One text unveiled how Tesla layout battery recycling

Recently, Tesla's CTO Sterhu Ber has set up a new company called Redwoodmaterials, the main battery recycling. Unlike previous participation in other projects, this time, the role in this project is not investment, but executives and directors. Strikebel's complex role Sterhubel is different from Teslari's executives that are often hopped in Teslary.

He is one of Tesla's joint founders. As early as 2003, Masque began funding Strabur to study the lithium-ion battery pack, and then brought him into Tesla. Since so many years of speaking with Mask, Sterhubel is a number of people who can stick to the strict requirements and hot temper, now he is the most important figure after Tesce.

The sec file shows that another directors of Redwoodmaterials are Andrewstevenson, and he also serves as a CFO of RM. According to LINKEDIN, Andrewstevenson has entered Tesla after graduating from Stanford MBA in 2015, and is responsible for a special project that is unapprounded in the CTO office. From the current public information, Sterhu Ber and Andrewstevenson have not left from Tesla.

It can be speculated that Andrewstevenson should be reported to Strabel in Tesla, this special project without public names may be related to RedwoodMaterials. Redwoodmaterials received 2 million US dollars in April 17. According to the depth of participation in this, this investment is likely to come from Tesla.

But if you want to do battery recycling, Tesla does not do itself, but to set up a new company alone in the hands-on executives, is this new company may be Tesla's all-sized subsidiary? Serious support for raw materials to recover, let's first see how many ways in battery recovery. One is the secondary use of the second-hand battery, which is to achieve the design life, but the secondary use of batteries that have not been scrapped, such as using it in the energy storage market, light power or low-speed car market, standby power market, etc. Wait.

One is the recycling of raw materials, which is disassembled and recycled for the scrapped power lithium ion battery. There is also a kind of battery recovery, such as the main plant will recycle the whole vehicle, and dismantle the battery pack to test performance, used for technology research and development optimization. Strikebell firmly supports the second method.

He mentioned in the National Company Zhou, who participated in Mexico last year that in their repeated research on the life cycle of the battery life, the secondary use of the battery neither has no economic benefits, and there is no good use value. Typically, the minimum service life of the battery is 10-15 years. After the battery life is over, the technology applied on these batteries is very old, and the capacity and efficiency of the battery will fall, and the nonlinear decline trend, want to achieve more High reliability and predictability will be very difficult.

In addition, there will be a higher cycle life, and the price of new batteries is constantly decreasing. Sterlabell proposed that Tesla will recover battery raw materials as much as possible in the super factory. It can be seen from this public presentation that Tesla itself is a planning of battery recycling, and there is also a clear business direction, and the super factory integrates the supply chain practice, and it is also very suitable for battery dismantling, raw material recovery, and re-use process.

That is, Tesla is not from the battery, and there seems to be more cooperation from third-party companies. Back to Redwoodmaterials, only two sentences from this project official website, let's find a little clue. This project is positioned in the recovery, re-manufacturing and secondary use of raw materials, which is the path to the most respected battery recycling of Strabel.

Since this project exists independently of Tesla brand, it is not full supplement of Tesla business. The meaning of this project will be able to get from Tesla brand, facing the whole industry. That is, there is still developmental space in the industry's battery recovery body.

The battery recycling industry still needs to grow here, you can talk about domestic. Since the market recovered in the power lithium-ion battery has not entered the rapid rising period, the recycling company is generally small, and some companies that have no recycling qualifications are illegally engaged in waste battery recycling. Policy, of course, is going forward.

In December 2016, the Ministry of Environmental Protection revised the "Waste Battery Pollution Prevention and Treatment Technology Policy", and proposed "Encourage battery production company to perform producers to extend the responsibility", identifying a part of the car to undertake a part of the responsibility of the recycling. At the time of recycling of the battery, due to the logistics cost constraint, many participation must be truly reduced by recycling costs. Therefore, policy clearly put forward the responsibility of participating in the recycling of the society, encouraging battery production companies, waste battery collection companies and utilization companies and other joint construction waste.

Battery collection system. However, under the conditions that the technical specifications have not yet been perfect, the recycling system has not established, the series of policies related to the "technical policy" is mostly into encouragement policies, no mandatory management, the company does not have sufficient enthusiasm, with power lithium-ion battery production company Or electric car company has not yet appeared for the recycling system of the main body. Another regulatory policy is caused by the company.

In November 2016, the Ministry of Industry and Information Technology announced the "Notice of the Ministry of Industry and Information Technology to further do new energy vehicles", emphasized that "all new energy vehicles on the new production from January 1, 2017 Inboard terminal, through the company's monitoring platform to operate safety status of key systems such as vehicle and dynamic lithium-ion batteries, in accordance with the requirements of "Technical Specifications of Electric Vehicles Remote Service and Management System" (GB / T32960) National Standard Requirements Field vehicle related safety status information upload to local monitoring platform. "This regulatory policy can be cheated, monitoring the safety status of vehicle batteries, and also is closely related to battery recycling. The manufacturer records the encoding of each battery and the charge and discharge data used by each battery, even private privacy data.

By collecting the acquisition of these data, the manufacturer can pre-analyze the failure, monitor the battery safety status, to understand the life and use of each battery when reclaiming the battery, thereby better adoption method. That is, under the technical advancement of the power lithium-ion battery, battery recovery technology is also updated. Moreover, the dynamic lithium-ion battery model is diverse, the battery module structure is different, the assembly process is also very different, the technology and cost requirements of battery dismantling are not low.

Battery recycling must be clear responsible subjects, traditional battery recycling companies also grow. Due to the different policies of countries, the battery recovery has logistics costs, and the battery recovery must be based on localization. In Germany and Japan, battery manufacturers are responsible for battery recovery.

In the United States, the government adopts the method of collecting ambient fee as a fund support, and the recycling company can sell the recycled raw materials to the battery production company. Tesla is a technological innovation-driven company, Sterhu Belle began to love batteries from the student era, and he repeatedly said that he loves the battery to exceed the car. Behind the motivation of RedwoodMaterials, I believe that there is not limited to environmental or business prospects, and there is a variable space in battery recovery technology.

In the early days of the sales of new energy vehicles, high-end players have entered the battery recycling area earlier.
