1. Battery Adhesive

Lithium battery pole pieces are mainly composed of active materials, conductive agents, and binders. Usually, binders are inactive materials and account for a small proportion of the electrode. However, binders are an indispensable and important component in the preparation of lithium batteries, and play an important role in maintaining the integrity of the electrode structure and improving the electrochemical performance of the electrode.

1. What is electrochemical impedance spectroscopy (EIS)? 🔍

1️⃣Electrochemical impedance spectroscopy (EIS) is a non-destructive parameter determination and effective method for determining battery kinetic behavior. A small-amplitude sinusoidal voltage signal with a frequency of w1 is applied to the battery system, and the system generates a sinusoidal current response with a frequency of w2. The change in the ratio of the excitation voltage to the response current is the impedance spectrum of the electrochemical system.

Polymer and its derivative binders

1 Cellulose binder

Sodium carboxymethyl cellulose (CMC) is a cellulose binder that has been widely studied. It is a carboxymethylated derivative of cellulose. CMC is an ionic chain polymer water-based binder that forms a transparent viscous glue after swelling with water. It has the advantages of being difficult to ferment, good stability, low price, safety and environmental protection.
