Is the waste lithium ion battery useful, how to "turn waste into treasure"?

　　Author ：Iflowpower – Portable Power Station Supplier

Generally speaking, the warranty period of the power lithium battery is 5-8 years. At present, the first invested electric vehicles on the market began to enter the replacement period, and the peak period of lithium-ion battery has also arrived, and how will it face batch retired battery companies? Disposal, there is still no complete solution still. However, at the Resource Recycling Expo held in Tokyo this year, a senior executive of Honda Motors said: The company plans to use waste lithium-ion batteries as raw materials to start producing nickel-cobalt alloy.

Relevant institutions predict that the lithium-ion battery to be recovered from Japan in Japan will be increased to 500,000 sets to the 2025. Down cost promotion The current electric vehicle has become the development of the world's new energy vehicle, but if the battery is not perfect, it will not only cause waste, but also bring extreme environments and safety hazards to society. According to the European Auto News Network, Honda Motors announced in Geneva Auto Show.

By 2025, all new cars sold in Honda in Europe will be pure electric or hybrid models. Up to now, the 14 mixed passenger models produced by Honda have a total sales volume of 26%, and 747,177 were sold in 2018. Tomokazuabe, general manager of Honda Motor Company Circular Resource Promotion Department, said: By 2030, Honda may generate 300,000 vehicles with lithium-ion battery.

Note: For reference but if 300,000 cars with a lithium-ion battery have no set of recycling plans for the battery, then another environmental pollution will occur. According to the market price of 2017, a Fit (FIT) car can recover nickel and cobalt materials worth 4,000 yen (about 36 US dollars, 239.2 yuan).

So far, the company's nickel recovery rate is 99.7 &, cobalt recovery is 91.3%, and manganese recovery is 94.

8%. However, due to the limited battery supply, the lack of mature recovery technology, leading to the low cost of recovery. Thus, Honda wants to produce nickel-cobalt alloy through a cathode of the waste battery, and the secondary processing of the alloy is sold as a metal hydride.

The goal is the hydrogen storage market. In addition, it is also possible to reduce recovery costs by controlling transportation costs and disassembling the car using robots. According to industry insiders, the hydrogen storage tanks of Japanese steel are composed of metal hydride alloy, which consists of 60% nickel, 30% lanthanum and ruthenium and 10% silicone resin.

It is necessary to use 4 tons of such an alloy in a hydrogen storage tank having a diameter of 4,200 mm and a height of 550 mm. This market prospect is worth looking forward to. Of course, far more than one company begins to solve the problem of recycling of lithium ion batteries.

Last year, the Japanese Automotive Manufacturers Association is building a recycling model of retired lithium-ion batteries throughout the industry. This project includes Toyota, Nissan and other Japanese automotive manufacturers. They envisaged that the car disassembly outlets will be dismantled from the retired battery after receiving the use of used electric vehicles, and the processes are processed to the recycling plant.

Automotive manufacturers will pay fees to Japan's automobile circular utilization collaborative institutions. Tesla CTO Sterlabell proposed that Tesla will recover battery raw materials in the super factory. Tesra has a planning of battery recovery, and there is also a clear business direction.

Super Factory integrates the supply chain, which is ideal for battery dismantling, recovery from raw materials, to re-use. Last year, Tesla has developed a 1.04GWH energy storage business, almost three times the 2017 358MWH energy storage business, reaching a new milestone.

Domestic accelerated battery recycling once the scrap dynamic lithium battery enters the outbreak period, it is likely to bring difficult to abrasive disasters. Do not recovering lithium-ion batteries will cause secondary pollution, but the cost of recovery is difficult to reduce, etc., in front of the recycling company.

The latest data from the "Investigation Report" shows that my country's power storage battery has more than 131GWH, and the industrial scale is ranked. On the supporting type, lithium iron phosphate and ternary batteries respectively account for about 54%, 40%, respectively. At present, the biggest difficulty in battery recovery includes the technical bottleneck to regenerate and utilization still needs to be broken.

The recycling system has not yet formed, and the recycling and utilization is difficult. In this regard, the state has to improve the supporting policy support system, introduce diversified incentives, only allow the company to taste the sweetness, play the market main use, can accelerate the recycling system, forming multi-parties. In fact, last year, my country Tower has stopped the purchase of lead-acid batteries, and ladded by a ladder by about 120,000 base stations in 31 provinces and cities.

In addition, the State Grid also tries to build a 1MWH ladder, using a phosphate ion battery energy storage system demonstration project, which is used to accept renewable energy power generation and frequency modulation. As for the retired battery, the "Electric Vehicle Power Battery Recycling Technical Policy" issued by the Five Ministers has been clearly regulated, that is, who is responsible, who pollutes who governs?. This also means that the powerful lithium battery production company and automobile production should take responsibility for the recycling of lithium battery.

