Lithium battery materials industry: the road twists and turns a bright future

Small lithium battery industrialization in the 90s of last century, are now in a mature stage. laptop battery 70 years from the start of lithium batteries, but until the 90's safety have not been resolved, mainly because the use of lithium anode material, easy to explode. SONY Corporation until carbon as negative electrode material, the security issues have been resolved, since lithium batteries in computers, mobile phones, digital cameras and other fields to be popular
Traditional energy sources are depleting, power lithium gotten greater attention, the rapid development of cathode materials in the field. Small lithium use lithium cobalt oxide and carbon as the anode materials, but if used in new energy vehicles, the following problems: First of all, as the scarce resources of cobalt, high cost; second vehicle acceleration and deceleration in the process of bringing high-current charge and discharge , deposition of lithium in the anode, thereby supporting grain production, through film, causing the battery short circuit, the organic electrolyte under the conditions of high heat explosion. From the 90's, the United States invented Professor Goodenough lithium iron phosphate, the material properties of a good rate and high current density does not change the structure, allowing lithium batteries in the power of applications become possible. However, lithium iron phosphate is also an urgent need to solve many problems: low voltage (3.3V, lithium cobalt oxide is 3.7V),Latitude CPi low energy density

Although there are shortcomings in the current lithium power, but the problem can be solved in the development of the industry a great career ahead. Battery as a system, although the cathode material developed rapidly over the past few years, but the diaphragm, electrolyte, anode there are still many problems to be solved. 1) At present there are many kinds of anode material for lithium batteries, the most important is carbon, which apply more carbon-dimensional ball in the middle phase, this area has been the industrialization of Shenzhen Bei Terui. But the application of lithium in the power needed to solve a large current density of charging and the deposition of lithium in the anode material issues; 2) The application of the electrolyte can meet the small lithium, but lithium is still a force applied to its modified, flame retardant, etc. the research; 3) high-temperature polymer membrane obturator also need to avoid short-circuit and so on to improve. G5266 The short term, there are numerous power lithium, but Should the look long term, as the technology continues to develop industry a great career ahead

Fluoride short-term valuation is reasonable, long-term value remains to be seen lithium hexafluorophosphate progress of the project Fluoride current ex-factory price of aluminum fluoride in the 7500 yuan / ton, down again last week, a large number of primary and pre-stocking the downstream manufacturers; cryolite remain relatively stable In 6700 yuan / ton, we mentioned in previous reports, this year, because the rate of the downstream aluminum industry started a raise and some new capacity on stream, cryolite obvious gap in the short term needs. Inorganic fluoride for 10 years, 1.05 yuan, 1.38 yuan in 11 years the forecast, because first of all trades maintain a 10% increase, followed by the company with cryolite circulation process route and the anhydrous aluminum fluoride is expected to achieve cost-effective advantage of the growth above the industry speed; for lithium hexafluorophosphate, equipment installation is currently underway, according to the experience of Taurus, as lithium hexafluorophosphate special production process, devices also require non-standard transformation, transformation of results to be seen, so relatively large piece of business uncertainty.
