Hint: In order to answer this question, to know the exact term for a negative electrode or the term which is called negative electrode, we will go through the term and then we will discuss why the required term is called a negative electrode. Complete answer: The negative electrode in electrolysis is called the cathode. The positively charged ions move towards the cathode.

The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
During discharge, the positive electrode is a cathode, and the negative electrode is an anode. During charge, the positive electrode is an anode, and the negative electrode is a cathode. An oxidation reaction is an electrochemical reaction that produces electrons.
During normal use of a rechargeable battery, the potential of the positive electrode, in both discharge and recharge, remains greater than the potential of the negative electrode. On the other hand, the role of each electrode is switched during the discharge/charge cycle. During discharge the positive is a cathode, the negative is an anode.
The anode is one of the essential components of the battery. It is a negative electrode which is immersed in an electrolyte solution. So, when the current is allowed to pass through the battery, it oxidizes itself, and the negative charges start to lose and travel towards the positive electrode. What is the Battery Cathode?
While the lithium-ion anode is present opposite to the cathode, it has a negative charge. Hence, it undergoes an oxidation reaction during the charging and discharging of the battery. What Is Lithium Battery Anode Materials?
In contrast to the anode, the cathode is a positive electrode of the battery. It gets electrons and is reduced itself. Moreover, the cathode is immersed in the battery's electrolyte solution. So, when the current is allowed to pass, the negative charges move from the anode side and reach the cathode.
