We know about graphene chemistry: similar to the surface of the graphite and graphene can adsorption and stripping of all kinds of atoms and molecules From the point of view of surface chemistry, graphene is similar to the properties of graphite, graphite available to estimate the properties of graphene.

In June, Shandong Dongyue announced conquer used to make fuel battery core material sulfonic acid resin ionic membrane technology, the annual output of 500 tons of production device has been completed and put into operation Solved the hydrogen fuel cell production major bottlenecks, China become the world's second country with the industrialization of the technology and ability.

With the development of modern electronic technology, electronic equipment is increasingly tend to be more portable, more functional, and thus the power supply to them battery light weight and efficient requirements are put forward Lithium ion batteries with its high energy density, charge and discharge performance is excellent, non-polluting characteristics gradually replace the traditional nickel cadmium, nickel metal hydride batteries, lead-acid batteries are widely used in modern portable electronic products.

The unit of capacity of the battery is AH (Ah), which is the product of current and time The battery of 100AH capacity can be discharged after being fully charged and discharged at a current of 100A for one hour, 50A current for two hours, 20A for five hours! Of course, this is a theoretical value, and it is actually impossible to discharge at a constant current.

In China, as one of the core components for the development of electric vehicles, power batteries have always been a hot spot in the field of battery research In the key national special research and development plan for new energy vehicles launched in 2016, Hong Li, researcher of the Clean Energy Laboratory of the Institute of Physics, Chinese Academy of Sciences, is responsible for the “Long-term Power Lithium Battery New Materials and New System Research” project, aiming to develop high energy, high density, high-safety lithium battery to improve the cruising range of electric vehicles, the project proposed to study lithium-ion batteries, semi-solid lithium-sulfur batteries, solid-state lithium-air batteries, three long battery lithium batteries will become the future of China's new energy vehicles core.

Recently, as a priority of the “13th Five-Year Plan for National Major Science and Technology Infrastructure Construction”, the hardest X-ray Free Electron Laser Device (XFEL), the largest investment in science and technology infrastructure in China, has been approved This kind of device is called "high-speed camera" by scientists called "Nature" magazine because it can help scientists to see the microscopic world on the atomic scale and even on the electronic scale.

Although domestic subsidies for new energy vehicles have begun to decline, the gradual enrichment of infrastructure and the growing number of optional models have also allowed consumers to embrace the popularity of new energy vehicles In addition to being an alternative solution to the purchase of fuel vehicles as a restricted area, new energy vehicles also have many unique advantages.

According to the data compiled by the Research Department of the Power Battery Application Branch, the installed capacity of new energy vehicles in April was 3,70995Mwh, an increase of 301.

First of all, on the road of “to zero emissions”, electric drive is the only way Power batteries with excellent performance depend on the core technology of battery systems and battery manufacturing technology.

As the domestic automobile culture is still not mature enough, many people's car concept still stays in the car is "expensive", need to be careful "care" state, thus creating a lot of incorrect car concept, such as "high speed harms the machine ", "up shift to save fuel", "slow speed to save fuel" and so on In this kind of environment, there are more and more "tonics" in the market, especially the variety of oil additives, and there are countless people! Today, let's talk about what the oil additive is.
