Statistical analysis of market size and output of China lead-acid battery industry
2017/11/23 view:
Lead-acid batteries are mainly composed of tubular cathode plate, cathode plate, electrolyte, clapboard, battery trough, battery cover, pole column, injection liquid cover and so on. The electrode of the exhaust battery is composed of the oxides of lead and lead, and the electrolyte is the aqueous solution of sulfuric acid. The main advantages are voltage stability, cheap price; The disadvantage is that the energy is lower than the energy (that is, the battery storage per kilogram), the service life is short and the daily maintenance is frequent. Old-fashioned ordinary batteries typically live for about 2 years, and periodically check the height of the electrolyte and add distilled water. But with the development of technology, lead-acid battery life has become longer and easier to maintain.
The most obvious feature of a lead-acid battery is that the top has a plastic seal that can be unscrewed and a vent hole. These liquid caps are used for filling pure water, inspecting electrolytes and discharging gases. In theory, lead-acid batteries need to check the density of the electrolyte and the height of the liquid in each maintenance, if there is a need to add distilled water. However, with the upgrading of battery manufacturing technology, lead-acid battery developed to lead-acid maintenance-free battery and colloid maintenance-free battery, lead-acid batteries do not need to add electrolyte or distilled water. The main use of the cathode to produce oxygen can be absorbed in the negative electrode to achieve oxygen circulation, can prevent water loss. Lead-acid water batteries are mostly used in tractor, tricycle, car start-up, and maintenance-free lead-acid batteries, including the application of a wider range of uninterruptible power supply, electric vehicle power, electric bicycle batteries. The lead-acid battery is divided into constant-exile electricity (such as uninterruptible power supply) and instantaneous discharge (such as car start-up battery) according to application needs.
Lead-acid battery has no other battery to compete with the characteristics, such as high performance price ratio, good security, low self-discharge, especially the maturity of its recovery technology, lead recycling use of high utilization of the obvious advantage. As a kind of energy products with high resource recycle, lead-acid battery belongs to the industry which consumes resources. The mainstream enterprises of the industry has already changed the past high pollution production status, has realized the product technology "low consumption" and manufacturing equipment "energy-saving", embarked on a cleaner production road. Lead-acid batteries contain $number recyclable plastics and lead, and the recycling of these materials is beneficial to both users and the environment. So, for a long period of time, lead-acid battery is still the main product of two battery, and the demand in many fields is increasing.
With the development of automobile industry and the increasing of car ownership, the market demand of lead-acid battery in automobile is increasing. In the current era of competition to develop hybrid electric vehicles, with reliable and raw materials recyclable characteristics, lead-acid batteries may become the preferred.
In recent ten years, China's lead-acid battery industry gradually from a small scale, manufacturing technology backward low-end industries, has developed into 2000 enterprises, the total output value of 170 billion yuan of the large industry. Authoritative data show that China's current production accounted for One-third of the world's total. At present, the industry is dominated by small and medium-sized enterprises, forming a pattern of industrial concentration areas such as Zhejiang, Fujian, Guangdong and other economically developed areas.
Booz data released "2017-2022 China lead-acid battery market depth research and investment Prospects report", 2015 China lead-acid battery industry sales market scale of about 163.97 billion yuan, 2014 years 172.28 billion yuan fell 4.82%, In recent years, the market scale of lead-acid battery industry in China is as follows:

2009-2015 China Lead-acid battery industry sales Market Scale
With the sustained and rapid economic development, China's automobile, communications, electricity, railway transportation, information, radio and television industries to maintain a rapid development trend, the demand for lead-acid batteries has been increasing, greatly promoting the development of lead-acid battery industry. In 2014, the production of lead-acid battery in China reached 220.6977 million kvah,2015 years, the production of lead-acid batteries was 210.1483 million KVA and 4.78%. Among them, the demand of automobile starter battery, electric bicycle battery, communication base Station battery, wind power and solar energy storage lead battery are increased obviously.

The growth of the market demand of lead-acid batteries mainly benefited from the rapid development of downstream industries, and the development of lithium-ion power batteries under cathode materials has not been developed rapidly. Automotive, electric bicycles, mobile phones, digital products, notebook computers, toys and electric tools and other battery products traditional market will continue to grow rapidly, $number network construction to accelerate, pan in the network, things networking gradually into the commercial, smart grid construction, the implementation of three-network integration, solar energy, The development of new energy industries such as wind and electric vehicles will bring huge market demand to lead-acid battery industry.
