Power lithium battery recycling industry -Lithium - Ion Battery Equipment

The first batch of new energy vehicle power batteries put into the market in my country will soon usher in a centralized scrapping period. According to data released by market research institutions, in 2016, the scrapped power battery in my country was about 12,000 tons, and by 2020, this number is expected to surge to about 248,000 tons. The centralized "retirement" of used power batteries has brought a window of opportunity to the recycling industry.(Lithium - Ion Battery Equipment)

However, it is not easy to realize this "benefit". Immature technology, non-standard processing, and inadequate supervision may erode development dividends. It is imperative to establish a mature and efficient recycling system.

"Scrap wave" brings opportunities for power battery recycling industry

The Shenzhen Municipal Transportation Commission announced that, in addition to retaining some non-pure electric vehicles as emergency transport capacity, all the city's franchised public transport vehicles have been fully electric. By 2020, Shenzhen will also achieve 100% electrification of taxis.

This is a microcosm of my country's move towards a big country in the production and sales of new energy vehicles. Since 2014, my country's new energy vehicle market has shown a rapid development trend. As of the end of 2017, the number of new energy vehicles in the country reached 1.53 million.

However, another fact worthy of attention is that the on-board power battery will usher in a centralized scrapping period in the next few years. "Our analysis believes that after 2018, the scale of domestic retired power batteries will increase rapidly." said Bai Min, an assistant researcher at the International Economic and Technical Cooperation Center of the Ministry of Industry and Information Technology.

The recycling of waste power batteries is of great significance: on the one hand, it can improve the level of recycling of battery raw materials, and on the other hand, it can avoid potential harm to people and the environment caused by waste power batteries.

A person in charge of a new energy vehicle manufacturing company told reporters that, unlike lead-acid batteries that contain heavy metals and are toxic and harmful in the past, lithium batteries commonly used in new energy vehicles are relatively less harmful to the environment. Copper, cobalt, lithium and other metals in batteries have higher economic value. Under the regulation of the market mechanism, waste power batteries will be favored by recycling companies. "Lithium batteries are full of treasures, and I'm not afraid that no one will handle them."

"Economic accounts" cannot be simply calculated, beware that industrial opportunities become social problems

——Immature industrialization technology squeezes profit space. Zhang Changling, a senior engineer at China Automotive Technology Research Center, believes that at present, key technologies such as power battery retirement judgment standards and detection technology, residual value evaluation technology of batteries that can be used in cascade, automatic dismantling of single battery and material sorting technology are not mature enough. Battery recycling companies still use manual dismantling or traditional recycling processes. According to estimates, a power battery recycling enterprise using traditional technology, recycling 1 ton of waste lithium iron phosphate power battery is not only unprofitable, but may lose money.

- Improper handling of lithium batteries has the risk of explosion and pollution. Zhang Zheming, an assistant researcher at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, said that lithium batteries are relatively environmentally friendly, but that does not mean that they will not cause harm to the human body and the environment during processing. When the battery is depleted to a certain extent or after a collision during transportation, a short circuit may occur, which may easily cause the battery to explode.

——The flow of some batteries lacks supervision, which can easily lead to "bad money drives out good money". Information from the Ministry of Industry and Information Technology shows that since 2015, China Tower Corporation has built 57 decommissioned battery cascade utilization test sites in 9 provinces and cities including Heilongjiang and Tianjin. Various usage scenarios such as backup power, peak shaving and valley filling, and microgrid. However, Bai Min reminded that some used power batteries may also flow to informal recycling companies. Through simple dismantling, these companies resell some of the batteries to users in other fields, such as low-speed electric vehicles and electric toy manufacturers.
