Phase change materials (PCMs) are substances that can absorb or release large amounts of heat when they change from one physical state to another. This makes them useful in a variety of applications, including energy storage and thermal management.
Phase change materials can be utilised in the context of electric cars (EVs) to enhance battery performance and increase the vehicle’s range. Particularly, PCMs can aid in controlling the battery pack’s temperature, which is crucial for preserving its effectiveness and longevity.
A battery produces heat as it is charged or discharged, and this heat might eventually cause the battery to degenerate. The temperature of the battery can be controlled within a specific range by utilising phase change materials to absorb and release this heat, extending the battery’s lifespan.
Furthermore, phase change materials can be employed to enhance the efficiency of EV rapid charging stations. The charging station can be cooled more effectively and the charging time can be decreased, as well as the system’s overall efficiency, by employing PCMs to store extra heat produced during the charging process.
Phase shift materials could be a key component in the creation of more dependable and effective electric cars.
Global EV phase change materials market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
This is to inform you that a building materials manufacturer has utilised HEATORAGE, a resin heat storage material created by Sumitomo Chemical Co., Ltd., in a sheet-type phase change material (PCM) launch. Any product using HEATORAGE is being sold and used in society for the first time at this time.
HEATORAGE is a resin that can be easily moulded using extrusion, injection, and spinning. It uses phase change* to absorb or release latent heat at a specified temperature range between 20°C and 50°C.
HEATORAGE® does not need to be placed and sealed in containers (such as aluminium packs, plastic containers, or capsules) to prevent leakage at the time of liquefaction after heat storage, as would otherwise be the case with conventional low molecular heat storage materials.
This is because its solid form can be maintained within a specific storage temperature range even after being moulded. This gives processing options, such as cutting and nailing moulded heat storage materials, a great degree of flexibility.
One of the weaknesses of Japanese homes is the inability of the roofs to effectively insulate against heat in the summer. Sumitomo Chemical and the manufacturer of building materials have looked into using HEATORAGE as a material to address this issue.
Because of this, the businesses have found that sandwiching PCM between plastic foam insulation materials (roofing materials) can significantly reduce indoor heat penetration during the summer’s peak solar radiation, lower the cooling burden on air conditioners, and conserve energy all day long.
