全球電動車相變材料市場規模、市場佔有率及成長預測（2026-2031年）

預計到 2026 年，全球電動車相變材料市場規模將達到 9,000 萬美元，到 2031 年將達到 2.85 億美元，預測期內複合年成長率為 25.9%。

全球電動車相變材料市場正快速崛起，成為電動車溫度控管的關鍵技術。相變材料在物理狀態改變時會儲存潛熱，進而吸收熱量。在電動車電池中，相變材料可放置在電芯、模組或熱界面周圍，以吸收短時快速的熱浪並降低溫差。與泵浦和製冷迴路不同，相變材料在相變過程中不消耗能量。這在間歇性而非持續性熱浪的情況下具有顯著優勢。

推動市場發展的因素包括電池能量密度提升、快速充電、持續輸出增強以及電池組尺寸縮小。這些趨勢導致局部發熱和溫度梯度增加。相變材料（PCM）技術可能會延遲主動冷卻系統全面運作的時間。然而，從商業性角度來看，人們對混合架構的興趣日益濃厚，而非僅使用PCM的系統。將PCM與液冷板、散熱片、石墨結構或熱管結合，既能解決傳統PCM導熱係數相對較低的問題，又能保持其緩衝瞬態熱量的能力。

亞太地區是重要的區域市場，這得益於其集中的電動車生產、鋰離子電池製造和溫度控管工程技術。中國是銷售量最大的市場，而日本和韓國則在先進材料、電池技術和電子領域擁有豐富的專業知識。印度也在以相變材料（PCM）為基礎的電池溫度控管相關研究和工程領域日益嶄露頭角。

市場促進因素

電池能量密度的提升使得熱緩衝技術更有價值。

• 電動車電池的設計越來越注重快速充電、高持續功率輸出和緊湊封裝。這些要求導致在高倍率充放電過程中產生更多熱量。此外，電池單體之間以及電池模組內部也可能出現更大的溫差。
• 相變材料（PCM）能夠吸收短時熱峰值，從而延緩需要強力主動冷卻的時間。這減輕了冷卻系統的負擔，同時也實現了更穩定的電池溫度維持。隨著製造商致力於提升電池性能並降低輔助能耗，這種方法的價值日益凸顯。
• 當熱峰值持續時間較短時，這項技術尤其有效。相變材料（PCM）能夠在高負載條件下吸收熱量，然後透過適當的溫度控管路徑釋放或轉移累積的熱量。

混合冷卻架構提高了實用性

• 結合相變材料（PCM，即溫度控制模組）和液冷技術的混合冷卻系統正成為重要的研發領域。 PCM負責吸收潛熱，而液冷則提供持續的散熱。這種組合克服了被動式PCM系統的一個主要限制：導熱係數相對較低的材料難以有效傳熱。
• 將相變材料（PCM）與液態冷板、散熱片、石墨結構和熱管整合，可改善溫度控制。此外，在中等熱負荷下，主動冷卻系統也能以更溫和的方式運作。這使得這種混合配置比僅使用PCM的系統更適合高功率電動車應用。
• 此外，研究表明，將相變材料與銅翅片或其他導熱結構結合使用具有巨大潛力。這種結構既能提高熱擴散率，又能維持相變材料的熱緩衝能力。

材料科學正在超越傳統的石蠟材料。

• 有機石蠟基相變材料因其化學穩定性和可預測的相變行為而受到廣泛研究。然而，材料研發正不斷拓展，涵蓋生物基材料、鹽水合物、共晶體係以及具有更高導熱係數的複合材料。
• 複合相變材料尤其重要，因為它們解決了傳統材料固有的導熱係數低的問題。膨脹石墨、碳結構、金屬泡沫和其他導熱材料可以改善相變材料的熱流入和熱流出。
• 這項進展拓寬了該材料在汽車領域的潛在應用範圍。同時，也為能夠提供兼具合適相變溫度、潛熱容量、導熱性、結構穩定性和長期循環性能等特性的材料的供應商創造了新的商機。

