Shengyu Mining (600711) announced on the evening of May 7 that the wholly-owned subsidiary Sheng Sheng Shanghui intends to establish Congo (Golden) Shengyu Mining Co, Ltd.

After the scrapped lithium battery, if it is handled improperly, the lithium hexafluorofluoride, carbonate organic matter and heavy metals such as cobalt and copper will inevitably pose a potential pollution threat to the environment On the other hand, cobalt, lithium, copper and plastics in waste lithium batteries are valuable resources and have extremely high recycling value.

The heat dissipation design is accurate and avoids excessive temperature difference in the system This is due to the performance requirements of the lithium battery.

Lithium batteries are usually divided into two categories: Lithium metal battery: A lithium metal battery is generally a battery using manganese dioxide as a positive electrode material, metallic lithium or an alloy metal thereof as a negative electrode material, and a nonaqueous electrolyte solution Lithium-ion battery: A lithium-ion battery is generally a battery using a lithium alloy metal oxide as a positive electrode material, graphite as a negative electrode material, and a non-aqueous electrolyte.

Recently, during the 25th World Electric Vehicle Conference, Zhong Xinlei, Chairman of the Board of Directors of Zhongju Leitian Power Battery Co, Ltd.

We often drives, we also need to know the various parts of the car If the car can't catch fire, then checking the battery is the first thing to do.

Studies have shown that as the temperature drops, the working hours of electric vehicle batteries are also shortened This fall, battery charging stations are quietly rising on the streets of Zhucheng.

Usually there are marked above, if it is not clear, there is a multimeter to measure it, use DC voltage gear, such as the range above 20 volts, the red pen is connected to one side, the black pen is connected to one side, if the display is positive voltage, It means that the red pen corresponds to the positive pole, and the other end is the negative pole If the negative voltage is displayed, it is reversed.

If god created the world, Konstantin Novoselov, who won the 2010 Nobel Prize for his work on graphene, is now trying to create something different -- to go beyond graphene itself and design properties from atoms to products on demand to explore new opportunities presented by the two-dimensional materialDressed in a white shirt, blue jeans, casual shoes and a backpack, the star of graphene and a renowned professor at the university of Manchester in the United Kingdom made a low-key appearance at the third graphene summit held by the Shenzhen graduate school of Tsinghua university on April 14.
