1. Introduction: The rise of new energy vehicles and security challenges

With the increasing global awareness of environmental protection, new energy vehicles (NEVs) have become an important development direction of the automotive industry. However, in this “green revolution”, battery safety issues have always been an unavoidable topic. In recent years, fire accidents caused by thermal out-of-control of batteries have been common, which not only threatens the lives and safety of drivers and passengers, but also has caused considerable obstacles to the development of the new energy vehicle industry.

To solve this problem, scientists have turned their attention to fireproof isolation technology. In this technology, bis(dimethylaminoethyl)ether (BDMAEE) is playing an irreplaceable role as an efficient foaming catalyst. It is like an invisible guardian, silently protecting the safe operation of new energy vehicles. So, what exactly is BDMAEE? How does it help fireproof isolation technology? Next, let us unveil its mystery together.

2. Introduction to Bis(dimethylaminoethyl) ether (BDMAEE)

2.1 Chemical Properties

Bis(dimethylaminoethyl) ether (BDMAEE), with the chemical formula C8H20N2O, is an organic compound with strong alkalinity. As a type of amine compounds, BDMAEE can promote the occurrence of chemical reactions through its unique molecular structure, especially in foamingExcellent catalytic performance was shown during the process.

Molecular Weight: 156.26 g/mol
Melting point: -30°C
Boiling point: 220°C
Density: 0.92 g/cm³

BDMAEE’s molecular structure contains two dimethylaminoethyl groups. This special structure gives it strong nucleophilicity and reactivity, making it an indispensable catalyst in many industrial fields.

2.2 Physical parameters

The following are some key physical parameters of BDMAEE:

parameter name	value	Unit
Appearance	Colorless to light yellow liquid
Solution	Easy soluble in water, alcohols, etc.
Vapor Pressure	0.01	kPa
Flashpoint	85	°C

These parameters show that BDMAEE not only has good stability, but also has high safety, making it very suitable for use in complex industrial environments.

3. Application of BDMAEE in foaming catalysts

3.1 Analysis of foaming process

Foaming is the process of introducing gas into liquid or solid materials to form a porous structure. In new energy vehicle battery packs, foaming materials are usually used as heat insulation to prevent heat transfer between battery modules. As a foaming catalyst, BDMAEE’s main function is to accelerate the progress of foaming reactions, thereby improving production efficiency and material performance.

Basic Principles of Foaming Reaction

The foaming reaction can be summarized simply into the following steps:

Initial Stage: BDMAEE reacts with isocyanate to form active intermediates.
Expandation stage: The active intermediate further reacts with the polyol to form a polymer backbone.
Currecting Stage: The polymer skeleton is gradually crosslinked to finally form a stable foam structure.

In this process, BDMAEE is like a “commander”, accurately controlling the speed and direction of each step of reaction, ensuring that the resulting foam material has ideal density, strength and thermal insulation properties.

3.2 Catalyst performance parameters

To better understand the catalytic performance of BDMAEE, we can refer to the following data:

Performance metrics	Value Range	Unit
Catalytic Efficiency	95%-99%	%
Foam density	30-50	kg/m³
Thermal conductivity	0.02-0.03	W/(m·K)
Dimensional stability	±0.5%	%

It can be seen from the table that the application of BDMAEE not only improves the comprehensive performance of foam materials, but also greatly reduces production costs.

4. Core principles of fireproof isolation technology

4.1 Thermal runaway mechanism

The so-called thermal runaway refers to the phenomenon of a sharp rise in the internal temperature of the battery, leading to a series of chain reactions. Once a battery cell gets thermally out of control, the heat it releases may spread rapidly to the adjacent cell, eventually causing the entire battery pack to burn or even explode.

The main causes of thermal runaway

Overcharge/overdischarge: Too much current or too high voltage may cause a short circuit inside the battery.
External impact: Collision or squeezing may cause the battery housing to rupture.
High Temperature Environment: Extreme high temperatures will accelerate the internal chemical reaction of the battery.

4.2 Selection and design of isolation materials

In response to the problem of thermal runaway, scientists have developed a series of high-performance isolation materials. Among them, the thermal insulation layer based on BDMAEE foaming technology is highly favored for its excellent flame retardancy and thermal insulation properties.

Design Principles

High thermal resistance: Ensure that heat is not easily transferred to adjacent battery cells.
Low density: Reduce overall weight and improve vehicle endurance.
High temperature resistance: It can maintain stable performance under extreme conditions.

Through reasonable design, these isolation materials can effectively prevent the spread of thermal runaway at critical moments, and gain valuable escape time for drivers and passengers.

5. Specific application of BDMAEE in battery packs of new energy vehicles

5.1 The importance of battery thermal management

In new energy vehicles, battery thermal management system (BTMS) plays a crucial role. It not only monitors the working status of the battery, but also adjusts the temperature to avoid excessively high or too low temperatures affecting battery performance. And BDMAEE foaming material is an indispensable part of this system.

Application Scenarios

Isolation between Battery Modules: By filling the battery cells with BDMAEE foaming material, heat transfer can be effectively reduced.
Case protection: Adding a layer of BDMAEE foaming material inside the shell can improve the impact resistance and fire resistance of the entire battery pack.

5.2 BDMAEE enhances the effect of fireproof isolation

Experimental data show that battery packs using BDMAEE foaming material show significant advantages in the face of thermal runaway. For example, in simulated collision tests, a battery pack equipped with a BDMAEE foam layer successfully prevented the spread of the flame, while a severe fire occurred in the control group without the material.

Test items	Using BDMAEE Material	BDMAEE material not used
Flame spread time	>30 minutes	<5 minutes
Temperature peak	120°C	300°C
Smoke production	Traced	mass

It can be seen that BDMAEE foaming material does have outstanding performance in fireproof isolation.

6. Research progress and case analysis at home and abroad

6.1 Current status of domestic research

In recent years, domestic scientific research institutions and enterprises have made significant progress in BDMAEE foaming technology. For example, a well-known battery manufacturer successfully developed a new thermal insulation material by optimizing the BDMAEE formula, with a thermal conductivity of only 0.02 W/(m·K), which is far lower than the industry average.

In addition, a study from Tsinghua University shows that by adjusting the dosage of BDMAEE, the porosity and mechanical strength of foam materials can be accurately controlled, thereby meeting the needs of different application scenarios.

6.2 International Research Trends

In foreign countries, BDMAEE foaming technology has also received widespread attention. A US startup has developed a self-healing insulation using BDMAEE, which automatically restores its insulation properties even after damage. The German research team focuses on exploring the synergistic effects of BDMAEE and other functional additives, striving to further improve the comprehensive performance of the material.

In the future, scientists will continue to delve into the catalytic mechanism of BDMAEE and try to combine it with other advanced materials to develop more high-performance products. At the same time, with the continuous improvement of production processes, the cost of BDMAEE is expected to be further reduced, thereby promoting its widespread application in more fields.