市場限制因素

重量和包裝限制

• 相變材料（PCM）會增加電池組的材料品質並佔據空間。這些特性對電動車製造商來說可能是一個挑戰，因為他們已經致力於減輕車輛重量並最大限度地提高電池能量密度。
• 此外，這種材料必須有效地圍繞在電池和組件周圍，且不得干擾電池組的其他組件。封裝和結構整合可能會增加額外的設計要求。因此，製造商必須評估散熱優勢是否足以抵消額外的材料或封裝要求。

再凝固和散熱要求

• 被動式相變材料系統在相變過程中吸收熱量，但最終必須移除累積的熱能才能使材料恢復到原始狀態。重複的熔化和重凝固會使熱力學和力學設計變得複雜。
• 這項限制使得相變材料不太可能完全取代主流高功率電動車中的主動冷卻系統。相反，這項技術更有可能作為液冷或其他主動冷卻系統的補充。實用化將取決於能否在熱性能、系統複雜性、材料成本和封裝要求之間取得適當的平衡。

熱導率限制

• 許多傳統相變材料的導熱係數相對較低。這會減緩熱量在材料內部和外部的流動。雖然可以透過添加提高導熱係數的添加劑或結構組件來解決此限制，但這可能會增加材料成本和製造流程的複雜性。
• 因此，複合材料的開發和改進的相變材料配方與該技術的商業性可行性密切相關。

The global EV phase-change materials market is estimated at USD 90.0 million in 2026 and is projected to reach USD 285.0 million by 2031, at a CAGR of 25.9% during the forecast period.

The global EV phase-change materials market is emerging as an important technology area within electric vehicle thermal management. Phase-change materials absorb heat through latent-energy storage as they transition between physical states. In EV batteries, they can be positioned around cells, modules, or thermal interfaces to absorb short-duration heat spikes and reduce temperature differences. Unlike pumps and refrigeration loops, PCMs do not consume electrical power during the phase transition. This creates value where thermal peaks are intermittent rather than continuous.

The market is being supported by higher battery power density, faster charging, higher continuous power, and increasingly compact battery-pack designs. These trends increase localized heat generation and temperature gradients. PCM technology can delay the point at which active cooling needs to operate at full capacity. However, the commercial direction is increasingly focused on hybrid architectures rather than PCM-only systems. Combining PCM with liquid cold plates, fins, graphite structures, or heat pipes helps address the relatively low thermal conductivity of conventional PCMs while retaining their ability to buffer transient heat.

Asia Pacific is the leading regional market due to its concentration of electric vehicle production, lithium-ion battery manufacturing, and thermal-management engineering. China represents the largest volume market, while Japan and South Korea contribute advanced materials, battery technologies, and electronics expertise. India is also becoming increasingly visible in PCM-based battery thermal-management research and engineering.

Market Drivers

Higher Battery Power Density Increases the Value of Thermal Buffering

• EV batteries are increasingly designed for faster charging, higher continuous power, and compact packaging. These requirements increase heat generation during high-rate charging and discharging. They can also create larger temperature gradients between cells and within battery modules.
• Phase-change materials can absorb short-duration thermal peaks and delay the need for intensive active cooling. This can reduce the burden on cooling systems while helping maintain more consistent battery temperatures. The value of this approach becomes more significant as manufacturers seek to improve battery performance while limiting auxiliary energy consumption.
• The technology is particularly relevant when thermal peaks are temporary. PCM can absorb heat during a high-load event and later release or transfer the stored heat through a suitable thermal-management pathway.

