Wang Qi proposes to improve the recycling of used batteries

In the 2018 National Conference of the two countries, the 11th, 12th and 13th National People's Congress representatives of Sichuan Qiyang Automobile Group Chairman Wang Qi continued to compete with new energy vehicles, in accepting economic daily newspaper - China's economy When interviewed by the reporter, Wang Qi bluntly said, "At present, the entire battery recycling industry is still in its infancy. Individuals and enterprises are not paying enough attention to battery recycling. All parties concerned should take precautions to increase the recycling of new energy vehicle batteries and let new energy Cars can really help our blue sky defense battle."

Wang Qi and the new energy vehicle "competitive" suggest to improve the recycling of used batteries

In recent years, China's new energy vehicle market has been increasing in number. In 2017, China's new energy vehicle production and sales reached 794,000 and 777,000, respectively, ranking the world for three consecutive years, with a cumulative holding of 180,000 units. The global market has more than 50%. As one of the core components of new energy vehicles, the power battery has increased in volume. According to the China Chemical and Physical Power Industry Association data, the domestic new energy vehicle load power battery reached 37.06Gwh in 2017, an increase of 21.5%.

According to Wang Qi, considering that the service life of power batteries is generally 5 to 8 years, the new energy batteries that are promoted from 2009 to 2012 or vehicles with longer mileage are basically at the critical point of elimination. Some insiders said, "From 2018 onwards, the first batch of automotive power batteries entering the market will soon usher in the "retirement tide". This is similar to the prediction of the China Automotive Technology and Research Center. "Before 2020, China's pure The cumulative scrap of electric (including plug-in) passenger cars and hybrid passenger car power batteries will reach 12 - 170,000 tons.

Wang Qi revealed that from the current point of view, the recycling of batteries is not profitable. After the recycling, these raw materials can only be sold for 1/3 to 1/2 of the recycling cost. At present, there are two main recovery modes for power storage batteries: one is the use of the ladder, and the process of applying the used power storage battery (or the battery package/battery module/single battery) to other fields can be used at the first level or at multiple levels. The second is the raw material for the lithium battery that is reworked after disassembly.

If the used battery is improperly disposed during the recycling process, it will cause heavy metal pollution, alkali pollution and dust pollution, and electrolytes entering the environment, which will cause fluorine pollution and arsenic pollution. Scientific investigations have shown that the heavy metals of a discarded button cell are all dissolved in water and evenly dispersed, which can contaminate 600,000 liters of water, equivalent to the amount of water used by a person for a lifetime.

To this end, Wang Qi suggested: First, improve the management methods of used batteries, and establish a complete information system for used batteries. The battery manufacturer shall, according to the requirements of the state, serialize the power battery produced, and give the power battery “on the account”. The information system may be used to upload the serial number to trace the battery related information; the automobile manufacturer shall upload the new energy vehicle through the information system and The battery number corresponds to the information; the battery recycling company tracks the battery usage through the information system and number, and is responsible for handling and utilizing the battery.

Second, clear the waste battery management department and the main body of responsibility, the automobile production enterprise bears the main responsibility for the recovery of the power battery, and the relevant enterprises fulfill their respective responsibilities in the recycling and utilization of the power battery to ensure the effective use of the battery and environmental protection. If the used batteries are handed over to other units or individuals, dismantled and disassembled, and disassembled the power battery, resulting in environmental pollution or safety accidents, they shall bear corresponding responsibilities.

Third, carry out pilot projects for the recycling of new energy vehicles' power batteries, establish and improve the standard system for the utilization of waste power batteries, and ensure the effective utilization and safe handling of power batteries.

Fourth, the government should further improve relevant policies, such as implementing the responsibility mechanism, appealing to the attention of the society, enterprises and individuals, and giving corresponding support and subsidies to the battery recycling pilot in the policy.

Five, The State shall support scientific and technological research on battery recycling, guide industry-university-research collaboration, and promote innovation in battery recycling and utilization.
