As we all know, any electronic products are inseparable from the power battery drive; China Electronics Show (CEF), as the largest electronics show in China, has always been an important display of power batteries. Why do we need a separate CEF power show (/power/index.shtm)?

In the face of energy consumption is high and the limitations of traditional energy reserves, President hu jintao on June 7, 2010, at the Chinese Academy of Sciences academy members conference speech which explicitly mentioned, "as a rapid development of industrialization and urbanization, the population of country, energy resources and ecological environment in our country, particularly prominent contradiction, promote sustainable development task is particularly hard." To this end, seven strategic emerging industries have been identified in the Outline of the 12th Five-Year Plan: new-generation information technology, energy conservation and environmental protection, bioengineering, high-end equipment manufacturing, new energy, new materials, and new-energy vehicles. It can be seen that almost all of the seven strategic emerging industries are closely related to power battery technology. For the battery industry based on electronics and new materials, the power supply industry with power electronic devices as the core is itself a part of the strategic industry. With the development of new materials, new generation of information technology and other industries, battery technology, power electronic devices, power management technology are upgrading, which directly promotes the development and upgrading of battery power industry. In particular, the development of energy conservation and environmental protection, new energy, new energy vehicles and new generation of information technology industries directly depends on the technological progress and product update of the power battery industry, and the development of the power battery industry has created an unprecedented huge market.

Challenges are also opportunities. Undoubtedly, the objective situation forces mankind to explore new forms of green and energy-saving energy on the basis of efficient utilization of traditional energy. At present, the technical progress of power supply and battery industry is very active, and new products and technologies spring up after rain. Solar cell, lithium ion power battery, fuel cell, new module power supply, digital power supply, wireless charging...... In response to the request of many exhibitors, the 77th CEE will be dedicated to the No.6 Hall as the "new green energy-saving and efficient" power supply, battery products demonstration area.

As the first power battery industry exhibition after the spring of 2011, this exhibition leads the development of the industry. Let's analyze the highlights one by one:

1. Rapid growth of new energy industry

In the field of new energy, solar cells are developing at an unexpected speed. According to scientists, a conservative estimate, in the next 10 years, the average conversion efficiency of solar cell to reach more than 20%, but the price to fall by half, which is 10 years later, we can half used for lighting electricity from solar energy, that is, from solar cells to leds, implementation from PN junction to the p-n junction real green lighting.

In recent years, China's solar photovoltaic cell production and market sales have been growing at an average annual rate of 15% and 20%, respectively. Last year, China's solar cell production reached 2.4 megawatts, a record high. Experts predict that in the next three to five years, China's total solar photovoltaic cell production will soar to 15-20 megawatts.

On December 8, 2010, delegates to the Global Wind Energy Council meeting in Cancun, Mexico, said that by 2020 wind power could meet 12% of the world's electricity demand, helping to reduce global carbon dioxide emissions by 1.5 billion tons a year.

The market for solar inverters (photoelectric inverters) is growing due to the demand for renewable energy, and these inverters require extremely high efficiency and reliability. This opens up a new market opportunity for semiconductor manufacturers for power diodes, power switches, etc., which are critical for improving the conversion efficiency of inverters.

Geared to the needs of new energy field, CEF power exhibition will focus on display for power system of electric power transformation equipment, power supply units in the service of environmental protection and human health, suitable for the need of information society power supply products, thin - light - microminiature power module and device as well as the high efficiency and energy saving low pollution "green" power supply products so that some of the mainstream of the 21st century power supply products.

2. New energy vehicles and new energy storage components go hand in hand

On January 11, 2010, China Association of Automobile Manufacturers released the statistics of China's automobile production and sales in 2009, which showed that China surpassed the United States for the first time by more than 3 million vehicles and became the world's largest automobile production and sales country, 5 to 6 years ahead of the original estimate. China has become the world's major auto market. Formulating or accelerating the implementation of policies to support new energy vehicles and supporting the development of the electric vehicle industry has become a top priority. The Ministry of Science and Technology will further increase investment in R&D of electric vehicles, continue to support and lead the development of electric vehicles in China, and seize the opportunities in the next five to 10 years to make China a powerful country in energy saving and new energy vehicles. At the same time, fuel cell vehicles become the future to occupy the global market commanding heights. In the near future, China will develop energy-saving vehicles and hybrid electric vehicles to realize the transformation and upgrading of energy-saving technologies for traditional vehicles. By 2020, China's industrialization and market size of new energy vehicles are expected to be the world's first.

The booming development of new energy vehicles has led to a boom in the lithium battery market. Data show that the global sales of lithium battery materials in 2009 has reached $3.39 billion. If a pure electric vehicle needs 40 to 50 kilograms of cathode materials and electrolyte, which is about 10,000 times of the consumption of a single mobile phone battery, then the lithium ion battery related materials needed to produce only 1 million electric vehicles will be several times of the current global total demand for lithium battery materials. Over the past year or so, new investment in the industry has turned to lithium-ion batteries.

Not only new energy vehicles, the application of wind energy, solar energy and other new energy also need to vigorously develop energy storage components, but also put forward an ardent development demand for the battery industry.

So, we saw this lively scene: Many industry-leading lithium battery manufacturers are racing to sign up for CEF power exhibition focused on such as lithium ion battery technology of new energy, kay is committed to high polymer lithium battery of shenzhen ShengWei power co., LTD., in addition, the brocade of power lithium battery power management system, shandong chi xiang new energy technology co., LTD., cylindrical lithium-ion batteries, as the new energy vehicles, Applications such as power tools and energy storage power supplies bring a wider range of options.

This exhibition not only has the development and utilization of new energy, but also has the efficient development and utilization of new technologies of traditional energy. The show gathers the best in the industry. Energizer battery, which has composed numerous number one batteries in the battery industry, is still the leader in the industry. This time, it will appear in the special booth of No.6 theme exhibition hall.

3, energy saving, environmental protection new devices are popular

"Green energy conservation, environmental protection and efficiency" is reflected in every pavilion of the 77th China Electronics Expo. LED products, as the direct users of battery-power devices, are distributed in the No.4 theme hall of the 77th China Electronics Fair. The theme of "green" is not only to reduce the power consumption of products, but also to reduce the production and use of substances harmful to human health. For example, the backlight CCLF (cold cathode fluorescent lamp) used in traditional LCD TVs contains mercury, which is harmful to human health, while LED backlight technology can achieve green lighting, which does not contain mercury, in line with the green and low-carbon trend. At the same time, LED backlight is also very power saving, the internal driving voltage is much lower than CCFL, power consumption and safety are better than CCFL. CEF will be attended by LED companies such as Star Source Electronics Technology (Shenzhen) Co., Ltd., which is very competitive in the field of LED backlight and backlight components.

LED is also inseparable from the support of power products, for example, LED drive power needs to challenge higher conversion efficiency, especially when driving high-power LED, which puts forward higher requirements for power and battery exhibitors located in Hall 6. They have launched corresponding solutions for LED applications.

The theme pavilions also echo each other at the 2011 China (Shenzhen) Consumer Electronics Show (CCEF), which was held in parallel with the 77th China Electronics Show. CCEF focuses on the theme of low carbon and energy saving, displaying a variety of 3C consumer electronics terminal products. Obviously, smart terminals in the mobile Internet, Internet of Things and cloud computing environment put forward higher requirements for battery life. And efficient energy saving power supply, so that our household appliances, consumer electronics, lamps and lanterns environmental protection more efficient, so that our future life is better.