Hybrid Cooling Architectures Improve Commercial Relevance

• Hybrid PCM-liquid cooling systems are becoming a key development area. PCM provides latent-heat absorption, while liquid cooling provides sustained heat removal. This combination addresses a major limitation of passive PCM systems, which is the difficulty of transferring heat through materials with relatively low thermal conductivity.
• The integration of PCM with liquid cold plates, fins, graphite structures, and heat pipes can improve temperature control. It can also allow active cooling systems to operate less aggressively during moderate thermal loads. This makes hybrid configurations more suitable for high-power EV applications than PCM-only systems.
• Research has also demonstrated the potential of combining PCM with copper fins and other conductive structures. Such configurations improve heat spreading while maintaining the thermal-buffering capability of the PCM.

Material Engineering Is Expanding Beyond Conventional Paraffin

• Organic paraffin-based PCMs remain widely studied because of their chemical stability and predictable phase-change behavior. However, material development is expanding into bio-based materials, salt hydrates, eutectic systems, and conductivity-enhanced composites.
• Composite PCMs are particularly important because they address the low thermal conductivity of conventional materials. Expanded graphite, carbon structures, metal foams, and other conductive materials can improve heat transfer into and out of the PCM.
• This development is expanding the range of potential automotive applications. It also creates opportunities for suppliers that can combine suitable transition temperatures, latent heat capacity, conductivity, structural stability, and long-term cycling performance.

Market Restraints

Weight and Packaging Constraints

• PCM adds material mass and occupies space within the battery pack. These characteristics can create challenges for EV manufacturers that are already seeking to reduce vehicle weight and maximize battery energy density.
• The material must also be positioned effectively around cells or modules without interfering with other pack components. Encapsulation and structural integration can add further design requirements. Manufacturers therefore need to evaluate whether the thermal benefits justify the additional material and packaging requirements.

Re-Solidification and Heat Rejection Requirements

• Passive PCM systems absorb heat during phase transition, but the stored thermal energy must eventually be removed to allow the material to return to its original state. Repeated melting and re-solidification can complicate thermal and mechanical design.
• This limitation reduces the likelihood that PCM will completely replace active cooling in mainstream high-power EVs. Instead, the technology is more likely to complement liquid cooling and other active systems. Commercial adoption will depend on achieving an appropriate balance between thermal performance, system complexity, material cost, and packaging requirements.

Thermal Conductivity Limitations

• Many conventional PCMs have relatively low thermal conductivity. This can slow the transfer of heat into and out of the material. Conductivity-enhancing additives and structural components can address this limitation, but they can also increase material cost and manufacturing complexity.
• As a result, the development of composite and enhanced PCM formulations is closely connected to the commercial viability of the technology.

Technology and Segment Insights

Material Type

• Organic PCM represents the largest material segment. It generates approximately USD 46.8 million in 2026 and is projected to grow at around 23.5% CAGR through 2031. Paraffin-based materials remain prominent because of their stable phase-change behavior and availability across relevant automotive temperature ranges. Future adoption will depend on improvements in thermal conductivity and flame resistance.
• Composite and conductivity-enhanced PCM represents another major technology segment. It accounts for approximately 34% of the market in 2026 and is projected to grow at around 29.5% CAGR through 2031. Graphite, fins, and other conductive structures improve heat transfer while retaining the latent-heat storage capability.
• Inorganic PCMs can provide higher latent heat density and different phase-transition characteristics. However, corrosion, phase separation, and supercooling can complicate automotive applications. Eutectic systems offer more precise transition-temperature control and may gain relevance in specialized battery-pack designs.

Application

• Battery-pack thermal management represents the dominant application. It accounts for approximately 81% of global revenue in 2026 and is projected to approach USD 240 million by 2031. PCM can be positioned around cells, modules, and thermal spreaders to control temperature rise and improve thermal uniformity.
• Power electronics represent a smaller application area. However, increasing thermal density in compact inverters and chargers can create additional opportunities. Phase-change materials can also be used in other EV thermal applications where transient heat loads need to be controlled.

