In recent days the international crude oil prices falling, at present, the New York light crude oil has dropped below $80 a barrel level; And, the next two years rise in space may be limited. Reuters (Reuters) - a recent survey shows that more than one-third of respondents think that the north sea brent crude oil will be lower than $2013 in 100 (currently near $91 a barrel), nearly half of the respondents thought the north sea brent crude oil price is lower than $2014 in 100.
If analysts' forecast accurately, then the future a period of time that oil prices will remain at low levels. This will no doubt add difficulties to the development of electric vehicles, because the electric car relative fuel car of the economy will be on discount. As the most promising future lithium-ion batteries explosive source, electric vehicle development prospect is also affects the lithium battery and the development of upstream materials industry.
Of course, the main body of the lithium battery industry or consumer products. In this paper, the recent dynamic lithium battery of upstream materials industry development in our country some brief analysis. As is known to all, cathode materials, anode materials, electrolytes and diaphragm is the most important of the four lithium battery raw materials, which have been in the lithium battery industry plays an important role in the development.
The four materials not only focus, to improve the performance of lithium battery technology innovation and manufacturer field of fierce competition at home and abroad. Ternary material from a star in cobalt acid lithium, manganese acid lithium materials, three yuan, and the four main types of lithium iron phosphate lithium-ion battery cathode material, the material in the first half of this year three yuan (majority) nickel cobalt manganese acid lithium is undoubtedly the biggest star.
Three yuan in nickel cobalt manganese acid lithium materials, most domestic manufacturers choose a ratio of 5:2:3 (namely nickel, cobalt, manganese = 5:2:3). Using ternary material of lithium-ion batteries because have cost advantages, in addition to partly replace cobalt acid lithium is used in consumer electronics products, also is widely used in electric bicycles.
