Thread: Electron transfer without mass transfer?

Is it possible to create electrochemical system in which electron transfer would happen without transfer of matter?

An electron is a part of matter, albeit a quirky part that follows some really strange rules. If you have any sort of transfer of an electron, you are transferring matter.

One great disadvantage of batteries is limited number of cycles.Supercaps do not have ion transfer and could be recharged for hundreds thousands of cycles.
1)Still there is some pseudocapacitive reactions such as when redox pairs such as Fe2+/Fe3+ and S2-/S22- are dessolved in electrolyte and there could be reactions like
[Fe(CN)6]3- + e «----» [Fe(CN)6]4-
Is it able to sustain very many cycles of recharges?
2) In P-n junctions there seem also exist some type of electron-hole diffusion.Could it be exploited as chemical enegy storage?
3)Some materials such as ferroelectrics are able to store energy in polarization even if there is no free charges present.
Do exist some electrochemical analog of electrostatic polarisation?For example,I could imagine some crystal in which under certain conditions shift of chemical energy occur.Then one part of crystal will behaive as reducer and the other end as an oxidizer.If we will connect both ends with some conductive material electromotive force would be created and chemical enegy will start to equilize exacly as heated pyroelectric or ferroelectric gives off energy.This material is hypothetical.

Electrochemical like blender, so atoms regroup. No large-scale electronic transfer, if there is a large-scale electronic transfer, will produce lightning.

What about induction, or the principal involved in how a transformer works. Current is changed to an electromagnetic field, which is then convered back to current in the adjoining transformer coil.

Is mass transferred in this case?
