Electrode paste selection and battery performance optimization

With the rapid development of science and technology, battery as a core component of many electronic devices, its performance directly affects the use of equipment experience. Electrode paste is an integral part of the battery manufacturing process, and selecting the right electrode paste is crucial to optimize battery performance. This article will explore how to select the right electrode paste to optimize battery performance.

First, the role of electrode paste

Electrode paste plays a role in connecting the active substance and the fluid collector in the battery. It is a sticky paste that can adhere the active substance particles to the surface of the fluid collector, thus forming a conductive electrode. The performance of electrode paste has a direct impact on the battery's charge-discharge performance, cycle life and safety.

Second, the selection principle of electrode paste

1. Compatibility with active substances: the electrode paste should have good compatibility with the positive and negative active substances of the battery, and can form a stable interface, reduce the interface resistance, and improve the charge and discharge efficiency of the battery.

2. Good bonding performance: the electrode paste should have appropriate bonding performance, which can firmly adhere the active substance particles to the fluid collector surface to prevent the active substance from falling off during the charging and discharging process, thereby improving the cycle life of the battery.

3. Good electrical conductivity: electrode paste should have good electrical conductivity, can provide low resistance, improve the battery charging and discharging efficiency and power performance.

4. Stable chemical properties: the electrode paste should have stable chemical properties, and does not decompose or react within the operating temperature range of the battery, and does not affect the safety and life of the battery.

Third, optimization strategy of electrode paste

1. Choose the right binder: The binder is the key component in the electrode paste, and its performance directly affects the bonding performance and conductivity of the electrode. Selecting the appropriate binder can improve the electrode stability, reduce the interface resistance, and improve the charge and discharge efficiency of the battery.

2. Optimize the formula of the electrode paste: by adjusting the proportion of each component in the electrode paste, the viscosity, solid content and conductivity of the electrode paste can be optimized, so as to improve the charge and discharge performance and cycle life of the battery.

3. Optimize the preparation process of electrode paste: By optimizing the preparation process of electrode paste, such as stirring speed, stirring time, etc., the uniformity and stability of electrode paste can be improved, thus improving the performance of the battery.
