Scientists have invented an environmentally friendly battery
Source:Traditional battery elements is high time to find a replacement
The Invention of laptop lithium-ion batteries (or simply to say batteries) made at the time a real revolution. But it later emerged that the elements that make up these batteries are not so easy to dispose of. And in General they are quite dangerous for the environment. However last researches of European scientists can bring another revolution, because they managed to develop environmentally friendly batteries than standard batteries.
According to the publication , with the study are experts of the Technological University of Chalmers, Sweden, and National Institute of chemistry, Slovenia, and the basis is the concept of the use of aluminum as the main component. The use of technology aluminum battery can provide several advantages, including high energy density, and the fact that there is already an established industry producing and processing this metal. Compared to today's lithium-ion batteries, the new approach of researchers can lead to significantly lower production costs.
Material costs and the environmental impact that we expect from our new development is much lower than what we see today, which makes their use possible, for example, storing energy from solar cells. — said one of the authors, Professor in the Department of physics of the Technological University of Chalmers Patrick Johansson.
How the batteries of a new type
It is Worth noting that attempts to use as the main power element aluminum have been made previously, but then in the design of aluminum panels used aluminium as the anode (negative electrode) and graphite as the cathode (positive electrode). However, graphite is quite ill-suited for these purposes, in particular due to the fact that not the best way affects the battery capacity.

But the new design graphite was replaced by the organic cathode made of carbon molecules of anthraquinone. Anthraquinone — it is practically insoluble in water and organic solvents substance composed of atoms of carbon, hydrogen and oxygen. In industry it is sometimes used as a dye.
The Advantage of this organic molecule is that it allows «catch» positively charged particles from the electrolyte and store them in a fairly large number, which makes possible their application in batteries. Do you believe in the prospect of such developments? Write about it in our .
Because the new cathode material enables the use of more suitable carrier of the charge in the battery to unlock the potential of aluminium. Now we continue working on improving technology and looking for the best electrolyte. The current version contains chlorine, but we want to get rid of it.
Of Course, on the commercial use of technologies to speak while early. As it is premature to argue about «death» lithium-ion batteries. The more that scientists themselves are not focused on it. Their main task is to provide a safe for the environment (but not in favor of the reduction of capacity and easy) alternative to traditional batteries, which will ensure a smooth transition .
