9. In anhydrous environments, graphene hydrogen fuel cell membranes can improve battery efficiency Researchers from the Swanson School of Engineering at the University of Pittsburgh have found that graphene (a two-dimensional polymer of carbon dioxide and hydrogen) has an un...

6. Controllable electrons in graphene provide new opportunities for developing potential electronic devices Scientists have created tunable artificial atoms in graphene for the first time. The research results indicate that the technology used to control graphene electrons i...

Graphene is a thin carbon layer that can be applied in optoelectronics. Researchers are working hard to develop graphene photodetectors, which are crucial for many technologies. However, typical photodetectors made of graphene can only sense light in a small area, which limits their performanc...

In the long run, a research team has pointed out that the basic idea of adjusting pore size to filter specific ions can be applied to different thin films and has different uses. 2. Graphene coatings that can change color during deformation or fracture can detect cracks...

Due to the discovery of graphene, researchers were awarded the Nobel Prize in Physics in 2010. When can we see products produced by the world's most innovative materials? This article may help to dispel the fog for everyone. 1. Salt can be separated from seawater using g...

The smaller the internal resistance of all batteries, the better. The smaller the internal resistance, the stronger the high current discharge ability, and the more fully the electrical energy is released. Any power supply has a certain degree of internal resistance, and in...

Due to the unimaginable conductivity of graphene, the concept of graphene batteries has become a life-saving straw for breaking through the current bottleneck of battery technology. Especially in the domestic electric vehicle industry, any technological breakthroughs are linked to graphene bat...

4. Improper cycling Long term low-speed driving, short driving distance, or frequent electric starts; Or if it is used for too long at night and the front headlights are turned on, it is easy to cause insufficient charging and battery loss. If there is a p...

Loss of power is a phenomenon that occurs when the battery is low in charge and the voltage is too low, causing excessive discharge and damaging the coating of the battery plate. The working voltage of any car mounted electrical appliance has a standard range, beyond which the appliance is pro...

Due to the small current, using this method to measure will not cause significant damage to the battery itself. The measurement accuracy of the AC voltage drop measurement method is not as good as that of the DC discharge internal resistance measurement method....
