In the past 2009, the large and medium-sized passenger car market has been sluggish. According to the statistics of the China Association of Automobile Manufacturers, large and medium-sized passenger vehicles showed negative growth throughout the year. However, in such a sluggish market, the statistics of China National Automobile Association show that the growth of other fuel buses is more obvious, with a year-on-year increase of 27.27%, including new energy buses , namely pure electric buses and hybrid buses. In the context of the promulgation of relevant policies for new energy vehicles and increasing incentives for consumption in China, the pace of industrialization of new energy buses has been accelerating rapidly in 2009. A data show that in 2009 the pure electric passenger car market has more than 100 vehicles and the number of mixed-use buses has reached 1,000. Experts predict that this data will surge this year as a result of policy encouragement. "In the second half of this year, 7 to 8 cities will also promote large-scale demonstration projects of new energy buses," said Ding Lixue, director of the Department of Electronics and Electrical Engineering at the National Engineering Laboratory for Electric Vehicles. By 2011, the number of new energy vehicles based on electric vehicles, hybrid vehicles, and hydrogen fuel cell vehicles in China will reach 500,000; and through the “Ten Thousand Cities†policy, tens of thousands of new energy buses will be launched on the streets of the city. . Therefore, a major issue related to environmental protection will be placed in front of the industry: At present, hybrid power and pure electric bus batteries mainly include lithium iron phosphate, lithium manganese oxide and other types, the electrolyte used in lithium batteries is organic matter, once released to the environment It will cause harm. However, there is no national standard for the scrapping of new energy bus batteries. With the increase in the number of new energy buses, the disposal of used batteries does not need to attract the attention of the industry. Waste battery pollution recycling standard is blank The battery is a key component of electric vehicles. Han Dongbao, senior engineer of Nanjing Iveco Product Engineering Department, said in an interview with reporters that lithium-ion batteries have high energy storage per unit weight, rich lithium resources, and low price, so lithium-ion and lithium-manganate batteries are widely used in new energy buses. . He said that despite a long period of development, lead-acid batteries have entered a mature period and were once widely used in electric buses. However, their shortcomings in volume, large volume, and large lead-acid pollution have gradually been taken up by bus companies. Deprecated. According to Ding Lixue, director of the Department of Electronics and Electrical Engineering of the National Engineering Laboratory for Electric Vehicles, "In accordance with national regulations, the number of rechargeable lithium iron phosphate batteries should not be less than 1,500, and the cycle charge of lithium manganese batteries should not be less than 500. The lithium iron phosphate battery is superior to the lithium manganate battery in terms of electric energy, number of recharges, and cost performance. Not long ago, reports on the environmental pollution of end-of-life batteries were reported in newspapers. One of the reports said that a small button cell can contaminate about 600,000 liters of water, which is equivalent to the amount of water a person spends in their lives; a No. 1 battery rots in the ground and can cause 1 square meter of land around to lose its agriculture. Use value. This inevitably leads people to think that whether the lithium battery installed on an electric bus will remain “zero emission†to the environment after being scrapped? The reporter reviewed a lot of information on the Internet. The general argument is that lithium is not a heavy metal and has almost no environmental pollution. However, an expert said in an interview with reporters that although lithium-ion batteries do not contain heavy metals such as mercury, cadmium, and lead, lithium-ion batteries, such as positive and negative electrode materials and electrolyte solutions, are still harmful to the environment and human health. have a great impact. Therefore, it is imperative that lithium batteries be recycled through standard methods to avoid recontamination of the environment. As lithium batteries that are currently scrapped do not belong to the hazardous waste specified by the state, this has virtually created a gap in the recycling management of used lithium batteries. The reporter found through interviews that at present, the state does not specify the disposal method of used lithium batteries. Wang Xianfeng, deputy secretary of the party committee of Ankai Automobile Co., Ltd., told reporters that when the national standard stipulates that the car battery saturation is less than 70% to 80%, it cannot be used for car energy storage. In order to reduce the user's single car purchase cost, Ankai and battery manufacturers and users adopt an annual fee-based battery lease method. The used battery will then be handled by the battery manufacturer. A staff member of Shenzhen Wuzhou Dragon Bus told reporters that the company has reached an agreement with the customer and the battery manufacturer before the sale. After the user purchases the electric bus for two years, the battery is recovered by the battery factory. However, it is unclear whether the manufacturers can provide the user with battery update service and pay for the recycling fee. It is also based on the technical level and product price after two years. However, experts said that as far as the bus industry is concerned, since the consumers of electric buses are mostly bus companies, it is not difficult to implement them if the corresponding standards are formulated. Foreign battery recycling subsidies At present, some developed countries abroad have carried out a series of active explorations in recycling waste batteries, and have accumulated a lot of good experience. For example, in the United States and Japan, spent batteries are recycled and processed by enterprises, and each ton of government pays a certain subsidy. In Korea, manufacturers of batteries produce a certain amount of deposit for each ton, which is used to pay for the costs of recyclers and processors. And designated a special factory for processing; other countries on the battery production companies to levy environmental treatment tax or waste battery processing companies for tax relief and so on. The reporter also learned through interviews that, from the current battery life, 3 years is basically the upper limit, and the normal life cycle of a bus that is put into operation is 8 years, which means that the new energy bus "lifetime" generally needs to be replaced 2 ~ 3 batteries, battery use and maintenance costs are quite high. It is said that the new energy buses operating during the Beijing Olympic Games cost only several hundred thousand yuan per battery. The high battery price is likely to become a stumbling block to the industrialization of new energy buses in the future. The main energy consumers of new energy buses - bus companies also hope that battery factories and manufacturing companies work together to find ways to reduce the company's re-expendable batteries. Ding Lixue said, "Only products with reliable performance and truly affordable users will be favored by users before they will become industrialized."
