The Anatomy of a Battery
The completely flat end of the battery has a minus (−) sign next to it. This is the negative end of a battery, or anode . Depending on the battery type, there is also a liquid, solid, or paste/gel, called an electrolyte .

Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
There are three main groups of negative electrode materials for Li-ion batteries. The materials known as insertion materials are Li-ion batteries' “historic” electrode materials. Carbon and titanates are the best known and most widely used.
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
The electrodes are the heart of the battery where all the electrochemical reactions occur. Testing of the electrodes prior to battery assembly provides insights into their composition, morphology and electrochemical performance.
Cathode and Anode materials are a part of every battery solutions because this is the main source of how the working of a battery is enhanced or properly stimulated.
Essentially, many electrochemical cells joined in parallel or series are known as a battery and they provide capacity and voltage. A negative (anode) and positive (cathode) electrode are in each cell, separated by an electrolytic solution, known as an electrolyte. The transfer of the ion between the electrodes is allowed by the dissociated salt.
