China is the world's motorcycle production and sales of the first big country, China's motorcycle production in 1993, the first time in Japan, the Chinese motorcycle market is still in peak demand, the electric motorcycle is a large potential market, the field opened up for the lead-acid batteries a huge new market. Motorcycle industry is currently opening the battery is still used in the main, but opening the battery is sealed battery replacement is an inevitable trend, the current amount of motorcycles has only 10 to 11 vehicles / thousand, while the international standard for the 20 / thousand far, the motorcycle production will grow steadily.
Communication with the lead-acid batteries.
China's post and telecommunications industry is currently in a period of rapid development, the scale of the average annual growth of more than 20%, fixed asset investment has been for 7 years more than 100 billion yuan. Not long ago, in fact, according to the most authoritative source of statistics of domestic phone users reached 460 million, including fixed telephone and mobile phone users half and half, more than the "fifth objective" figures, is expected in the next 20 years, China will be the world the largest telecommunications market.
Communications industry is the main user lead-acid batteries, VRLA batteries in particular accounts for two-thirds of the total market demand. Medium and small sealed batteries in postal system, the main application areas for users to access and Communication Network. Subscriber access network is the Ministry of Information Industry, "fifth" period is an important direction of development, beginning in 2000, the development of this area showing a strong momentum, especially in Beijing, Shanghai, Guangdong, Jiangsu and other economically developed areas and large, in the city, have put into this advanced communications network, as the information economy continues to develop, market potential in this area.
Power batteries.
The power industry is focused on the development of basic industries, 1998-2002 average annual installed capacity of 20 million kW or more, over the years, the urban and rural power grid construction and transformation of inadequate investment, resulting in delay in the power grid construction, urban and rural areas with limited electricity demand and consumption. To increase the electricity restructuring, power must be adjusted capital investment, accelerate the pace of urban and rural power grid construction and transformation. 1998 to 2000, the state power companies to invest 380 billion yuan for urban and rural power grids, the power shift focus from building power grids. 2000 to 2005 a year for the western and eastern parts of the follow-up of urban and rural power grids supporting investment projects will reach 80 billion yuan.
4, rail diesel and electric locomotive batteries.
China in recent years on increasing investment in infrastructure, railway construction is one of the key infrastructure. "Fifth" during the country's total investment in the railway system will reach 360 billion yuan, the battery is in great demand, to the end of 2002, the number has more than 12,000 diesel locomotive, electric locomotive of 4600.
5, UPS batteries (small and medium density).
UPS is an uninterruptible power supply systems, mainly supporting the use of computers and precision instruments, the core part of its batteries. In recent years, with the popularity of computers in our country, UPS market was driven up accordingly, UPS developed rapidly in China.
6, electric vehicles and electric bicycle batteries.
6.1 electric vehicles.
With China's economic development, fuel surge in car ownership, vehicle emissions as a major source of urban air pollution is one, for the implementation of the Chinese Government takes environmental protection as an important part of sustainable development strategies, the state in 1996 to start the car major science and technology industrialization projects, including concept development, research the key components of electric vehicles (battery, battery management, etc.). As the electric vehicle battery research there are many different lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries, sodium - nickel chloride batteries, lithium ion batteries, fuel cells. According to the Chinese electric vehicle development program, expects to buses, taxis, electric cars as the primary status, and therefore need to develop low-cost electric vehicle batteries, electric vehicle in 1991, the state will lead acid battery research and development as a priority project, the current The biggest problem is the poor battery uniform consistency.
6.2 electric bicycle batteries.
