Apple is working with an electric car battery manufacturer to discuss together to solve the legal proceedings, this battery manufacturer accused Apple of illegal employment of their key engineers, and work for Apple's new battery business.
A123 Systems filed in Massachusetts last month to federal court lawsuit against Apple and five former employees of A123 Systems, which several Apple employees now work. The lawsuit against Apple in the last year has taken "aggressive actions", which won over the implementation of key development and testing activities of employees. The lawsuit seems to provide further evidence that Apple has developed an electric vehicle that goal.
On Tuesday, Apple has made an application to the court, and they hope to get more time to respond to the lawsuit, they said it is exploring alternatives and potential plaintiffs plan to solve this problem.
A123 Systems is committed to developing an energy storage system that is suitable for a variety of commercial and industrial applications, including advanced energy storage for electric vehicles. A123 Systems for the bus company to build lithium-ion hybrid system to any other manufacturer in the world to be more than.
Apple hired five employees accused of execution in the lawsuit with Apple in the same function, in violation of the employees to sign non-compete and confidentiality agreements. Although in many US states that non-compete clause in the law is enforced without, but in Massachusetts, which is A123 Systems is allowed to sue the place of the agreement.
Apple rumors began to develop electric cars last month, rumors indicate that Apple is the formation of a team responsible for the design of electric vehicles, this team is by Tesla and other auto companies to recruit people who co-founded. And A123 Systems developed technology will be the key technology for electric cars on the roads.

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 the Tesla product, after 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 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 [microblogging] represented by nickel-cobalt-aluminum lithium batteries (lithium cobalt oxide battery), represented by BYD lithium iron phosphate and to Japanese automakers as the representative of 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 uses an upgraded version of Roadster3.0 had improved lithium battery, 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, up to 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.
The main reason is that the market difficult to use the convenient degree: First lower the mileage, 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 ModelS85 Tesla, 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."
Li Yichun, said the current domestic battery graphene research progress on smoothly, some universities and R & D team in Shenzhen enterprises to cooperate, research has entered the pilot phase, "the first half of 2015 it is possible to mass production, the performance will be a lot upgrade, such as without increasing the amount of cost in the premise, to increase the number of charging and discharging lithium, and the like to improve the battery safety. "
China graphene industry technology strategic alliance in 2013 had been reported to the national ministries of multiple graphene research bases, Wuxi, Chongqing, Nanjing, Qingdao, Changzhou, etc. have established graphene industry demonstration base. December 2014, Chinese President Xi Jinping visits the high-tech industries in Jiangsu Research Institute, the research and development of graphene visit Products.
However, according to graphene cell research said that the current study is the major domestic graphene applied to the lithium battery, rather than a new system of "super batteries", so the domestic technology and super batteries have a certain gap. The relevant state departments this very seriously, in 2015 introduced the "Thirteen Five" plan new material graphene may be included.
