, which is only suitable for small batteries. The number of lithium iron phosphate reaches more than 2,000 times, low price, non -toxic and environmental protection, and the performance of ternary materials and lithium manganate is also better than lithium drill acid. Two mainstream technical directions of areas and large -capacity power supply.