According to guidance, automotive manufacturers are building recycling systems in a variety of forms. At present, 45 companies such as Beiqi New Energy and Guangzhou Auto Mitsubishi have established 3204 recycling service outlets. It is important to focus on the region of Beijing-Tianjin-Hebei, long triangle, Pearl River Delta and central energy vehicles, and is important to 4S shop.

Present. Regarding the recycling company, the source of retired dynamic lithium batteries must be guaranteed to a certain extent, broadcasted the recycling channel, which is conducive to promoting its marketing, and the recycling of regular recycling companies. And recycling technology, etc.

The foreseeable trend is that although car companies play the subject's responsibility, more recycling will be borne by third-party companies. It is proposed that important recycling outlet layout mode can be divided into self-owned sales channel construction recycling network mode and a third-party recycling company to jointly build recycling network mode. Among them, the self-owned sales channel construction recycling network is mainstream, and it is important to rely on the dealer's 4S store to carry out corresponding recycling, about 80% of the company adopted this model.

According to the planning of the Ministry of Industry and Information Technology, it will make full use of industrial foundation such as existing scrap vehicles, electronic electrical disassembly and non-ferrous metallurgy, and coordinate the power storage battery recycling company to promote sustainable development of the industry. Through the policy and market company, multi-partial power supply battery recycling, the future is expected to form a complete and standardized industrial chain. Industry faucets will also come out.

At present, the dynamic lithium battery industry leading Ningde Times has acquired Guangdong Bang Pubei through its subsidiary Ningde and Sheng shareholding and capital increase. Guangdong Bangp is a business scope including battery material production, processing, sales; development and transfer of waste secondary battery recovery technology, etc. Through this acquisition, the company will enter the industrial chain to a lithium-ion battery recycling business.

At the two sessions, the National Committee of the Chinese People's Political Consultative Conference, Academician, my country Academy of Engineering, Chen Xiaohong, the president of Hunan Business School, improve my country's power storage battery recycling system and industry standard, optimize related industrial technology, and establish a power storage battery forced recycling system. From the perspective of status quo, my country's dynamic lithium battery recycling is still in an emerging field, and in its starting stage. Although the state has introduced a number of policies, the powerful lithium battery forced recycling system has not yet established, industry standards are not perfect, and the technical system is not strong enough and also become a problem that is constrained.

Don't wait until the scrap battery is flooded, it is realized that new energy vehicles are far more no environmentally friendly than fuel vehicles. Honda's mixed passenger models are equipped with lithium-ion batteries. On March 1st, Tomokazuabe, the general manager of the resource recycling fair (ResourceRecyClingexpo), Tomokazuabe, general manager of Honda Automobile Corporation, said: From 2025, Honda will recycle a large number of waste lithium battery, when we Will be ready to add.

At present, Honda produces 14 mixed passenger models. According to Honda, its hybrid vehicle sales account for 26% of its total sales, and 747,177 vehicles sold in 2018. ABE also said: By 2030, Honda may generate 300,000 vehicles with lithium-ion batteries.

Honda's plan is to produce nickel-cobalt alloys using a cathode of waste batteries. The goal is to hydrogen storage market. ABE said: According to the market price of 2017, from a Fit (FIT) car, we can recycle nickel and cobalt materials worth 4,000 yen (about 36 US dollars, 239.

2 yuan). So far, the company's nickel recovery rate is 99.7 &, cobalt recovery is 91.

3%, and manganese recovery is 94.8%. ABE talks: people are worried that nickel and cobalt materials will be short, and they are worried that the recovery cost will be reduced after a few years.

ABE estimates that the cost of recovering metal from waste batteries is 100 yen per kilogram (about 5.98 yuan). However, the recycling company's insiders said that because the battery supply is limited, the lack of mature recovery technology leads to the low efficiency, the current cost is higher.

ABE indicates that the recovery cost can be reduced by controlling the cost of transportation and the use of robots to disassemble the car. Honda plans to sell such secondary alloy as a metal hydride (MH), used as a hydrogen storage tank alloy. A executive of Japan Steelworks said that in recent years, Japan's metal hydride alloy needs to rise.

The company has produced such an alloys and the hydrogen storage tanks for more than 30 years. The hydrogen storage tanks of Japanese steel consists of metal hydride alloy, and such alloys consist of 60% nickel, 30% lanthanum and ruthenium and 10% silicone resin. The nickel alloy expands in contact with hydrogen, and the addition of the resin can control expansion.

According to Japan, it is said to produce a reservoir having a diameter of 4,200 mm and a height of 550 mm to use 4 tons of this alloy.
