Brief introduction of BYD's battery material layout

Only 20 days after the update of the prospectus, this Friday, the website of the China Securities Regulatory Commission announced that the Ningde era will be listed on April 4. Not surprisingly, the unicorn in the power battery field is about to enter the capital market.

Only one day later, Xi Shen deputy general manager of BYD's lithium battery division, said at the 2018 Pearl River Delta Future Automotive Supply Chain Innovation Forum that the business divestiture of BYD's power battery is accelerating. It is expected that the split will be completed by the end of 2018 or early 2019. From 2022 to 2023, BYD's power battery company will also be listed separately.

“Adjusting the posture” is the core theme of Xi Shen’s public speech. It is also the general direction of BYD’s strategic adjustment since the beginning of 2018. Whether in the supply chain, technology or market, BYD is breaking the previous closed mode, more active embrace the outside world.

On March 21, BYD Chairman Chuanfu Wang visited Baoding and Jianjun Wei personally received it. It is speculated that one of the main purposes of Chuanfu Wang’s visit is to sell power batteries to Great Wall Motor.

This kind of guess is based on the consideration that, on the one hand, due to the lack of Great Wall points, the new energy vehicle product line is still insufficient, so new energy vehicles are urgently needed to fill the gap, but new energy vehicles need a large number of power battery packs, and major manufacturers are already full of orders, and Great Wall has signed a contract with BMW MINI new energy, also faces the choice of power battery supplier.

On the other hand, in mid-2017, the power battery module was supplied to the entire new energy vehicle market. This change was seen as the beginning of BYD's breaking of the original vertically integrated operation mode. From the perspective of BYD's publicly available capacity information, it has the ability to supply capacity externally.

The opening of the power battery is only the beginning of BYD's embrace of the outside world. The high-tech lithium battery has learned that the cooperation between other parts and the outside world is also progressing.

On March 28th, the theme technology exchange meeting of Beiqi New Energy-BYD Auto Parts Exhibition was held in Beijing. At the exchange meeting, the two teams conducted in-depth exchanges on the core technologies and key components of power batteries, motor electronic control, power train, automotive electronics, components, body accessories, and new energy vehicle chassis.

Gaogong Lithium was informed that including the senior vice president of Beiqi New Energy, Chen Shanghua, Franco Bellillo, Luo Zhongliang, general manager of BYD Automotive Electronics, and Pan Shiyi, deputy general manager of Powertrain Division, attended the exchange.

Such a high-profile docking has never been before, so this is the actual move of BYD's open strategy.

According to informed sources, in February of this year, Chairman of the BAIC Group Xu Heyi personally led a team to visit BYD, reached a high consensus on the direction of cooperation, and actively promoted the exchange.

GGII analysis pointed out that although the possibility of supporting in the field of power battery is not large, in other three power products, smart car electronics, etc., BYD and Beiqi New Energy are very likely to cooperate in depth.

In addition, an insider of BYD also revealed that BYD may open a global car developer conference this year to further implement the open platform strategy.

"From vertical innovation to such a large degree of openness, BYD must take the initiative to open up, which is already a consensus within BYD," said the insider.

Despite the lateness of the time node, BYD’s strategic adjustment has accurately stepped on the trend of the industry. From an international perspective, whether it is a cooperative alliance established by Japanese Honda and other Japanese car companies, or BMW Daimler The merger of travel business, through the deep cooperation of car companies has indeed become a realistic path to enhance the competitive strength in the context of electrification.

However, it is worth noting that compared with the cooperation of international car companies, the cooperation between BYD and Great Wall and BAIC is only at the supply chain level. In the future, further deepening cooperation between domestic car companies and car companies should be extended to a deeper dimension. .

Look at the major events in the lithium battery industry this week.

1, battery company Q1 is better than the same period last year

A number of high-power battery companies said to the high-tech lithium battery that the company's power battery orders growth in the first quarter of 2018 is better than the same period last year. Even battery companies have been in full production since the fourth quarter of last year, and the products are in short supply. At the same time, there are also a number of power battery listed companies that indicated that customers have placed orders in the first quarter, which is obviously better than the same period last year.

High-tech lithium battery notes that from January to March 2018, Guoxuan Gaoke and Jianghuai, Beiqi New Energy and Dayun Auto, Waterma and Hubei Xinchufeng, Oriental Seiko and Beiqi New Energy and other power batteries and OEMs, A total of 78,000 sets of power battery system purchase contracts were signed, and it is expected that other power battery purchase orders will be rolled out later.

According to industry insiders, the overall situation of the power battery industry in the first quarter of this year is better than that of the same period of last year. The main reason is that the large-scale growth of new energy vehicle market in the first quarter led to the growth in demand for power batteries. The OEM hopes to clear the inventory before the end of the transition period of the subsidy policy in 2018, and sell the batteries for the best-selling models last year to get as much subsidies as possible.

The data shows that the production and sales of new energy passenger cars, new energy passenger cars and new energy special vehicles in January-February 2018 have increased to varying degrees compared with last year. Among them, new energy passenger cars are still the main force of market growth, and A00-class mini-cars account for the largest proportion of sales, which has become the main force of current power battery rush.

