Pakistan 17.2: Electrolysis - Chemistry LibreTexts
In any electrochemical cell (electrolytic or galvanic) the electrode at which reduction occurs is called the cathode. The positive electrode, on the other hand, will attract negative ions (anions) toward itself. This electrode can accept electrons from those negative ions or other species in the solution and hence behaves as an oxidizing agent.
Pakistan Intercalation chemistry of graphite: alkali metal ions and ...
Learning from past lessons on alkali metal intercalation in graphite, recent breakthroughs in sodium and potassium intercalation in graphite have been demonstrated for Na-ion batteries and K-ion batteries. Interestingly, some significant differences proved to exist for the intercalation of Na + and K + into graphite compared with the Li + case.
Pakistan Graphite Electrode Anion Or Cation - Image Results
An electrode reaction refers to the net oxidation or reduction process that takes place at an electrode. This reaction may take place in a single electron-transfer step, or as a succession of two or more steps. The substances that receive and lose electrons are called the electroactive species.

Pakistan Electrolysis of ionic compounds - What are electrolytes and ...
Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath. They are typically made using premium petroleum needle coke, coal tar pitch, and some additives (Fruehan, 1998 ). Specification of needle coke for the manufacture of large diameter graphite electrodes is shown in Table 12.12.
