The University of Manchester (the University of Manchester) National Institute of Graphene (Graphene Institute) researchers use of Graphene as add material, is committed to explore to reduce size and weight of the battery and all kinds of new methods of extending battery life.
In an article entitled, "to the Graphene material in Electrochemical Energy Storage" (Electrochemical Energy Storage with Graphene - Enabled Materials) research program, the researchers is collaborating with several companies, including Rolls Royce (Rolls-Royce), Sharp (Sharp) and Morgan Advanced Materials (Morgan Advanced Materials), etc. These business partners to play a key in the development of the future applications of graphene. At present, the Graphene @ Manchester is from the global more than 30 enterprises jointly launched research plan and application.
Professor of the department of electrical and electronic engineering at the university of Manchester, Andrew Forsyth, before we develop the battery, we must first eyes how graphene, and chemical composition (especially the electrolyte). University chemistry professor Robert Dryfe with experimental analysis of chemical interaction between graphene and lithium ion. Professor Dryfe and explore electronic can more quickly through the graphene and can be stored in the capacitor size on the surface of the graphene.
Another priority of the plan is based on the graphene supercapacitor usually has a high power performance and longer than the battery life, but the storage capacity is low. However, researchers are still bullish on batteries as part of reinforcing the integrated storage solutions.
According to Forsyth, said professor graphene battery and super capacitor combination, can bring electric car sales powerful driving force. At present, the green car use up to 200 kg in weight of the battery, it's about three the weight of the passengers. Through reducing the weight of the battery, graphene will be beneficial to improve energy efficiency, and increase range of electric vehicles to achieve more than the current limit, about 100 km.
Professor Forsyth stressed that if we are able to extend electric range between two stations, should immediately make electric cars become popular. But what can a battery breakthrough driving restrictions in real life? Electric vehicles, like all the other cars still can't drive. Like drivers during acceleration, for peak power demand sharply, will bring pressure for batteries, but they may also limit its service life.
To test the prototype of the combination of graphene battery and super capacitor is qualified for the job requirements, professor Forsyth through exposing it to the real world to simulate different driving situations under pressure. He said, we can even test driving in extreme climate conditions of driving technology. Many batteries in cold weather conditions is difficult to play a role, can be found through our climate chamber any weakness.
Of course, storage is not limited to transmission based on graphene. As Britain has become more dependent on renewable energy, it also will be the future of the state grid play an important role. Professor Forsyth question, if we only rely on solar and wind energy to produce energy, one day when covered with dark clouds and wind again how? If we are able to develop high capacity storage mechanism, owners will be able to advance battery for a rainy day.
