Aluminum and Graphene Batteries: abandon lithium with a much better accumulator
Graphene is a material with exceptional potential from a physical point of view, with an enormous ability to accumulate electrical charges, so it could be the solution for future storage systems. In this case it would be essentially aluminum – graphene batteries, which have already been built at the prototype level by several companies.
Graphene is referred to as a two-dimensional (2D) structure of graphite, in which a flat layer of carbon atoms is organized into a supporting honeycomb lattice. Graphene-based materials have high porosity and larger surface area and are extremely strong and lightweight. Furthermore, these materials possess a high charge capacity and flexibility and are good conductors of thermal and electrical energy, making them a suitable material for storing energy. Graphene, as well as in specific aluminum-graphene or sodium graphene batteries, can also be used inside accumulators already present, as an element of efficiency.
Graphene's high electrical conductivity increases electrode density and accelerates the chemical reaction within the battery, allowing for greater power transfer and faster charge rates with less heat. Graphene also undergoes less degradation than lithium, offering improved performance, which substantially extends the life of electric vehicle batteries. Furthermore, graphene batteries are also affordable and sustainable compared to other electric vehicle batteries.
Now the problem of graphene was the production cost that could reach up to 15 thousand dollars per kg, but now new techniques. Just recently it became known that Russian and Finnish scientists were able to synthesize graphene at low cost starting from carbon, with the chemical vapor deposition (CVD) technique. This would make it possible to abandon the prototyping phase of these batteries and therefore move on to the pre – industrialization phase.
Graphene is much more stable than lithium and very easy to recycle. But what happens to all the companies that have invested heavily in the rare metal?
