Graphene Battery or Production of New Energy Vehicles Will Be Accelerated

December 26, 2014, the US electric carmaker Tesla released an updated version of the discontinued two years ago, the first generation model Roadster, the mileage of 644 km, 60% higher than the original.

Advances in battery technology, to enhance the performance of Tesla products. Prior Roadster Mileage is 393 km. Tesla CEO Musk said Tesla high-performance graphene battery, compared to the current capacity increase of nearly 70 percent.

British scientists have invented graphene after 10 years, the application of the battery with great breakthrough. In early December, the Western media reported that Spain and the Spanish company Graphenano Cordoba University to develop graphene battery, a charging time of just eight minutes, can travel 1000 km. It is graphene researchers called "super cell."

"We still understand the situation, the specific situation in Spain is proving such a battery, if this is confirmed, it is indeed a revolutionary change out." China graphene industry technology strategic alliance Secretary-General Li Yichun on December 24 21st Century Business Herald reporter said.

Spain's "super cell" will soon be used in the same car as the Tesla, according to Western media reports, its owner in December to test the two German auto giant cars, and production in the first quarter of 2015 listed use.

Charging time close to refuel graphene

Currently, the global automotive battery manufacturers use lithium batteries are mainly used to Tesla as the representative of a nickel-cobalt-aluminum lithium batteries (lithium cobalt oxide battery), represented by BYD lithium iron phosphate and Japanese vehicles as the representative manganese lithium batteries.

These three types of battery with the highest energy density of lithium cobalt oxide, but it is also the most unstable at high temperatures; lithium iron phosphate, the most stable, but the lowest energy density.

Lithium-ion battery technology, has been quiet for 20 years without major technical innovations. A study of battery power, experts say, the biggest obstacle is the limited power density lithium-ion battery, it can not quickly receive large amounts of energy or release.

Tesla Roadster 3.0 uses an upgraded version of an improved lithium battery too, Tesla did not confirm whether or not to join the graphene. However, its performance has greatly improved, I am afraid only of graphene can do. The new and improved lithium battery capacity 18650 significantly increased, the number 6831 of the battery pack does not increase, the total capacity of the battery pack from 53kWh increased to 70kWh.

According to interviewed experts, graphene structures can change the long-term there is no breakthrough in battery technology barriers. The internal structure of the graphene sheet interval extended to allow more electrolyte "wetting" and a lithium ion battery performance of a lithium ion to obtain a high rate channel.

"Graphene is characterized by conducting fast, good conductivity, many studies are currently in the experiment, it is difficult to say exactly which one, but shorten the charging time is for sure." Li Yichun said. According to the United States is expected to Rensselaer Polytechnic Institute researchers, graphene anode material charge or discharge 10 times faster than today's lithium-ion battery in a conventional graphite anode.

According to the data of these institutions in Spain, graphene has the potential to significantly increase the capacity of the battery. "Super Battery" parameter display, the energy density of more than 600wh / kg, is five times the power lithium battery; lithium battery life is doubled; it costs 77% lower than the current lithium batteries.

Lithium traditional manufacturing powerhouse, Japan and South Korea, in the graphene battery technology they are to snatch the initiative, South Korean scientists as early as last November announced graphene super phone battery latest invention, can store the same amount of conventional batteries power, but the charging time of just 16 seconds.

Japan implemented in two lines parallel battery technology, in addition to the development of lithium batteries in the ordinary sense, they also studied the fuel cell technology, an alternative material graphene with a special platinum as a catalyst, to produce hydrogen fuel cell vehicle fuel required to obtain breakthrough.

According to Li Yichun, the current points total of graphene research on two: one for application in traditional lithium batteries, the purpose is to improve and enhance the performance of lithium batteries, these batteries do not have disruptive effects; the second is based on graphene create a new system battery, which is a new series, the performance is subversive, known as "super cell."

China 2015 mass production of graphene lithium battery

The promotion of new energy vehicles in China for five years, but the effect is not ideal. According to the Ministry of Industry statistics show that 11 months of 2014, cumulative production of new energy vehicles 56700, and 2015 pure electric vehicles and plug-in hybrid car production and sales goals and strive to reach a total of 500,000 of the gap is huge.

Difficult market the main reason lies in the convenience of the use of: First, the mileage is low, consumers generally have range anxiety; the second is charging facilities, inadequate charging inconvenient affect use.

In traditional solutions, car prices to promote the use of hybrid mileage relieve anxiety, oil or electricity consumers can choose according to the actual situation; another perspective, the state encourages large-scale construction of the charging station and charging pile, charging ease difficult.

Graphene super battery occurs, it may completely change the existing charging problem. Mileage doubled, long-distance travel mileage anxiety may completely broken. Spanish super battery, for example, almost 1000 km Mileage approaching a straight line from Shanghai to Beijing, far beyond traditional driving distance of a tank of fuel in the car.

Graphene charge faster, you can reduce the charging time, can reduce the charging station and charge a wide range of macro-demand pile. In the current global leader Tesla Model S 85, for example, through the power of its super charging station, have 80 minutes to full, the owner, such as charging time is still an ordeal.

"Super battery 10 minutes of charging time, longer than the first oil plus a little bit of time, but the mileage than a box of oil much longer, consumers never complain." A car industry analysts said.

Currently, hybrid cars are considered to be the best product on the market for the transition from fuel vehicles to electric vehicles, and this transition period may last up to 15-20 years, but advances in battery materials could overthrow this anticipation, even the popularity of electric cars may not need that long.

"Super cell" Once applied to large-scale electric car, the entire industry will be disruptive. "Some hundred car prices may not have the technology and the decline, and some only ten or twenty years of car prices, because the master new material technology, could become the new giant."

2014 China Top 10 Ranking Lithium Battery Company

China is the world's largest lithium battery battery manufacturering base, the second largest producer and exporter of lithium batteries, lithium-powered products have accounted for 40 percent of global market share. Currently, lithium has been gradually expanded to electric bicycles, electric vehicles and other fields. With the continuous expansion of the global lithium demand applications and yearly basis. China is second only to Japan's largest producer of lithium, a huge market growth. Many Chinese companies have increased investment of resources, increased automation or semi-automation equipment, automation and production patterns to semi-automate the transition from labor-intensive to develop technology innovation to further improve the quality system, by improving product quality and labor productivity, and high-end products to high-end market development.

In 2011, China's lithium production was 2.966 billion, an increase of 10.88%, to 2013 lithium battery production reached 4.178 billion, an increase of 40.86%.
