Graphene stands out as one of the great alternatives to lithium for the construction of batteries for electric vehicles. The problem is that its extraction is more expensive hence, at the moment, most of the projects are just projects and nothing else. This is not the case with the GAC Aion V, which already claims to be the first electric car with a graphene battery on the market.
Although lithium-ion batteries are the most widespread; there are many types of batteries that can be found on the market. Each one aims to be more efficient and capable than the previous one, being the number of loads it supports before beginning to show its degradation, the cost of use and the ease of recycling once its useful life is the main challenges for manufacturers.
The graphene batteries obtained very good results in all and each of the preceding paragraphs. Graphene is a material made of carbon in which the atoms form a honeycomb pattern. The resistance, flexibility, lightness and high conductive capacity are some of the characteristics that make it a suitable material for electric car batteries.
The result of using this material is energy storage with higher energy density and higher load capacity. So much so, that they can reduce waiting times for a charge to 80% down to eight minutes.
The problem is that with graphene not everything is advantageous. Its characteristics also include that it is a very expensive and complicated material to manufacture. This is the reason why, although many manufacturers see it as an option with a future to improve their electric models, very few have advanced projects.
In the first line is the GAC Aion V electric car. This Chinese electric SUV will be the first production model with a graphene battery to hit the market (the start of its production is scheduled for September).
At the moment, there is not much data that has transcended the new GAC. It is known that its graphene battery will allow it to travel up to 1,000 km with a charge. Also, that, connected to a 480 kW charger, it will recover up to 80% of its energy in less than 10 minutes (remember that, except for a few examples such as the Audi e-tron, the waiting time for a fast charge is usually around 30 minutes).
