Humid environment will cause corrosion and insulation risk to the battery performance and electrical components, so the container should have good sealing, the recommended protection level is not less than IP54 (indoor) or IP65 (outdoor). Waterproof seals, moisture-proof coatings and dehumidification modules are used to effectively control the internal humidity and ensure the long-term stable operation of the system.
For macro packaging, ensuring the corrosion resistance of packaging materials in the TES system has become its main problem, because it is not only related to the safety of food in the transportation process but also related to the long-term use and complete function of the entire energy storage system, .
The oxide layer formed on the metal surface protects the base metal and prevents the corrosion process. The final results show that stainless steel has good corrosion resistance to the PCM of the above metal salt hydrates.
Which PCM is most corrosion-resistant?
Among them, stainless steel is the most corrosion-resistant metal among all studied PCMs, which has a low corrosion rate and minimal mass loss. Therefore, it is recommended to use stainless steel as the content material when using the PCM used in this experiment. Table 6 shows the performance and price of the PCM used in the experiment. Fig. 6.
Can organic phase change materials corrode packaging containers?
When organic phase change materials are used as energy storage media, corrosion of packaging containers will also occur. Kahwaji et al. performed corrosion tests on six organic phase change materials, and their selected material formulations are shown in Table 9.
Can PCM be used as energy storage media?
When using PCM as energy storage media, the corrosion problem is also extremely important, because different PCM for different packaging materials corrosion is also very different. PCM will inevitably cause varying degrees of corrosion to both metals and polymers, damaging the storage containers to varying degrees and reducing their life.
Stainless steel 304 and stainless steel 316 are resistant to all the tested PCM. Aluminium should be avoided as an SP21E container. Copper is corroded by both fatty acid eutectics. 1. Introduction Energy policies are nowadays focused on using solar energy and reusing the waste heat of the industry to use them as a primary energy source.
