An international team of scientists found that in batteries is expensive and relatively rare alkali metal lithium can be used cheap and more common sodium.
Such a move will reduce the cost of batteries without sacrificing capacity. However, sodium is necessary to “fold” in a special way, said ixbt.
The sodium atoms must be placed in several layers, one above the other. Such a structure can be formed by transition of atoms from a piece of metal in the space between the two sheets of graphene under high voltage.
It is now performed only numerical simulation, but it opens the way to the next step that needs to be done by scientists. We are talking about the creation of an experimental sample and study it in the laboratory.
Now development needs to be tested before a new technology
If development is successful, you can count on a new generation of sodium batteries. They will be the same or even larger than lithium-ion batteries, but several times cheaper.
