The future of automobile is coming: the material revolution rewrites the industry map

Abstract: it is not difficult to see that in the tide of the times, the opportunities in front of China's automobile manufacturing industry are colorful but also step by step urgent. But in the future, if electric power is a solution to automotive energy, then lightweight is the theme of the times. In this direction, the new cutting-edge materials incubated by the research and Development Institute of the chemical industry will become the basis and inspiration source for the vigorous development of energy innovation, intelligent technology, design process and so on, and deduce infinite possibilities for the future of the automotive industry

TORLON reg; Pai, which started at 200 "wear-resistant grade, has no comparable performance in lubricating environment for 9 years. When it was, the plan for the adjustment and revitalization of the automotive industry" Issued, under the guidance of the government's firm new energy policy and considerable subsidies, China began to be swept by a general trend of car manufacturing. From concept to practice, the direction of structural adjustment is the high-end product structure and diversification of raw material structure. For nine years, China has been struggling with difficulties while panning for gold in the waves

after the carnival, the world will eventually operate in a regular way

2018 is called "China's new energy vehicle outbreak year" by the industry. In the middle of the year, the new energy vehicle market has ushered in two new policies. In June, the new policy of financial subsidies for new energy vehicles was officially implemented. Taking 300 kilometers as the line, the mileage standard of new energy vehicles was clearly divided for the first time to reduce and increase. In July, the national development and Reform Commission issued the draft for comments on the regulations on investment management in the automotive industry, proposing that new traditional fuel vehicle production enterprises will not be qualified, and strictly control existing enterprises to expand the production capacity of traditional fuel vehicles. At the same time, strengthen the investment management of new electric vehicle enterprises, such as lower power tensile testing machines, to prevent blind distribution and low-level repeated construction

this means that high-quality and integrated technological innovation will become the main driving force for the development of new energy vehicles, and the previous strategy of relying on increasing the number of batteries, simply reducing or changing parts to pursue a small increase in mileage will no longer work

everything grows with the wind. Obviously, even the range of 300 kilometers is far from that of traditional fuel vehicles. The pain point of new energy vehicle mileage has once again become the focus and driving force of the industry

break through the bottleneck of battery power

improve the mileage of new energy vehicles. How to increase battery power is a hard fortress that cannot be broken for a long time. From the first generation of nickel metal hydride batteries and lithium manganate batteries, the second generation of lithium iron phosphate batteries, to the third generation of ternary batteries, which are widely used at present, the battery life ability seems to have been unable to break through the natural ceiling of battery materials

some materials show that the energy density of lithium-ion batteries in the existing system is basically difficult to exceed 300wh/kg, which is difficult to meet the demand of power batteries in the future. In the national plan for the development of new energy vehicles, the energy density of single batteries will reach 350wh/kg in 2020 and 500wh/kg in 2030, which means that the endurance mileage of electric vehicles will be doubled

demand extends the possibility of change to the more original chemical industry

"at present, the energy density of lithium batteries for new energy vehicles is greatly affected by key anode and cathode materials," said Zhu Jun, vice president of the global automotive industry team of Evonik industrial group, a German special chemical enterprise. "The selection and breakthrough of anode and cathode materials is a more feasible solution to significantly increase the energy density at present."

Evonik's solution is to add nano-sized pure silicon powder to the new negative electrode material, which greatly improves the energy density of the negative electrode material. The theoretical energy density of pure silicon anode can reach 10 times that of graphite material, up to 4200mah/g. According to previous public information, Tesla has used silicon carbon anode as a new material for power battery in Model3 by adding 10% silicon-based material to artificial graphite, so that the battery capacity has reached at least 550mah/g. In addition, Evonik's nanostructured alumina used for coating the separator of lithium battery can effectively improve the safety performance of the battery due to its excellent heat resistance

more new material batteries are brewing in laboratories around the world. In May this year, following the Japanese government's investment of 1.6 billion yen to support the joint research and development of solid-state lithium-ion batteries by Japanese battery manufacturers and the three major automobile manufacturers of Honda, Nissan and Toyota, foreign established car companies such as BMW and Porsche have invested in the research and development of solid-state batteries. At the same time, a large number of auto parts suppliers such as continental group of Germany, TDK of Japan and Murata Manufacturing Institute have also invested here

the curtain of a new round of vehicle battery innovation has opened

lightweight is coming, and new materials account for nearly half of the contribution.

Henry Ford, the founder of Ford, once said that any excess weight is fatal to the car

if the pursuit of a breakthrough in battery energy density is still on the road, the lightweight design of vehicles that also helps to increase the range of new energy vehicles has been applied since the era of fuel power

according to data statistics, the weight of pure electric vehicle is reduced by 10kg, and its endurance mileage can be increased by 2.5km

with the increasingly urgent need to improve the endurance mileage, lightweight thinking has become the mainstream in the contemporary era. Chen Yilong, director of the lightweight technology innovation strategic alliance committee of the Chinese society of engineering, believes that new materials and technologies account for 41% of automotive lightweight

however, Chinese cars, which have been seeking to "overtake in corners" by taking advantage of new energy, still lag behind foreign advanced levels in lightweight technology. According to the 2017 data statistics, in terms of the current mainstream lightweight magnesium alloys, the average magnesium consumption of foreign passenger cars is about 5kg, while the magnesium consumption of Chinese self owned brand models is less than 1kg. According to the "road map of energy saving and new energy vehicle technology" released in 2016, the consumption of domestic magnesium alloy for single vehicle will reach 15kg in 2020 and 45kg in 2030

according to the data, at present, there are more than 60 parts of foreign cars using magnesium alloy, among which 7 parts, such as steering wheel frame, steering column support, instrument panel frame, seat frame, valve cover, gearbox housing, intake manifold, etc., have the highest utilization rate of magnesium alloy

but the materials that can promote the lightweight of cars are far more than magnesium alloys and other metals. The innovative choice of materials determines whose starting line is naturally ahead

