According to Mr. Ma of the Battery Industry Association,  energy storage is used when electricity is low and electricity is released during peak times. The effective connection  between smart grids and lithium batteries is an efficient mode of resource utilization. The following Shenzhen Liyuan  disposable lithium battery manufacturers come to understand the situation with everyone.

According to data from the General Administration of Quality Supervision, Inspection and Quarantine,  lithium battery products now account for 40% of the global market share. In 2009 alone,  China exported 3.269 billion rechargeable lithium batteries with a total export value of 1.081 billion US dollars, China exported 3.269 billion rechargeable lithium batteries with a total export value of 1.081 billion US dollars, and exported 759.8 million disposable lithium batteries with a total export value of 508 million US dollars. Not only that, this group of numbers has been increasing at a rate of 20%-30% every year since 2006.

my country's hard-won market share should start in 1998. At that time,  the Tianjin Power Research Institute had just begun an attempt to industrialize lithium batteries,  so that when BYD Wang Chuanfu decided to enter the field of lithium batteries in 2000,  he had to go to Japan to buy equipment. But compared with it,  the research of lithium batteries in western developed countries can be traced back to the Edison era.

Consumers' recognition of lithium batteries starts with mobile phones. It is because of it that "Big Brother" can be  carried from his hands to his pockets. While shrinking in size, he also has a longer standby time. In fact,  lithium batteries have more brilliant achievements. For example,  it is because of the use of lithium subprimary batteries that cardiac pacemakers have the characteristics of low  self-discharge rate and smooth discharge voltage,  which makes the pacemaker implanted in the human body for long-term use. become possible.

Today, with the development of microelectronics technology,  miniaturized equipment is increasing day by day. Lithium batteries are everywhere in mobile phones, laptop computers,  power tools, street lamp backup power supplies, navigation lights, household appliances,  etc. Lithium batteries have rapidly eliminated battery technologies such as nickel-cadmium and nickel-metal hydride due  to their advantages of large reserves, light weight, rechargeability, and no pollution (excluding heavy metal cadmium),  leading the market.

Lithium battery development bottleneck

Like many industries in the past in the extensive economy,  the magic weapon for lithium batteries to quickly occupy the market is low cost. For this,  the helpless US government even compiled some "lithium batteries need to be packaged as dangerous goods" tricks,  trying to increase the cost and threshold of lithium battery exports. For the time being,  I don't care how outsiders mess up. In the rapid development of lithium batteries in just over ten years,  I also have more or less serious injuries.

Mr. Cao of the Battery Industry Association told the "Securities Daily" reporter,  "Aside from the materials and production equipment of lithium batteries,  the technical level of our national lithium batteries is synchronized with the international level. We have only  developed for more than ten years,  so this point is It's worth publicizing. But it also shows that in terms of technical level and production equipment, So this point is it's worth publicizing. But it also shows that in terms of technical level and production equipment, we are still led by other countries."

According to reporters' understanding, if the problem exists in production equipment and technology process, our country can also rely on imports and semi-artificial way to solve, even if the high cost of imported equipment, can still rely on low labor costs diluted. And in the production of lithium battery materials, such as diaphragm, battery surface steel shell stamping materials and other imports, not only the cost of sudden, and subject to other countries, but also to some poor quality imported materials to open the door, may in turn affect the brand image of lithium batteries.

In addition, because there are few self-owned brands of micro-electronic products, lithium battery enterprises mainly serve overseas customers, so every time the customers' products are adjusted, Chinese lithium battery manufacturers must change the relevant standards of the production line, and in many aspects, the requirements of overseas companies are very harsh.

Even so, the combination of international standards, imported materials, technical level and many other factors, lithium batteries still give people the impression of low-end, cheap. Pan Jing gave the reporter calculate a sum of accounts, "laptop lithium battery 18650 model of a cell, Samsung can sell to $3.65, and our company only sold $1.8, the enterprise production of such a cell profit can only reach 7% - 10%, compared to Samsung's profit can be imagined."

In terms of bottlenecks in the development of lithium batteries, Mr. Ma said, "Wind power and photovoltaic have very high requirements for lithium battery materials, such as high temperature resistance in desert environment, and low temperature resistance in offshore wind power." Pan Jing also told reporters, "Lithium batteries adapt to the environment of minus 20 degrees to 60 degrees, specific to the temperature difference between the north and south of China, will have some impact on the performance of the product itself." At the same time, the broader market has put forward stricter standards for the volume, repeated charging ability and fast charging ability of lithium batteries. After adapting to the volume and volume requirements of micro-electronic products, lithium batteries immediately have to adapt to the development of market demand and rapidly improve a series of technical indicators, which is itself a big problem.

Development prospect of lithium battery

Volume, materials and other technical upgrades, pointing to the hottest expected market demand - electric vehicles. According to a recent report released by Japan's Fuji Institute of Economic Research, the global automotive lithium battery market will expand by more than 200 times in six years. This will bring unlimited development space to lithium battery products, especially those lithium battery companies in the major automobile consumption countries.

Mr. Ma expressed his optimism about the technology upgrade. "With demand,  there will naturally be someone to develop. Under the adjustment of China's economic policy,  I believe that technology will soon have a breakthrough." Pan Jing also believes that "just like photovoltaic,  the national subsidy policy 1 After the introduction, companies from all over the world came to engage in solar energy,  and the speed of technology upgrades was quickly improved. Now the price of electric car batteries is really unbearable  for ordinary consumers,  and it is precisely because of the introduction of national support policies that many companies will respond to this  Products work hard."

The reporter was informed that the current endurance of electric vehicles is only 200-300 kilometers,  and charging takes 8 hours
