Dynamic lithium battery recycling road resistance and long

Writing Yang Zhiting's retired dynamic lithium battery is still a difficult problem. Since the beginning of 2014, my country's new energy vehicles began to enter the acceleration of corner overspeaking. It is reported that until 2020, my country's new energy car ownership has reached 4.

92 million, in which a considerable electric vehicle power lithium battery has entered a scrap period. According to China Auto Research Data, 2020 domestic dynamic lithium battery scrap has reached 200,000 tons. In the future, the scale of retired batteries will continue to increase, properly handle retired dynamic lithium battery recovery issues.

At the same time, it is also necessary to see the recycling of retired dynamic lithium batteries has a large market value: or will be used in the field of energy, and is applied to the field of energy storage; or disassemble it, recover metal materials such as nickel, cobalt. The above factors have prompted domestic cars and battery packs, etc. However, from the current actual situation, most companies that participate in the powerful lithium battery recycling are very small, and some even losses.

Why is the road of retired dynamic lithium battery recycling so hard, and the pain behind it is worth paying attention. 01 Inco-recycling channels are inconsistent, one of the difficulties of retired dynamic lithium battery recycling is not mature. "The retired battery should be to the leading company, but now it is not that the leading company adds 30% of retired batteries throughout the recovery.

"Hui Bao Wei, General Manager of Huayou Circulation. This can't help but want to ask: Other retired power lithium batteries? If you enter "Battery Recycling" on the Internet, then search, you can learn about the answer: The power lithium battery recycling advertisement on the Internet is nowhere. Most of these ads are some companies and individuals with some non-powered lithium battery recovery qualifications.

They can sacrifice the environment, reduce technical requirements, and recover the waste power lithium battery at a higher price. It is certain that the retired battery has flown into some unqualified, non-technical small companies, small workshops, these batteries are hard to handle, and because of the lack of technology, extensive treatment will bring great pressure to environmental protection. How to deport the retired dynamic lithium battery and how to guide retired dynamic lithium batteries into the company that meets the standardized conditions, is an important issue that the future power lithium battery recycling industry chain must consider.

It is worth noting that although the problem of recycling channel construction has not yet been completely resolved, some innovative models have made important "paving", such as the rise of new energy auto markets in recent years, in recent years. ". This "power-exchange mode" attracts companies including car companies, dynamic lithium batteries, third-party power saving operators and other companies.

At present, "power-saving mode" has made a lot of progress in the construction of electricity exchange stations, and the energy exchange efficiency, etc., and its advantages have gradually obtained the market recognition. It is worth noting that the core of the power-saving mode is to separate the car and the battery, and the ownership of the battery is no longer a user, but is attributed to the battery asset management company.

"Solving mode" allows the property of the power lithium battery to switch from the C-terminal to the B-terminal, making the centralized management of the power lithium battery become easier, and also establishes a smooth channel for the centralized recycling of the battery. 02 "Impractive" retired dynamic lithium batteries In addition to the recycling channels, the power lithium battery itself is "irregular" brought about by standard irregularities, and it is also a "blocking tiger" that is difficult to recycle the retired dynamic lithium battery. At present, due to the production process of dynamic lithium batteries, design ideas is not the same, and the use scenarios and different application models of their diversity, which caused a lot of power lithium battery, and the interface failed to completely uniform.

The "irregular" "irregular" of retired dynamic lithium batteries can result in extreme inconvenience when it is recycled, if automated disassembly is selected, and the flexible configuration requirements of the production line are high, and the treatment cost is added; if it is a manual dismantling, skill The level will affect the finished product rate in the dynamic lithium battery recovery, while in the process of manual disassembly, the waste-powered lithium battery is short-circuited, and the leakage can lead to a fire or explosion, there is a big safety and environmental hazard. It can be seen that the standardization of the power lithium battery will be an important factor in achieving efficient and secure recycling of retired power lithium batteries. But the reality is that although the state is accelerating the standardization of power lithium batteries, it is difficult to achieve complete unity due to the whole vehicle factory, battery factory and government departments and other relevant parties.

Can you solve the problem of "non-standardization" current "non-standardization" in the mode innovation? At present, the exchange mode is also a good hand in promoting the standardization of retired dynamic lithium batteries: due to standardized battery packs more conducive to Improve the work efficiency of the power transmission mode, so the power-saving mode has a strong "appeal" on battery standardization. Under the exchange of power transmission mode, the power lithium battery recovery will also become easy. For example, in order to achieve "new energy car shift network ecology", Silicon Valley Heaven is building a banking technology based on Boant Technology.

It is reported that standard modular batteries created with this technology can be applied to various models such as passenger cars, commercial vehicles. Specifically, based on this switching method, all models can be universal, a standard battery pack; according to different models and use scenarios, supporting different quantities of universal battery packs; universal battery packs can complete high-frequency bus within the power-saving station network The ladder of the low frequency vehicle will then enter the energy storage system. This allows for maximizing battery pack value without disassembling.

If the dismantling recovery of the general battery pack is involved, the dismantling efficiency is also high due to its standardized design. In summary, it is not difficult to find that there is currently an incisive channel of retired dynamic lithium batteries. In the face of these pain points, the current government, company, related research institutions, etc.

are also unremitting efforts, trying to explore some feasible, innovative ways to solve. Although the road of retirement dynamic lithium battery recovery is long, it is believed that under the multi-party efforts, the road to retired dynamic lithium battery recovery can be "smooth". .
