Sodium-Ion Battery Shows Promise In New Study Despite Lower Energy Density
The name of the game is macrocyclic molecule.
Apart from researching complex chemistries with high energy densities, scientists also want to create great batteries with common and abundant elements. Sodium, for example. Cells with this component always had issues. A new prototype – created by an Imperial College London team – managed to overcome most of them apart from lower energy density. That may give us sodium-ion batteries with some more work. Call them Na-ion.
This new idea relies heavily on macrocyclic molecules, made from hydrogen and carbon. Yes, these batteries use organic components. Did we mention scientists have already researched the use of sugar in cells? Some are probably still trying to make one.
Macrocyclic molecules are not sugar, but rather cyclophanes. The best property of these chemical compounds – more specifically of paracyclophane‐1,9,17,25‐tetraene – is accomodating the big sodium ions in a sort of net, which the scientists prefer to call a ring structure. The one you can see right below.
