Mr. Cao of China Battery Industry Association shows, carries on stored energy at the time of the low ebb of electricity consumption, release the electric energy at the time of the crest value, the connecting effectively of intellectual electric wire netting and lithium cell, it is the most efficient mode of utilization of resources
The data display of State Bureau of Quality Testing, at present, lithium cell that China is the maximum of the world produces the manufacture base, the second largest lithium cell producing country and exporter, market share that the lithium-battery products have already accounted for 40% in the world. In only 2009, will export and can charge 3,269 million lithium cells, total export is 1,081 million dollars at home, export 75,980,000 disposable lithium cells, total export is 508 million dollars. Moreover, this group of figures are here with 20%& mdash every year from 2006 to the present; 30% of the speeds increase.
This hard-earned market share of our country would be spoken of since 1998. At that time, the research institute of power of Tianjin had just begun the attempt of industrialization of lithium cell, today has already been " The richest " BYD Wang biography good fortune 2000 determine to march into by lithium-battery at the time of the fields, be must go to Japan to buy by apparatused. But compared with it, the study on lithium cell of western developed country can trace back to Edison times.
Chinese consumers begin with the mobile phone to the cognition of lithium cell, because have, it, " The mobile telephone " Could hold on pocket carrying in hand, while the volume decrease, have long standby time also. In fact, lithium cell has more brilliant achievements, for example, the pacemaker because uses lithium inferior galvanic battery, having just had a characteristic of low, mild in discharge voltage self-discharge rate, make the human long term administration of implantation of artificial pacemaker become possible.
Today, with the development of microelectronic technology, miniaturization apparatus increases day by day, mobile phone, notebook computer, electric tool, street lamp back up supply, portable lamp, family expenses light electric apparatus first-class, etc, see the figure of lithium cell everywhere. Lithium cell, according to light and handy, can charge repeatedly, the pollution-free (cadmium excluding the heavy metal) large in reserves Co dominant, eliminate nickel-cadmium, nickel-hydrogen the intersection of battery and technology rapidly, monopolize the market the intersection of Ao and hair.
Lithium cell develops the bottleneck
Like a lot of industries in extensive economy in the past, the magic weapon that Chinese lithium cell can capture the international market rapidly is the low cost too. The U.S. government of what is as to this has no way out even arranges out some " Lithium cell needs to pack according to the dangerous cargo " Trick,manage to last cost sum threshold. Go, ignore how do mischief stranger, the intersection of Chinese and in short ten over year develop fast, lithium cell for the moment, have more or less hard wound too oneself.
Mr. Cao of China Battery Industry Association tells reporter of " daily report of the securities ", " The material which bypasses lithium cell talks to fabrication facilities no, the engineering level of lithium cell of our country is and synchronous in the world, we are just development of several decades, so this point is worth propagating. But prove, in such aspects as engineering level and fabrication facilities, we are led by the nose by the other countries at the same time. "
As far as reporter know, if the problem exists in fabrication facilities and technological process, our country can also rely on and import and half an artificial way is solved, even if is the great amount of import equipment cost, can still rely on cheap staff costs to carry on the stand thinly. In material for producing lithium cell, if diaphragm, battery appearance steel shell ram materials etc. to also depend on import, not only the cost grows, and is situated in the other countries, give some imported materials with low quality and open the hole even more suddenly, influence the brand image of Chinese lithium cell conversely finally.
In addition, because there are few independent brands of the little electronic product, lithium cell enterprises serve more overseas customers, so each adjustment of customer's products, the lithium cell manufacturing enterprise of our country must change and produce the collinear relevant standard, and requirements in the overseas company are all very harsh in many aspects. New energy Company of the sail of Baoding (the only wholly-owned constituent company of storage battery of sail) Pan Jing, assistant manager of market department, tells reporter of " daily report of the securities ", " The customer's requirement must be observed, our company nearly passes all international current authentication standards. "
Even so, comprehensive international standard, importing the factor in many aspects such as materials, engineering level,etc., , low priced primary impression that lithium cell of China gives somebody the low-end. Pan Jing has calculated an account for the reporter, " A electric core in the type of notebook computer lithium cell 18650, Samsung can be sold for 3.65 dollars, and the enterprises of our country are only sold for 1.8 dollars, profit that Chinese enterprises produce such a electric core can only reach 7%& mdash at most; 10%, by contrast, can think of but the cicada at three stellar profits. "
In bottleneck of one's own development of lithium cell, Mr. Cao says for example, " Wind-powered electricity, photovoltaic have very high expectations for material of lithium cell, such as able to bear the high temperature behavioring under the desert environment, and then electric low temperature resistant characteristic of wind such as the offshore. " Pan Jing tells reporters too, " The acclimation of lithium cell is & mdash 20 degrees below zero; 60 degrees, the temperature difference reaching the North of our country and southern, will play some influence on own characteristic of the products specifically. " Meanwhile, broad market to the intersection of lithium cell and volume, charge ability, charge ability, get rigorous standard out of fast repeatedly, and just met lithium cell after the requirements for volume, volume of little electronic product, at once must compliance the developments of market demand,getting which promote a series more of fast for technical indicator, this itself is a great difficult problem. 1 2More information can be found article-top at
