Graphene batteries: uses and characteristics of this new technology
The characteristics and properties of graphene batteries have led to this material being linked to the future for revolutionizing the performance and lifetime of, among other things, batteries.
Since its potential applications have been outlined, much research has been conducted with the goal of finding practical uses for graphene to overcome the current advantages of lithium batteries.
What is graphene?
Graphene is an allotrope of pure carbon, i.e. it has a flat hexagonal molecular structure with a lamellar structure. Unlike graphite, graphene has an ordered structure and graphite can be understood as many interleaved and disordered graphene sheets. It is one of the strongest materials in existence, but it is also flexible and very light, which allows it to adapt to the needs of each area.
Because it is a superconductor of heat and electricity, it has been used in recent years to double the useful life of batteries, as well as to give them greater charging capacity in a shorter time.
Currently, lithium batteries are the most widely used due to their characteristics; however, graphene batteries offer the world a better outlook for cell phones, motorcycles, bicycles, electric cars, etc.
Uses and characteristics of graphene batteries
Energy density and charging speed
One of the main characteristics of graphene batteries is that they achieve a much higher energy density than lithium batteries, i.e. they store more energy and do so with a higher charging speed.
Imagine that with a battery of this type we would only need about 10 minutes to fully charge an electric vehicle or a cell phone, which also adds greater autonomy to the list of benefits
Safety and flexibility
By not using liquid electrolytes it minimizes the risk of explosion, so using devices with graphene batteries is much safer.
Due to the composition of the carbon atoms in hexagonal form, this material is extremely flexible and thin so it adapts to the conditions according to the requirements.
Service life and stabilityele
Graphene provides structural stability which means that the anode volume of the batteries does not change with each charge and discharge cycle. This results in a much longer life compared to other types of materials.
Environmentally friendly
Not having to replace batteries frequently adds a point for the care of the environment. In addition, graphene is capable of producing energy by exposure to sunlight, which also adds it to the list of green energies.
