Cathodes and Anodes are electrodes of any battery or electrochemical cell. These help in the flow of electrical charges inside the battery. Moreover, the cathode has a positive charge, where reduction occurs (receives electrons). In contrast, the anode has a negative charge, where oxidation occurs (loss of electrons) and electricity is produced.

Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode. Cathode active material in Lithium Ion battery are most likely metal oxides. Some of the common CAM are given below

Damage to the electrodes. The lead at the negative electrode is soft and easily damaged, particularly in applications in which the battery may experience continuous or vigorous movement. Stratification of the electrolyte. Sulfuric acid is a heavy, viscous liquid.
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?
The positive electrode has a higher potential than the negative electrode. So, when the battery discharges, the cathode acts as a positive, and the anode is negative. Is the cathode negative or positive? Similarly, during the charging of the battery, the anode is considered a positive electrode.
