Car companies accelerate breakthroughs in new energy vehicle layout battery technology


With the clear and detailed step-by-step view of national and local new energy policies, and the opening up of new energy automobile policies in cities such as Beijing and Shanghai, a number of new energy vehicles have also been intensively released this year and have really entered the market, regardless of imported vehicles or joint ventures. The car is still an independent brand, and more and more new energy models are available to consumers.

Today, new energy vehicles that have appeared on the Chinese market, including those already on the market or will be listed, are mainly electric vehicles, such as BYD e6, JAC iEV4, BAIC E150, SAIC Roewe E50, Kai Chen Morrowind, Teng Shi, BMW. Zino, BMW i3 and i8, and Tesla et al. In addition, there are also some plug-in hybrid vehicles, such as BYD Qin, Volvo S60L plug-in hybrid. Of course, there are still more car companies planning to launch more new energy products for the Chinese market in the future.

Accelerate the strategic layout

No car company will be willing to post. Riding on the policy of new energy vehicles, various car companies are seizing market development opportunities and occupying more favorable competitive seats.

Recently, Volkswagen launched a week-long electric vehicle promotion campaign in the Chinese market. During the media briefing, Volkswagen China President Jorge Heitzman said: "In the near future, Volkswagen will supply more than 20 new energy vehicles to Chinese owners, from small cars to large SUVs, from plug-in hybrid vehicles. To pure electric.” As early as April of this year, Volkswagen signed agreements with its partners in China, FAW Group and SAIC Group, to jointly develop environmentally friendly vehicles and new energy vehicles for the Chinese market, including fuel cells and plugs with SAIC. In cooperation with the electric hybrid technology, it will jointly develop and produce a new car with outstanding environmental performance with FAW Group.

In March of this year, Beijing New Energy Automobile Co., Ltd. was established and became the first joint-stock new energy automobile company in China. As a new development platform for the new energy automotive industry, this company has a registered capital of RMB 2 billion and will create an integrated model of research, manufacturing, and sales industry chain, which will fully support Beiqi Group's new breakthrough in the industrialization and marketization of new energy vehicles. . This year, BAIC New Energy plans to sell 20,000 pure electric vehicles and build a dedicated new energy sales channel.

Since Qin has been in short supply, power batteries have become the main bottleneck restricting sales growth of BYD's new energy vehicles. BYD has built a new battery factory this year, with an annual production capacity of 6GWH. Its first-phase plant has been put into production in September. In addition, BYD recently signed a strategic cooperation framework agreement with the Hebei Provincial Government, stipulating that it will build a BYD Chengde new energy automobile and parts production base project and build Chengde as an important R&D and production base for new energy vehicles. It is understood that BYD Chengde New Energy Automobile and its parts and components production base plans to invest a total of 2 billion yuan. After the project is completed, it is expected to produce an annual output of 5000 pure electric buses. In the process of project construction, BYD Co., Ltd. will gradually build production lines for related parts and components such as motors, electronic control and power batteries in Chengde City, continuously increase the proportion of local support, and gradually form the largest R&D and production base for new energy vehicles in the north.

Battery technology breakthrough

At the same time as policies continue to be introduced, the industry itself continues to make efforts in technical patents. According to Ouyang Minggao, a professor at Tsinghua University, the specific energy of the battery system in our country is about 100 watts per kilogram and is expected to reach 200 watt-hours per kilogram next year, and is expected to achieve 300 watt-hours per kilogram by 2020. It is also known that as one of the key inner layer components in battery technology, lithium battery separator technology has made important progress and will effectively improve the safety performance of the power battery.

In the domestic power battery field, the lithium iron phosphate-based situation will soon be broken. It is understood that the end of this year, Beiqi second-generation E150EV will be equipped with ternary lithium battery system, the battery has more advantages in the endurance and price. JAC's fifth-generation electric vehicles, which are expected to be available at the end of this year, will also use ternary lithium-ion batteries, which require 23 degrees at a full charge and a cruising range of 200 kilometers, an increase of 40 kilometers.



Gold-loaded Carbon Desorption

Above-mentioned equipment was successfully developed by Changchun Gold Research Institute in 1998. It has possessed three patents and five monopolized technologies. Desorption solution does not contain sodium cyanide, it can reduce the grade of barren carbon down to 100g/t. The key technology of this equipment is that it can ensure the balance of metal quantity, and avoids gold- accumulating and gold- floating from the equipment, ensures the technological index steady and low cost of it. The content about technological advantages has been broadcasted by Xing Huo Science and Technology of CCTV. This technology was appointed as the energy-saving technology of gold production by National Development and Reform Committee in 2006, and was also appointed as standard equipment in the industry by National Development and Reform Committee in 2007, it passed the technique identifying in 2003, and won the second award of science and technology of China National gold Association, the entire technical level is advanced at home. This equipment has won three patent rights of China. The patent numbers of it are separately: 01241537.5 01241538.5 200620029209.1
