Suitable For Electric Vehicle Battery Special Phase Change Material - Adapt To Complex Work And Ensure Battery Life And Safety

Product Introduction:

1. When the operating temperature of the battery rises to the phase change temperature of the phase change material, the phase change material begins to absorb heat, and the transformation from solid to liquid or other phase states occurs. In this process, a large amount of heat is absorbed by the phase change material and stored as latent heat, rather than appearing as a large increase in temperature, preventing further increases in the battery temperature.
2. When the temperature of the battery is reduced due to changes in the external environment or working state, the phase change material will change from liquid or other high-energy state phase back to solid or low-energy state phase, and release the heat stored before, providing additional heat supplement for the battery, so that the battery temperature is maintained within the appropriate working range, and avoid the battery performance due to too low temperature.
3. This heat absorption and release process is reversible, and can be automatically adjusted according to the actual temperature of the battery, without the intervention of external complex control system, to achieve passive management of the battery temperature.

Highlights of the product:
1. Latent heat of phase transition

• The heat absorbed or released during the phase transition process is an important indicator of its energy storage capacity.
• Usually with a high latent heat of phase transition, phase change materials per unit mass or volume can absorb or release a large amount of heat, thereby effectively regulating the battery temperature.

2. Specific heat capacity

• The specific heat capacity is large, and the temperature change is relatively small when absorbing or releasing heat, which helps to maintain the stability of the battery temperature.

3. Thermal conductivity

• Reflecting the parameters of the material's heat conduction capacity, some battery special phase change materials improve the thermal conductivity by adding high thermal conductivity substances and other methods to speed up the heat transfer speed and improve the thermal management efficiency.

4. 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.

5. Good chemical stability

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

Common application scenarios of the product:

-- Electric vehicles
1. Battery thermal management

• The lithium-ion battery of an electric vehicle will generate a lot of heat during the charging and discharging process, and if it cannot dissipate heat in time, it will lead to reduced battery performance, shortened life, and even a safety hazard of thermal runaway. Phase change materials can be used in battery modules.
• When the temperature of the battery rises to the phase change temperature of the phase change materials, the phase change materials absorb heat and phase change occurs, thus effectively reducing the temperature of the battery. When the temperature of the battery is reduced, the phase change material will release heat to maintain the stability of the battery temperature, ensure that the battery works within the appropriate temperature range, and improve the charging and discharging efficiency and service life of the battery.

2. 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.

-- Consumer electronics
1. 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.

2. Smartphone batteries

• The battery temperature of a smartphone also increases when it is used for a long time or charged quickly. Phase change materials can be used for heat dissipation and temperature regulation of smartphone batteries, ensuring that the battery works within a safe temperature range, extending battery life and improving user experience.