Vehicle Type

• Passenger battery electric vehicles account for approximately 72% of the market in 2026 and are projected to grow at roughly 24.5% CAGR through 2031. Adoption is concentrated in high-performance, premium, and advanced battery-pack designs where improved thermal uniformity and reduced peak thermal loads can justify additional material costs.
• Commercial electric vehicles represent approximately 15% of the market in 2026 and are projected to reach about USD 50 million by 2031. Longer operating cycles, higher battery throughput, and repeated fast charging create stronger requirements for thermal buffering. This segment is expected to grow at approximately 30.0% CAGR through 2031.
• Plug-in hybrid electric vehicles and electric two-wheelers and three-wheelers represent additional application opportunities. Their requirements vary according to battery capacity, operating conditions, charging rates, and thermal-management architecture.

Form

• Bulk or molded PCM provides a direct approach for integrating thermal-buffering material into battery structures. Encapsulated PCM can improve containment and simplify integration. Composite sheets and pads offer another approach where controlled thickness, thermal conductivity, and installation flexibility are required.
• The selection of form depends on battery-pack architecture, available space, required thermal performance, mechanical integration, and manufacturing processes.

Geography

• Asia Pacific represents approximately 58% of the global EV phase-change materials market in 2026. The region generates approximately USD 52.2 million in revenue and is projected to grow at around 26.8% CAGR through 2031.
• China leads because of its large EV and battery-manufacturing base. Japan and South Korea contribute advanced materials, electronics, and battery engineering capabilities. India is emerging as a research and pilot market alongside rapid EV production growth.
• North America and Europe provide additional opportunities through EV production, battery manufacturing, and advanced thermal-management development. South America and the Middle East and Africa represent smaller markets with developing EV adoption and related thermal-management requirements.

KGaA, Parker LORD, Boyd Corporation, Croda International, Honeywell International, Climator Sweden, Rubitherm Technologies, Pluss Advanced Technologies, PureTemp, PCM Products, Outlast Technologies, Phase Change Energy Solutions, SGL Carbon, Graphite India, and Laird Thermal Systems.
• Competition is centered on phase-transition temperature, latent heat capacity, thermal conductivity, flammability, cycle stability, packaging compatibility, and integration characteristics. Automotive customers require predictable material behavior over extended service lives. Suppliers that can provide encapsulated or structurally stable composite PCM can therefore address important integration requirements.
• Product development is increasingly focused on hybrid solutions. PCM combined with liquid cooling can provide transient thermal buffering while allowing active cooling to manage stored heat. Conductivity-enhanced PCM is another important area because it improves heat transfer without eliminating the latent-heat function.
• Research is also expanding beyond conventional paraffin. Bio-based composite PCM, inorganic materials, eutectic systems, and graphite-enhanced formulations are being evaluated for EV battery applications. These developments create opportunities for differentiated material solutions.
• Asia Pacific is expected to remain the primary development and commercialization center through 2031. Its concentration of EV manufacturers, battery producers, materials suppliers, and thermal-management engineering capabilities supports close integration between PCM developers and vehicle or battery manufacturers.
• The market is also moving toward broader automotive applications. Henkel's phase-change thermal interface products demonstrate that the technology can extend beyond battery thermal management into EV power-conversion applications. Continued improvements in material performance and integration could expand the addressable market across additional thermal loads.

Conclusion

• The global EV phase-change materials market is forecast to expand from USD 90.0 million in 2026 to USD 285.0 million by 2031 at a CAGR of 25.9%. Rising battery power density, faster charging, compact battery packaging, and the need for improved thermal uniformity are supporting demand. Battery-pack thermal management will remain the primary application, while commercial EVs are expected to record particularly strong growth. Organic PCMs currently lead the material landscape, but composite and conductivity-enhanced formulations are gaining importance. The market's commercial development will depend on overcoming weight, packaging, conductivity, and heat-rejection constraints. Hybrid PCM-liquid cooling architectures are therefore likely to remain central to the technology's adoption across advanced EV platforms.
