Application of bis-(2-dimethylaminoethyl) ether in the sealing of battery packs of new energy vehicles

Introduction

With global emphasis on environmental protection and sustainable development, the market demand for new energy vehicles (such as electric vehicles) has grown rapidly. One of the core components of new energy vehicles is the battery pack, and its performance and safety directly affect the range and service life of the entire vehicle. The sealing performance of the battery pack is one of the key factors in ensuring the safe operation of the battery. As a high-performance chemical material, bis-(2-dimethylaminoethyl) ether (hereinafter referred to as “bis-ether”) has gradually attracted attention in the application of new energy vehicle battery pack sealing in recent years. This article will introduce in detail the characteristics, application scenarios, product parameters and their advantages in battery pack sealing.

Basic Characteristics of Bis-(2-dimethylaminoethyl) ether

The importance of battery pack sealing

The battery packs of new energy vehicles are usually composed of multiple battery modules that need to work in a sealed environment to prevent moisture, dust and other contaminants from entering. The sealing performance of the battery pack directly affects the safety, life and performance of the battery. If the seal is poor, the battery may be short-circuited, overheated or even moreTo serious problems such as fire.

Advantages of bis ether as sealing material

1. Excellent sealing performance: Bi-ether has low viscosity and good fluidity, and can effectively fill tiny gaps in the battery pack to form a uniform sealing layer.
2. Good thermal stability: Bis ether can still maintain its performance in high temperature environments, and is suitable for the sealing needs of battery packs under high temperature operating conditions.
3. Chemical corrosion resistance: Bi-ether has good tolerance to electrolytes and other chemicals that may exist in the battery pack, and can maintain a sealing effect for a long time.
4. Low Volatility: The low volatility of bis ethers reduces its evaporation loss under high temperature environments, ensuring the long-term stability of the sealing layer.

Application Scenarios

1. Sealing between Battery Modules: Bi-ether can be used to seal the seam between battery modules to prevent electrolyte leakage and external contaminants from entering.
2. Sealing of Battery Pack Case: Bi-ether can be used to seal the battery pack housing to ensure the sealing performance of the entire battery pack.
3. Sealing of Battery Connectors: Bi-ether can be used for sealing of battery connectors to prevent corrosion and failure of connectors due to environmental factors.