2, 2018 or become the first year of NCM811 mass production

The data shows that the market mature 18650 power battery uses 532 cathode materials, the battery capacity is 2.5AH, and the 811 cathode material capacity can reach 2.75AH. The cost of using 811 units of WH cathode material is 0.39 Yuan, while the cost of using 532 unit cost WH cathode material costs 0.414 Yuan and the cost is reduced by 6%.

On the whole, the weight of the cathode material using 811 single cells decreased by 9%, and the cost of the corresponding separator, electrolyte, and copper foil was also reduced. Based on the conservative principle, after the 810 is adopted, the unit cost of the unit is reduced by 7%. After considering the PACK, the cost of the integrated unit WH is about 8%.

It is worth mentioning that the large-scale application of 811 is also a big plus for cathode materials companies. At present, the price of 532 is 230,000 Yuan, and the price of 811 is 260,000 Yuan. The current market situation, assuming 532 processing cost is 0.5 million Yuan / ton, 811 processing cost is 10,000Yuan / ton, then the gross profit margin of 532 is 15 %, while the gross profit margin of 811 can reach 27%, nearly doubled.

Obviously, the large-scale application of NCM811 is a win-win situation for car companies, power battery companies and cathode materials companies. Combined with market demand, it is expected that 2018 will be the first year of mass production of NCM811.

3. Price reduction space for four key materials of power battery

"Reducing cost" is one of the most important issues faced by power batteries this year. There are many ways to reduce costs, involving various links. It is an important way to negotiate with material suppliers and switch to materials with lower costs.

At present, the four key materials of anode, cathode, diaphragm and electrolyte account for about 40%, 20%, 8% and 10% of the cost of power battery respectively, accounting for nearly 80% of the cost. The ability to reduce the cost of these four key materials is of great significance for power batteries.

The high-tech lithium battery has analyzed and judged the falling space of the four key materials in 2018 from the supply, technology and market demand.

4, the card position technology life door 6 major international car enterprise power battery layout

As the core component of new energy vehicles, the current power battery still accounts for 40%-50% of the total vehicle cost, which is very important for the overall cost, performance quality and even stable production of the whole vehicle (refer to Modle3). Therefore, for any international mainstream car that is interested in making a difference in the new energy vehicle market, the power battery must be firmly in its own hands.

It is not difficult to find out the corresponding layout. The current international car enterprise layout power battery has two major characteristics:

First, the layout is concentrated on the technical level, and it is urgent to enhance the initiative. More car companies choose to use the funds to establish R&D centers and strengthen joint research and development of batteries, such as BMW's R&D center, and GM/Honda and BMW/Toyota to jointly develop fuel cells. In fact, in addition to Tesla, it is rare to actually invest huge sums of money to build a power battery factory;

Second, the technical reserve is showing a diversified trend, with a focus on lithium batteries, fuel cells and solid-state batteries. BMW is a typical example of this. Over the past 20 years, BMW has conducted extensive experiments on fuel cells, as well as almost all types of secondary batteries including lead acid, Na-S, ZEBRA, nickel hydride and lithium ions, but The new energy vehicles that are finally being prepared for launch are still dominated by electric vehicles and fuel vehicles.

According to the analysis of the High-tech Research Institute of Lithium-Ion Research Institute (GGII), with the deepening of the layout of power batteries by international car companies, the current situation of “China, Japan and Korea” in the industry may also change.

5. From the performance of six lithium-ion film companies, where is the 2018 bonus?

The decline in diaphragm prices has become irreversible, but it must be recognized that the dividends in the key materials of the four lithium batteries should not be underestimated.

High-tech lithium battery inventory Shanghai Enjie, Xingyuan material, Shengli Precision (Suzhou Jieli), Zhangzhou Mingzhu, Yuntianhua (Numi Technology), Sinoma Technology 6 listed companies lithium battery performance found, in the past price of gross profit both diving In 2017, many diaphragm companies sat on the Diaoyutai and enjoyed the market dividend.

Fundamentally, a common reason for the growth of these diaphragm companies is that the subsidy policy has declined in 2017, and the energy density is directly linked. The demand for ternary power batteries has surged, and even many mainstream lithium iron phosphate battery companies have announced the layout.

It can be expected that in 2018, the ternary power battery will still be the mainstream demand of the new energy vehicle market. This is undoubtedly a good news for the diaphragm companies. However, according to the performance of the above six diaphragm companies in 2017, not every company can share a cup.

6, the supply chain tour survey South China war

As one of the most influential brand activities in the industry, the research tour of the supply chain of high industry lithium battery has reached the seventh session. This year, the tour takes south China station as the starting point, and it is expected to take two months to cover more than 30 cities in 4 regions and visit more than 50 mainstream power battery enterprises in China. Measure industrial development with footsteps and feel the pulse of the industry through field visits.

This week, the research team visited Zhenhua, Chuangming, Zhuoneng, Tuobang New Energy, Zhuhai Guangyu and other South China lithium battery companies.
