Fast temperature adjustment to maintain the operating temperature of the battery - Materials that optimize the battery thermal management system: Phase change materials for high-conductivity batteries

Product introduction:

• According to their chemical properties, they can be divided into organic phase change materials, inorganic phase change materials and eutectic phase change materials.
• Battery specific phase change materials have the characteristics of high energy storage capacity and long-term thermal stability, wide temperature range, high heat capacity and stability, and strong adaptability, which can better meet the specific needs of battery thermal management

Product advantages:
1. Precise temperature control

• It can absorb or release a lot of heat at a specific phase change temperature, so that the working temperature of the battery remains stable, thereby improving the charging and discharging efficiency and service life of the battery.

2. High energy storage density

• During the phase change process, more heat can be stored and released, and more heat can be absorbed or released under the same volume or mass, effectively regulating the battery temperature, reducing the volume and weight of the thermal management system, and improving the energy density of the battery system.

3. Good thermal stability

• In the process of repeated phase change, the performance is stable, not easy to decompose, deteriorate or decay, to ensure long-term reliable thermal management effect, reduce maintenance costs.

4. Good chemical stability

• Good compatibility with other materials and chemicals in the battery, no chemical reaction, to avoid battery performance degradation or safety risks caused by interaction, to ensure the chemical stability and safety of the battery system.

5. Passive thermal management

• No external power source or complex control system, relying on its own phase change characteristics to automatically adjust the battery temperature, simple structure, low cost, high reliability, reduce battery system energy consumption and complexity.

6. Enhance security

• Effectively prevent the battery from overheating and reduce the risk of thermal runaway, which is crucial to ensure the safety of the battery, especially in high temperature environment or high rate charge and discharge.

Common application cases of the product:
1. Thermal runaway protection

• When an electric vehicle crashes or other failures lead to thermal runaway of the battery, phase change materials can absorb a lot of heat, delay the spread of thermal runaway, buy time for personnel evacuation and safety protection, and improve the safety of electric vehicles.

2. Improve system security

• The application of phase change materials in thermal management of energy storage battery system can reduce the risk of thermal runaway of battery, prevent the thermal runaway of individual battery from causing safety accidents of the entire energy storage power station, and ensure the safe operation of energy storage power station.

3. Laptop batteries

• During the use of the laptop, the battery will heat up due to high load operation.
• The integration of phase change materials into the thermal management system of laptop batteries can effectively control the battery temperature, avoid the deterioration of battery performance and shortened life caused by overheating, and also improve the safety and comfort of users.
