High Latent Heat And Strong Stability - Materials That Significantly Extend Battery Life: 75°C Phase Change Materials Assist Battery Thermal Management

Product Introduction:

• 75℃ battery special phase change material is a material that will undergo phase change at about 75℃, which absorbs heat during the heating process, thus storing a large amount of latent heat, when the temperature is reduced, these heat will be released, using this characteristic to adjust the temperature of the battery, so that the battery operating temperature is kept in the appropriate range, and then improve the performance and safety of the battery.

Product features:
1. Precise temperature control

• Its phase change temperature is set at about 75°C, which can accurately phase change when the battery reaches the temperature, absorb or release a lot of heat, so as to effectively adjust the battery temperature, keep the battery operating temperature in the appropriate range, help to improve the performance and safety of the battery, and extend the cycle life of the battery.

2. Adjustable thermal conductivity

• Although some of the phase change materials themselves may have low thermal conductivity, their thermal conductivity can be improved by adding high thermal conductivity fillers, so as to better meet the needs of rapid heat dissipation or heating of the battery, and further improve the efficiency of thermal management.

3. High energy storage density

• During the phase change process, a large amount of latent heat can be absorbed or released, and only a relatively small volume or mass of phase change materials can effectively adjust the temperature of the battery, which is conducive to realizing the compact design and lightweight of the battery system, and is of great significance for improving the energy density and space utilization of the battery.

4. Passive thermal management

• It can work without external power source or complex control system, and automatically absorbs and releases heat by relying on its own phase change characteristics, reducing the complexity and energy consumption of the system, and improving the reliability and stability of the thermal management system.
• At the same time, it also reduces the maintenance cost of the system, especially for battery applications with high reliability requirements and limited space and energy supply.

Product application scenarios:
1. Battery thermal management system

• During the driving process of electric vehicles, the battery will generate a lot of heat, resulting in a rise in temperature, affecting battery performance and life.
• 75℃ battery special phase change material can be used for battery thermal management system, when the battery temperature reaches about 75℃, the phase change material phase change absorbs heat, so as to effectively reduce the battery temperature, prevent overheating, maintain the battery in the appropriate operating temperature range, improve the safety, stability and service life of the battery.

2. Lithium battery energy storage system

• The lithium battery in the energy storage power station will generate heat accumulation during the charge and discharge cycle, and the phase change material for the 75℃ battery can be used as a key part of thermal management to ensure the stable operation of the lithium battery at a temperature of about 75℃.
• Improve the efficiency and reliability of the entire energy storage system, reduce the battery performance attenuation and safety risks caused by excessive temperature, and ensure the stable power supply and long-term operation of the energy storage power station.

3. Smartphones and tablets

• With the continuous improvement of the performance of electronic products, their internal batteries are easy to heat up during high load operation.
• 75℃ battery special phase change material can be applied to the battery module of these devices, when the battery temperature rises to 75℃, the phase change material automatically adjusts the temperature, prevent the battery from overheating, and ensure the normal operation of the equipment.
• At the same time, it also helps to extend the battery life and improve the user experience.
