According to the Spanish "Le Monde" news, the main reason for manufacturers to give up the production of electric vehicles is the problem of battery power. The industry requires increased battery efficacy and duration to reduce charging time. This headache can be solved immediately. The Grapheneo company (a company that produces graphene on an industrial scale) cooperated with the University of Corvarado in Spain to develop the first graphene polymer battery. The company will put it into production next year. Two of the top four German automakers (now not transparent names) will test this battery with electric cars this month.
In 2004, graphene discovered at the University of Manchester, Dr. Andre Heim and Dr. Konstantin Novoselov, that this material has amazing properties. It is thin, superconductor and highly transparent. And very hard. Although people have been thinking that these materials will bring about major changes in the battery field over the years, it is actually very difficult to put it into production in large quantities. However, in 2012 Graphenano became the first company in the world to produce graphene on an industrial scale. Since then, this company has been mainly engaged in accelerating the application of this research called "the material of God." Finally made a battery with it.
This new technology is to make graphene polymer. Its advantages lie in its energy density, duration, charging speed, weight and price. The company's vice president emphasized: "It means a leap in the aviation industry, the automotive industry, the computer industry, and the energy industry. It can greatly increase industry efficiency, and it can make some of the previous imagination possible."
This new product has excellent performance far beyond other products on the market. A lithium battery (in the most advanced state) has a specific energy value of 180 wh/kg, and a graphene battery has a specific energy of more than 600 wh/kg. In other words, its storage capacity is three times that of the best products on the market today.
The battery life is also very long. Its service life is four times that of conventional hydrogenated batteries and twice that of lithium batteries. Electric vehicles that use it to provide electricity can travel up to 1,000 kilometers. It takes less than eight minutes to fully charge it.
The characteristics of graphene also make the weight of the battery can be reduced to half that of conventional batteries. This will increase the efficiency of the machine that loads the battery. The University of Cordoba is studying how to reduce the battery volume to make the battery look more perfect. Due to the excessive density of graphene, it can only be applied to electric vehicles (including automobiles and boats, etc.). The research team hopes to reduce its size in the future so that it can be applied to electronic devices such as mobile phones.
Low cost is another advantage of graphene. The company that produces this battery says that its cost will be 77% lower than lithium battery. It is the price that consumers can afford. Therefore, it will be able to be used in some existing equipment and vehicles, avoiding the problem of incompatibility with the infrastructure.
The University of Cordoba has successfully produced prototypes of this type of battery. It is expected that such batteries will be used in Spain in the first quarter of 2015. And the two German automotive companies mentioned earlier will use the technology in cars to test and accelerate the implementation of this work.
