The dream of an electric refueling at the same level as a gasoline one is closer. The first car with a graphene battery could begin mass production in September.
The graphene is the great promise yet to come. We have been talking for years about its revolutionary properties, which are many, but its practical applications are still very scarce. The reason is that although graphene is a cheap and abundant material, since it comes from carbon, which is abundant in Nature, it is still expensive and difficult to manufacture on an industrial level.
Experts estimate that the first graphene batteries, at an industrial level, they will arrive in 2025. But the Chinese electric car manufacturer GAC assures that it has developed an industrial scale graphene battery manufacturing system, and at an affordable price, it will be ready this September.
The first car to use them is the new one GAC Aion V, and the data is revolutionary: 1,000 km of autonomy, and recharges the battery to 80% in 8 minutes. Like a fuel car …
Why can this material revolutionize car batteries?
The graphene It is made up of a sheet of pure carbon one atom thick, in which the atoms form panels of bees. It is a million times thinner than a sheet of paper. It comes from graphite, which is a very abundant material in nature.
It is light but very strong, superconducting, conducts heat, repairs itself, generates electricity when it receives light, and changes its properties when combined with other materials, among many other properties.
Applied to car batteries, as our colleague Elena Sanz tells us in Auto Bild, graphene makes it possible to manufacture batteries with a high energy density. It also supports fast high energy charges without these interfering in its useful life.
In the case of GAC Aion V, The graphene battery can withstand a recharge with a power of up to 480 kW.
His fast charge enter the category 6C, the highest that exists in this context. The higher the number that accompanies the letter C, the more efficient the fast charge.
This allows the GAC Aion V recharges to 80% of its capacity in just 8 minutes. Until now, fast charging with conventional batteries is around 30 minutes.
These figures allow electric cars to equip fuel cars for refueling, without increasing the price, since graphene batteries have no extra cost.
We will see if the Chinese manufacturer can deliver on its manufacturing promise in September, and if the medium and long-term performance of these graphene batteries is similar to lithium-ion batteries. If so, we can be before a new era in the evolution of electric cars.
