Graphene Battery -- The Tesla of Tomorrow?

A graphene battery is a novel battery made of graphene, a carbon atom in a honeycomb pattern sheet. The rumor is that Tesla is working on a car graphene battery that can be five times faster than a regular battery.

With electric cars get more and more market share, the implementation of the new battery technology is, in order to improve the scope and efficiency. Graphene battery is one of the new technology can be applied to electric vehicles.

Is one of the biggest problems of electric cars using the battery's big and heavy. These batteries need to be a long time to recharge and run out of energy, and fast. In order to solve this problem, many people are looking for graphene battery as a solution. Last year, a student at the university of Sussex engineer to design a new type of graphene battery, may completely transformed the landscape of electric cars. Graphene batteries can be in many different ways to improve the current battery technology, such as providing longer battery life and performance.

What is Graphene ?

Because of the structure of graphene and graphene battery can provide higher performance than conventional batteries. Graphene by together the carbon atoms of honeycomb structure. Graphene structure is very thin, basically be two-dimensional.

Graphene is thermal energy and power of a good conductor. Graphene is chemical inertness, with large surface area, but still is flexible, and very light. Graphene is usually considered a sustainable and environmentally friendly, has a number of different possible applications.

The hexagonal thin structure of graphene

Electronic usually has a small effective mass associated with them, as long as they are through the solid structure, which limits their movement. This is what they interact with all other particles around the results. Because the graphene sheet is two-dimensional, so it won't happen these interactions with the other particles, therefore the electrons in graphene as if no quality work. They can be fast moving in space, almost move at the speed of light.

This unique behavior that graphene has so excellent electrical conductivity, can than copper conductive nearly 35%.The electronic transport through the graphene is 1000 times better than through silicon, which helps why computer based on graphene transistor has thousands of times faster than the current silicon-based computer's potential. This is also why graphene always maintain minimum conductivity.

The battery application of graphene

With graphene in battery applications, when used in combination, the performance of the batteries can be significantly improved. Graphene battery charge is perfect for a shorter time and high energy storage capacity. Battery materials or the amount of carbon in the battery electrode negative correlation with the life of the battery, but graphene can improve conductivity, without the need for batteries used in the same amount of carbon.

Graphene can improve all aspects of the battery, such as energy density and structure. The traditional Lithium ion batteries Can pass to graphene and battery combination to improve. Battery anode can add graphene, through the electrical conductivity of the material can be used to optimize the performance of the battery.

Also can improve the battery hybrid materials. Graphene and vanadium oxide can be together, to provide ability of fast charging and discharging lithium ion cathode. Composite material also can improve the durability of the charging cycle and conductivity. Vanadium oxide has a poor electrical conductivity, but through the use of graphene as oxide can be attached to the skeleton, it creates a kind of excellent capacity and the conductivity of the mixture.

Lithium ion rechargeable batteries can also use graphene for improvement. Lithium iron phosphate (LFP) batteries have higher overall power density than other lithium ion battery, but their energy density was lower. Graphene can be used to enhance the LFP cathode, make a battery lighter weight and a greater storage capacity, charging speed than normal Lithium iron phosphate batteries Much faster.

Graphene battery and super capacitor combination can greatly improve the efficiency of the electric car trip range and, electric car companies have investment in the development of car with graphene batteries.

Graphene batteries in electric cars

The new progress of graphene battery has led to the creation of the battery than the currently used any performance of lithium ion batteries. Graphenano Spain's battery last year launched a graphene Polymer battery, a charge can make electric cars travel 800 km or 497 miles. In theory, battery charge can also be in a few minutes. Due to its structure of graphene, battery charging and discharging ability about 33 times faster than normal lithium ion battery.

Fisker, operated by Henrik Fiske, perhaps is the biggest competitors, Tesla electric car success originally planned to use in its new electric car FiskerEMotion graphene batteries. Later, however, the plan for lithium ion batteries. Although decision graphene will be used in electric vehicle battery as an alternative, but Fisker, said the company to solid graphene battery cell research will continue.

If Fisker decide the use of graphene in their vehicle batteries, they are probably the first company to do so. That is to say, it is not like Tesla sitting on the sidelines, while other companies pursuing the progress of the electric vehicle technology. If batteries are graphene as a transformative technology, Tesla will to some extent, the pursuit of the possibility of its use.

At the same time, research on graphene batteries is continuing, just as super capacitors using graphene can do, and traditional batteries may be eliminated in the near future. The super capacitor consists of three layers. It has two layers of graphene, and the middle layer is a layer of electrolyte. Super capacitor film is very thin and stable, and can release a lot of energy in a very short time, which is necessary for electric vehicles to need additional energy to rapidly increase acceleration.
