SPL: "Electron particle flow," whatever that is, does not cause cables to break down, or wear in any way. Neither, in general, does passing a current through a wire. If it did, you'd have to rip out all the wiring in your house every few years and replace it.
I assume your friend is not trying to sell you cables. However, people who do sell cables are prone to this sort of nonsense claim (for obvious reasons). Your friend may have heard this somewhere and didn't realize he was being spun.
