ELECTRODE IN GRAPHENE – The future of electric cars has good prospects for development? To make it believe are the continuous posts of the development of innovative technologies that help overcome the current obstacles of vehicles with “shock”: the high cost of the batteries and the limited autonomy by today’s lithium-ion solutions. The latest research published in order of time is that of researchers at the University of Cambridge on the lithium-oxygen technology for some time to the study and to which the British researchers gave further development thanks to the use of lithium hydroxide in place of lithium peroxide and graphene for the electrode.
AS GASOLINE – According to the Cambridge scholars prototypes of lithium-oxygen would be more stable and efficient than in the past and would ensure energy density than ten times the current lithium-ion batteries, which would be capable of storing ten times more energy for a given weight. A result comparable to that of gasoline which would allow much of increasing the autonomy of the electric car. Other positive properties of new accumulators would be the possibility to reduce to one fifth the weight of the batteries and to cut by 80% the production costs. One factor, the latter, which would contribute greatly to limit the high price lists of zero-emission models available today. A well would improve the duration, estimated at more than 2,000 complete charge cycles, about double that provided by lithium-ion battery systems.
DEVELOPING LONG TIME – If the future prospects are encouraging, the time to see the market actually accumulators lithium-oxygen does not appear short. Clare Grey, the Cambridge professor who led the research, called the project “a step toward an ideal battery, although with many obstacles to come.” According to the scholar, in fact, you may need to be even more than a decade to develop the technology to use it in series production, especially due to the still too low speed of charge obtained. In other words, it would be still to solve the third limit of electric cars: the long period of “supply.”
