Lithium Grid News: "In 2017, 99.9% of the logistics vehicles we sold were electric. Last year, the sales of electric logistics vehicles exceeded 2,000, which was five times that of the previous year." At the exhibition, Nanjing Iveco told reporters. 
At the Iveco booth, three electric logistics vehicles are lined up. At present, Iveco's electric logistics vehicles have formed partnerships with major customers such as SF Express and Jingdong, and are running in first- and second-tier cities in China. This year the company's goal is to sprint the task of selling 5,000 electric logistics vehicles.

Nanqi Special Vehicle Co., Ltd. has brought pure electric closed barrel garbage truck products. According to company sources, such new energy special vehicles increased sales by 200% last year. The general sanitation car runs 100 kilometers a day, and the electric sanitation car can run 200 kilometers on a single charge. 
The person in charge of the China Electric Vehicle Industry Association said that the replacement of traditional fuel vehicles by new energy vehicles is becoming the mainstream of the times. Internationally, from 2015 to 2016, European countries have announced the ban on fuel vehicles. Fiat Chrysler, Mercedes-Benz, BMW, Lincoln, Jaguar Land Rover and other auto brand giants have announced that they will stop production of fuel vehicles. In addition, China's domestic vehicles such as Beiqi and Changan also announced in the second half of 2017 that they will completely stop production and sales of traditional fuel vehicles in 2020-2025. Geely Volvo announced that it will stop selling fuel vehicles in 2019. 
Data show that in 2017, China's auto market sales were 28.879 million units, an increase of 3%. Among them, new energy vehicles sold 777,000 units, a year-on-year increase of 53%. In 2017, sales of new energy passenger vehicles in non-restricted areas increased, and the proportion has increased from 41% in 2015 to 56% in 2017. 
The road to manufacturing: short-term electric vehicles, graphene to supplement 
new energy vehicles, although the growth rate is faster, but many bottlenecks have not completely broken through. For example, lithium batteries have much lower energy density than gasoline, and can only carry a battery heavier than gasoline in order to obtain a higher cruising range. How to reduce the burden on new energy vehicles?A magical lithium-ion material called "graphene" enters the sights of manufacturing companies. 
The car company Briggs has released a car made of graphene in the British National Graphene Research Institute, called BACMono. This is the world's first car made of graphene. Because of the use of graphene material, the weight of the car body is reduced by 20%, and the strength is 200 times that of ordinary steel.
Graphanano of Spain and the University of Corvado of Spain have cooperated in the development of graphene batteries. The laboratory data proves that the battery power is about 5 times that of lithium batteries. It takes only 8 minutes for one charging time and 1000 kilometers for driving. The service life is currently lithium. The battery is twice as large. The Chaowei Group, which has been actively developing graphene batteries, briefly summarized yesterday: “Graphene is to make the battery run farther and last longer, and the battery in winter is more powerful!” 
“Graphene can be used not only for new energy vehicle batteries, It can also be used in many places in the car." At the exhibition, the people of Xianfeng Nano Company added to the reporter. For example, for automotive circuits, electrons move less in graphene and consume less energy than silicon. When used in automotive anti-corrosion coatings, it is sprayed on the steel surface with graphene. The body is immersed in seawater for one month without rust, while ordinary high performance coatings can only last for several days. The electric heating seat is one of the necessary devices for luxury cars. By adding graphene as a reinforcing material to polystyrene, a composite material with high strength, good electrical and thermal conductivity and light weight can be obtained. 
Waiting for the wind, the car companies wait for the price of graphene to "divide" 
Although graphene is known as the next vent of new energy vehicle upgrades, but the reporter found that there are few automotive graphene materials at the show. Iveco and other manufacturers frankly because of "expensive." 
Wang Xu, chief engineer of Beijing Beiqi Deben Automotive Technology Center, said: “Graphene is currently in a silent period, but I think this is the same as when carbon fiber just entered the manufacturing industry. The carbon fiber material was quiet for several years because of cost and other reasons. However, the outbreak will eventually erupt." The 
industry believes that through technological improvements, graphene prices will eventually fall to an acceptable range. From the trend, the price of graphene has reached 5,000 yuan / gram when it was first introduced. Now the price of graphene powder has dropped to 300 yuan, and there is still a lot of room for price reduction. 
In addition, Wang Xu said that it takes time for graphene to go from the vehicle factory lab to the market, which is determined by the characteristics of automobile development. “Many auto companies are already doing graphene material testing, but a new car usually has a development cycle of 36 months. Even if you only use graphene materials to improve the car chassis, it’s only two or three years for the handling experiment. wait."
