This involves an impure copper anode and a pure copper cathode. At the anode, copper atoms lose electrons and go into the solution as ions. Therefore the anode decreases in size and the impurities fall to the bottom of the cell. At the cathode, these electrons are then gained to form purified copper atoms. Therefore the cathode increases in size.

Comprehensive characterizations confirm that the Cu 2– x Se cathode undergoes reversible copper ion extrusion/reinjection during the discharge−charge steps. This work suggests the great potential for exploring high-performance electrode materials based on ionic displacement mechanism for advanced multivalent-ion secondary batteries.

There are a few main types of displacement reactions, so let's go over them one by one. Hydrogen Displacement. Some metals are capable of displacing hydrogen (H +) in the form of H 2 gas from water and acids. The reactions where hydrogen gas is released by displacing the H + ions are called hydrogen displacement reactions.

A student was given two metal strips X and Y alongwith colourless silver nitrate solution to perform two separate displacement reactions. When the student placed metal strip X in silver nitrate solution for a considerable time, he observed that the solution turned blue and a coating of silver metal was formed on the strip.

And it is obvious that the copper(II) sulfate has gone because of the lack of blue colour in the solution. The iron has replaced the copper and formed iron(II) sulfate solution instead. We call this a displacement reaction - you can think of the copper as being pushed out of the compound by the iron.
