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.

Q4为什么我们需要形成过程?

有机溶剂在充电过程中容易在负极上分解,导致电池膨胀,电池容量下降以及由活性反应引起的不安全。形成过程的目的是形成称为固体电解质界面(SEI)的固体层,其是电绝缘的,但提供显着的离子导电性。这种界面阻止了第二次充电后电解液的进一步分解
