Overview：If you have an electric car, you will find that most of the batteries are lithium batteries. However, due to the poor safety and fire risk of lithium batteries, graphene batteries have become a hot research direction in recent years. So will graphene replace lithium batteries for electric vehicles in the future?

Indeed, with the trend of globalization of sustainable new energy sources, national policies are now strongly supporting the development of electric vehicles/vehicles. As the power source of electric vehicle, the core significance of battery is very important. Therefore, if graphene technology can break through, it is also of great significance.
Graphene is the thinnest, hardest and least resistive nanomaterial in the world. The so-called graphene battery is a kind of new energy battery developed by utilizing the characteristics of lithium ion moving rapidly and extensively between graphene surface and electrode. Therefore, graphene batteries have many advantages.
Firstly, as a magic material of new black technology, if graphene batteries can provide power for new energy vehicles, they will have great development prospects in the future. Compared with lithium-ion batteries, graphene batteries are ultra-light, charge faster and cost more than 70% of lithium-ion batteries.
So earlier, the concept of graphene battery has been heated in the field of new energy vehicles, and after years of research and development at home and abroad, it seems that the concept has gradually changed into reality, and many experimental phenomena and results are highly expected.
If there are reports that battery manufacturers are already developing melene battery technology, and the products will meet with you around 2020, it is worth looking forward to.
Compared with black technology graphene technology, lithium batteries, as the mainstream battery type in the new energy vehicle market, are favored by global new energy vehicle manufacturers such as Tesla because of their relatively high energy density and mature cost advantages.
Of course, nothing is absolute, and lithium batteries also have their weaknesses. Compared with nickel-cadmium batteries and nickel-metal hydride batteries, the internal impedance of lithium batteries is about 11 times higher, and the conductivity of lithium batteries is much lower than that of nickel-cadmium batteries.
In addition, compared with nickel-cadmium batteries, lithium batteries have a greater change in operating voltage. That is, when the battery discharge reaches 80% of the rated capacity, the voltage of lithium-ion battery varies by about 40%, which is quite disadvantageous for the power supply battery.
It seems that lithium-ion batteries have many weaknesses. Compared with nickel-cadmium batteries and nickel metal oxide batteries, lithium-ion batteries do not have much advantages, let alone graphene batteries. Nevertheless, lithium batteries are still the preferred power batteries for new energy electric vehicles.
