Large-capacity lithium battery leads the industry

A wide range of haze weather affects people's daily life and physical health. Undoubtedly, the search for scientific governance of air pollution is a time of urgency.

The single 500-amp-hour power lithium battery pack can run 400 kilometers on a single charge, allowing a full-size bus to drive from Beijing to Shijiazhuang at normal speed. Talking about the new energy industry, lithium-ion vehicles are a rare history in China's fierce international competition. The future of lithium-ion batteries is just like today's oil. It has important strategic significance and is a strategic measure to ensure China’s energy security. Come to an "energy revolution" and "industrial revolution."

Environmental Issues Forced Industrial Transformation How to define the development of new energy in the world today, Wang Xiaogong believes that vigorously developing new energy industries will be one of the major breakthroughs China has made in solving energy and environmental problems and fulfilling its commitment to the international community.

At present, the global carbon dioxide emissions have exceeded 30 billion tons. The rapid economic growth has increased the demand for natural resources. Developing new energy is more urgent for China than any country in the world.

In order to accelerate the pace of new energy development, the country has introduced a series of preferential policies in the past two years. The International Energy Agency stated in the annual report of the Global Energy Outlook that China will surpass the United States in terms of energy consumption. The report predicts that China’s energy demand will double in 20 years.

It is understood that as early as 2009, the relevant national authorities proposed in the “Regulation of the Adjustment and Revitalization of the Automobile Industry” that by 2011, 500,000 new electric vehicle and other new energy vehicle production capacity will be formed. However, in fact, the output in 2011 was less than 10,000 vehicles. In 2012, five cities including Beijing, Shanghai, Shenzhen, Hangzhou, and Hefei proposed the goal of selling 20,000 to 30,000 electric vehicles, which has not yet been achieved.

Although global automobile powers have all introduced encouraging policies to support the development and application of new energy vehicles, global new energy electric vehicles generally account for only a very small share of the overall sales of automobiles. According to the data from the China Association of Automobile Manufacturers, sales of new energy vehicles in China were approximately 176 million in 2013, an increase of 37.9% year-on-year, of which 14,604 were sold by pure electric motors and 3,038 were sold by plug-in hybrids. After subtracting the city bus, the total sales of foreign brands in the country were only around 2,000.

"The new energy pure electric vehicle adopts single-capacity, solid polymer, power battery technology and industrialization, and the use of real-time monitoring of active battery management system after the installation of a pure electric bus is the key to breaking the constraints of the development of new energy vehicles." Say.

Wang Xiaogong believes that the "mistakes" in the popularization of new energy vehicles are based on the safety of pure electric vehicles. Many manufacturers of pure electric vehicles have to use the safety hazards of thousands of small-capacity parallel batteries, which has been deterring the marketization of pure electric vehicles. . The self-caused reason of short life, long charging time, and high cost of the battery, coupled with imperfect technical facilities and unmatched networks, has high charging and replacement costs, and consumers are inconvenient to use.

At present, the marketability of pure electric vehicles has become a new focus of international evaluation of national strength. Wang Xiaogong believes that the development of pure electric vehicles in China has at least the following advantages: First, to replace oil with electricity, reduce oil imports; Second, reduce harmful gas emissions, to complete the commitment to the world's carbon reduction indicators; Third, the comprehensive utilization of waste nightfall electricity (The energy can be driven by 30 million vehicles), with both social and economic benefits. As a core component of pure electric vehicles, lithium batteries have the irreplaceable advantages of other batteries at present and in the future for a long period of time. Monolithic large-capacity, solid polymer, and power lithium batteries are developed and industrialized in China. Success is of great significance to the development of new energy pure electric vehicles.

A keen eye to create a "new industry"

In 2001, Wang Xiaogong, who had studied and worked in the United States for more than a decade, returned to China and began hosting a project for a venture capital for overseas students. He hoped that Chinese students who have worked in the United States for more than 15 years, and have already returned to China with industry leaders who have achieved great success in all walks of life. Work, let them settle their own advanced technology in China's various industrial chains. A friend quipped that he always loves to do something that the government has to worry about. He said, "I must take it with courage!"

With the new round of financial turmoil triggered by the world energy crisis, countries have sought strategic energy security measures. At this time, Wang Xiaogong keenly discovered that pure electric vehicles have become a hot spot in international competition.

Wang Xiaogong's investigation found that more than 95 percent of the more than 300 lithium battery plants in China at the time were started from energy cell batteries for communication handsets. At the time, no one company had involved in the manufacture and application of single-cell high-capacity batteries. Grasping opportunities will undoubtedly help open up the situation and integrate into the market as soon as possible.

"As a source of power, batteries are the focus of new energy vehicle technology and industrial development, and are also the key factors that restrict the development of electric vehicles." Wang Xiaogong said.

The development of new energy industry is imperative. Wang Xiaogong calculated an account, assuming that the purchase of a pure electric bus is more than RMB 1 million compared with a conventional bus, but the application of a large-capacity Li-ion battery from Shenzhou is used to load a pure electric bus. The energy consumption per 100 km is 80 kWh. According to the bus mileage of 200 kilometers a day, then the daily power consumption is 160 degrees, then the night charging cost is 64 yuan, 8 years (340 days per year) operating electricity consumption costs is 174,000 yuan. Assuming that the daily mileage of a conventional fuel vehicle is the same, the daily energy consumption is 84 liters of gasoline per day, and the daily gasoline cost is 685 yuan. Then the fuel cost for the entire eight years of operation will be 1.8632 million yuan. Pure electric buses save operating costs of 1.6892 million yuan. If you consider the maintenance cost of pure electric vehicles, you will save more.

According to statistics, Beijing currently has about 22,000 urban buses and more than 60,000 taxis. If all fuel buses and taxis are replaced with zero-emission electric vehicles, the reduction will be equivalent to 6 million plants.

Regarding the development of new energy vehicles, Wang Xiaogong believes that compared to China, traditional auto giants are burdened with historical continuation and capital burden. They must not only adjust the industrial structure, but also deal with a large number of asset depreciation problems that have been invested in engine research and development and production. Therefore, they proposed 15 years of transitional speech. It can be said that with 15 years of hybrid vehicles, the gradual transition to pure electric vehicles, which is forced by the national conditions and to adopt a transitional approach.

If our country also follows the traditional car giant and slowly transitions from a hybrid car to a pure electric car, it is not worth the candle. Because the core technology of the traditional car engine is still monopolized by foreign countries, and battery technology to match the engine - the key technology is still subject to people. As a result, China's "leap-forward" development will become remote.

In light of the national conditions, Wang Xiaogong believes that in order to be technically unrestrained and completely independent, it is necessary to bypass the monopoly of traditional car engine technology and give full play to its advantages to directly develop pure electric vehicles. The industrialization of pure electric vehicles will be a rare historical opportunity for China in the fierce competition in the international auto industry. China has taken the lead in mastering the core technologies of the new energy pure electric vehicle power module, and it needs to be quickly marketized.
