Some people say that the probability of a pure electric vehicle burning in a serious collision is many times higher than that of a gasoline vehicle Some authorities have said that the risk of electric vehicle fire is not higher than that of a conventional gasoline vehicle.

Power batteries are the core of new energy vehicles With the increasing production of batteries and the large number of products on the market, a problem that cannot be ignored has been placed in front of us urgently, that is, the recycling of used lithium batteries.

When it comes to the lifeblood of new energy vehicles, it is the battery As the power source of electric vehicle, battery plays an important role.

Recently, Gree Group acquired ChangYuan Group with more than 5 billion Yuan to enter the field of new energy auto parts In the evening announcement issued by ChangYuan Group, Gree Group's acquisition amounted to approximately 265 million shares, accounting for 20% of the company's issued shares, and the offer price was 19.

Recently, the Ministry of Industry and Information Technology issued the "Lithium Battery Industry Standard Conditions" (draft for comments), covering industrial layout and project establishment, production scale and process technology, product quality, comprehensive utilization of resources and environmental protection, safety management, health and social responsibility, supervision and management In recent years, the development of new energy vehicles has received widespread attention.

One useful feature of lithium-ion batteries is that, when they are discharged, the voltage of the battery decreases with the passage of the charge and has a fairly steep slope This gives us another approximate metering method.

From mobile phones, 3C products to electric vehicles or large-scale energy storage power plants, lithium-ion batteries can be said to be ubiquitous, mainstream energy storage technology today, but the safety nature has always been criticized, so many scientists have tried to find various solutions According to the Journal of the American Chemical Society, NanoLetters, scientists have found that nanowires not only reduce the flammability of lithium ion batteries, but also enhance battery performance.

Since physicists AndreGeim and KonstantinNovoselov of the university of Manchester, United Kingdom, Shared the 2010 Nobel Prize in physics for their "groundbreaking experiments with two-dimensional graphene materials," any news or research on graphene has received a lot of attention So what are the potential advantages of graphene lithium battery recharging? For example, the popular lithium battery with mobile charge makes the audience full of expectation for the application of this technology.

The new energy vehicle and related power battery industries are expanding rapidly In the first half of this year, China's new energy vehicle sales rose 127 percent year-on-year to 170,000 units.

On June 7, the State Administration of Market Supervision and Administration and the State Standardization Administration issued the "National Standard Notice of the People's Republic of China(No 9 of 2018)" and approved the issuance of 393 national standards such as "Industrial Boric Acid" and 7 national standards.
