In the electric car, the three-power system is center, and the battery is the center of the center, the battery acts as the power energy and the origin of the whole vehicle, serves as a very important role. The battery of this charter, the battery of electric car is selected with a lithium ion battery. This battery energy is moderate, and it is also a more old, and it is more advantageous.

However, the lithium-ion battery also has a very funeral defect, for example, poor security, simplicity of fire; more, the charging speed is slow, the fastest to take a few hours. Not only that, the internal impedance of the lithium-ion battery is high. Since the electrolyte of the lithium ion battery is an organic solvent, the electrical conductivity is much lower than the nickel-cadmium battery, the nickel-hydrogen battery is low, so the internal impedance of the lithium ion battery is about 11 times more than Nickel cadmium and nickel-hydrogen batteries.

If the diameter is 18mm, the impedance of a single battery of 50mm is about 90m. In addition, the lithium-ion battery operating voltage is changed. When the battery is discharged to 80% of the extra capacity, the voltage change of the nickel-cadmium battery is small (about 20%), and the voltage changes in the lithium ion battery are larger (about 40%).

For the battery powered by the battery, this is a severe defect, but since the lithium ion battery discharge voltage is changed, it is also simple to test the remainder of the battery accordingly. The graphene battery is a new energy battery that uses a fast and many shuttle motion between the lithium ion between the surface and the electrode. The graphene is no longer a new concept.

The experts of domestic and foreign experts have made T many years. Although there are some inspiring experimental phenomena and effects, it is only in the theoretical stage of the laboratory, and it is produced. Distinguishment.

Therefore, the graphene battery is still unable to satisfy the conditions of mass production, so it is temporarily unable to replace the lithium ion battery.
