Worries about waste battery recycling: in 2018, the scrap volume of power lithium battery will exceed 170,000 tons

The development of new energy vehicles starts from the original intention of the exhaustion of petrochemical energy and the reduction of environmental pollution. However, if the problem of waste battery recycling is not solved well, it will cause environmental pollution and break away from the original intention of developing new energy vehicles. Have to say, look from current home circumstance, near worry already appeared.

Thirteen years ago lead-acid batteries were the mainstay of power batteries. Today the battery industry is very different. Is not hard to find, as electric bicycles, electric cars, mobile phones, such as the products are widely used, lithium ion battery increased year by year, mercury batteries have withdrawn from the civilian market, waste battery type and quantity of the great changes have taken place in a dozen years ago, compared to the environment risk can not be ignored, such as waste lead accumulator randomly dump acid, in the process of recycling waste lithium ion battery burst into flames.

Battery recycling space is huge

In particular, the rapid development of new energy vehicles, the rapid development of the lithium battery industry. According to the survey, the warranty period of electric vehicle battery sold in the market is generally 5-8 years / 10,000-150,000 km. As a general rule, the normal attenuation life of the battery should be roughly set at this point. According to the widely spread view in the industry, people generally regard 80% as the node of battery capacity and range attenuation.

According to experts' analysis, China's recycling market for power lithium batteries will take shape in 2018, with a cumulative scrap volume of more than 170,000 tons. The recycling market for cobalt, nickel, manganese, lithium, iron and aluminum will exceed 5.3 billion yuan, and 10 billion yuan by 2020.

According to the China automotive technology research center, by 2020, China's only pure electric (including plug-in) passenger cars and hybrid passenger cars power battery scrap volume will reach the scale of 120 to 170 thousand tons. According to wu feng, a professor of energy and environmental materials at the Beijing institute of technology, there are an estimated 25 billion used lithium batteries in the world by 2020.

Worries about battery recycling

Of market space big, blue sea enlarge capacity fast, the world is infrequent. However, China's recycling of used batteries has no clear responsibility constraints, and the recycling system is very imperfect. A large number of waste batteries flow into informal channels, causing environmental threats. At the same time, informal recycling enterprises have cost advantages because they do not take environmental protection measures, which also makes the formal recycling enterprises face the embarrassing situation of insufficient waste battery materials.

What is the solution to waste batteries? According to the analysis of the industry, apart from increasing research and development investment, breaking through the technical bottleneck of disposal of waste power batteries and finding a feasible path that is both environmentally friendly and economical, we should also focus on the recycling link:

On the one hand, we should first explore the technical standard of unified battery, so as to lay a foundation for large-scale unified recycling in the future. On the one hand, policies and regulations should be introduced to clarify the main body of battery recycling responsibility and related responsibilities, and at the same time, appropriate subsidies and encouragement should be given to recycling enterprises. In addition, private battery dismantling activities should be strengthened to strictly control the flow of batteries into informal channels.

, chairman of National People's Congress on behalf of day Zhang Tianren also suggested that the need to "increase waste lithium batteries and dismantling, restructuring, key technology research for test and life prediction and improve technical maturity and the safety of the production process, as well as the automation level and recovery efficiency, power lithium battery recycling economic feasibility and safety.

"Apart from the government's attention, the recycling of waste batteries requires the general public to enhance their awareness of environmental protection." Wang jian, a senior engineer at the dispatching center of Sichuan electric power company, believes that the government should publicize it through newspapers, television and other media to raise the public's awareness of the duality of batteries and increase their awareness not to throw them anywhere.