Zhu Jun said that cars usually reduce energy consumption by improving the powertrain, reducing wheel resistance, lightweight and streamlined design, and the powertrain and body shape are closely related to lightweight. In the future, the lightweight design of all structures will be realized based on the imagination provided by materials

Evonik provides a complete set of metal alternatives. For example, rigid foam named Rohacell can be combined with carbon fiber skin to form a sandwich structure, which has the characteristics of light weight and high rigidity,. It is an ideal foam core material with composite sandwich structure for automobile structural parts and body covering parts such as compartment cover, door, roof, etc. The new Rohacell hero also has high impact resistance. In case of impact, it can buffer deformation and absorb energy, forming pits on the outer surface of the sandwich structure, so as to detect the internal fiber condition. This can not only effectively avoid the risk of undetectable impact damage, but also reduce noise and NVH (noise, vibration and acoustic vibration roughness)

in addition to the car body, Evonik is still exploring ways to use high-performance polymers to replace metal parts such as anchors, chains and gears in the car. Vestakeep, a polymer with high lubricity and wear resistance developed by it, has been used in underbody universal chains, transmission parts, supercharging systems, etc. VESTAMID polyamide 12, which has high stability and wear resistance, plays a better role in the gear transmission mechanism of steering angle sensor than metal parts in terms of chemical resistance, high temperature resistance, noise reduction and shock absorption

"if these new materials are used to optimize the glass and replaceable metal parts of the whole car, the weight of the car can be reduced by at least 40% in the future," Zhu Jun said

chips for future cars

behind the global automotive new energy transformation in full swing, there are unlimited expectations and demands for future smart cars and driverless cars

according to the definition of the U.S. Highway Administration (EPA), intelligent vehicles are divided into four levels. From the most basic auxiliary driving, cooperative driving based on car couplets, to driverless driving with limited conditions, and finally to driverless driving under all driving conditions, the direction of future automobile and human road traffic has been clear. In a larger timeline, the difficulty of endurance mileage is just a small node

in December 2017, the Ministry of industry and information technology released the three-year action plan for promoting the development of the new generation of artificial intelligence industry (year), pointing out that by 2020, it will establish a vehicle intelligent platform that supports the research and development of key technologies and products such as vehicle intelligent computing platform architecture, on-board intelligent chips, autonomous driving operating system, vehicle intelligent algorithms, and build an intelligent vehicle platform integrating software, hardware, and algorithms

this means that taking new energy as an opportunity and with the support of new materials, China hopes to realize the real overtaking of the automotive industry through automotive intelligence

in this sense, electric energy, electronic control system and light-weight car body will make the intelligent chip carried by the car play a great role in sensor interconnection, automatic driving, safety assurance, etc., all of which are the development trend of road traffic in the future

the development of new material industry will become the infrastructure supporting this trend. For example, in terms of communication interconnection, the Rohacell hard foam used by Evonik to build car bodies and the baokeli material, which is transparent, sunscreen and can replace automotive glass, have complete signal permeability compared with the metal and glass materials widely used at present; At present, the transparent nylon trogamid, which is mainly used in smart home, can be implanted with sensors, and the manufacturing of special functional components can be completed through 3D printing. The application of these new materials in the automotive industry will enable the existence of 5g signals in the future, which will serve the real intelligent urban transportation, and the automobile will truly become a new entrance to the Internet in the era of all things connected

among the possibilities brought by more metamaterials, researchers believe that it can also be used for oil and natural gas control, seawater desalination, wastewater treatment and other future intelligent vehicles, which can jump out of the current relatively monotonous metal four-wheel objects and project a clearer blueprint. From the perspective of Evonik Rohacell's in mold foaming technology, it is possible to get rid of stamping and welding processes to achieve overall manufacturing in the future, which means that any streamlined car body more suitable for reducing energy consumption can be built or even mass produced

in the future, the river will be magnificent, just at the time when hundreds of boats compete for water. On July 10, Tesla, the founder of new energy technology, settled in Lingang, Shanghai, and built the first Tesla overseas super factory integrating R & D, manufacturing, sales and other functions. The project plans to produce 500000 pure electric vehicles per year

it is not difficult to see that in the tide of the times, the opportunities in front of China's automobile manufacturing industry are colorful but also urgent step by step. But in the future, if electric power is a solution to automotive energy, then lightweight is the theme of the times. In this direction, the new cutting-edge wood products incubated by the research and Development Institute of chemical industry will become the basis for the vigorous development of energy innovation, intelligent technology, design process, etc
