Q4 Why do we need formation process ?

Organic solvents easily decompose on the negative electrodes during charging ,leading to battery swelling,drop of cell capacity ,and unsafety caused by active reaction.The purpose of the formation process is to form a solid layer called the solid electrolyte interphase (SEI),which is electrically insulating yet provides significant ionic conductivity. This interphase prevents further decomposition of the electrolyte after the second charging.
