전기차 상변화 물질 시장 규모, 점유율 및 성장 예측(2026-2031년)

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.
