Environmentally Friendly Thermal Management Materials With Excellent Thermal Stability - Long Term Battery Operation: Phase Change Materials For Batteries

Product Introduction:

• In a battery pack, phase change materials are usually in close contact with or integrated with the cell, forming a thermal management system that works together.
• By arranging the phase change material reasonably around or inside the battery, the temperature distribution of each cell in the battery pack can be effectively balanced, the occurrence of local overheating or undercooling phenomenon can be reduced, and the overall performance and consistency of the battery pack can be improved.

Nature of the product:

-- Physical properties
1. Density

• The density is moderate, neither due to excessive density increases the weight burden of the battery system, nor due to too small density leads to too large material volume difficult to apply, different types of phase change materials have different densities, can be selected according to specific needs.

2. Volume change

• A certain volume change occurs during the phase change process, and the phase change material can prevent material leakage or damage to the battery structure due to volume expansion to the greatest extent.

3. Liquidity

• For liquid or phase change materials with certain fluidity, its fluidity will affect the transfer and distribution of heat, and good fluidity will help to improve the uniformity of thermal management.

-- Chemical properties:
1. Chemical stability

• It has good chemical stability and is not easy to chemically react with other substances in the working environment of the battery, so as to ensure its stable performance during long-term use and will not have a negative impact on battery performance.

2. Corrosiveness

• Generally non-corrosive or minimally corrosive, will not cause corrosion to the battery electrode, shell and other components, to ensure the integrity and safety of the battery system.

Common application cases of the product:
1. Aviation battery system

• In aerospace applications, battery reliability and safety are of Paramount importance.
• Phase change materials can be used for thermal management of aviation batteries to ensure that the battery can maintain stable performance in complex flight environments and extreme conditions such as high altitude and low temperature, and provide reliable power support for avionics equipment.

2. Satellite batteries

• Satellites are faced with harsh temperature environment in space, and the temperature control of batteries is very important for the normal operation and life of satellites.
• Phase change materials can help the satellite battery adapt to the temperature change of the space environment, maintain the normal working temperature of the battery, and ensure the energy supply of the satellite and the stability of the system.

3. Batteries for military communication equipment

• Military communication equipment requires very high battery performance and reliability, and phase change materials can be used for battery thermal management of these equipment to ensure that the battery can work stably in a variety of harsh battlefield environments, and provide reliable power guarantee for military communications.

Packaging and storage:
1. Packing method

• 25 kg/bag

2. Storage method

• Dry, cool and ventilated place without sharp objects.
