The growth in the forecast period can be attributed to increasing penetration of ev and hev architectures, rising preference for high power auxiliary storage, growing shift toward hybrid capacitor platforms, advancements in electrode and electrolyte materials, expansion of automotive electrification policies. Major trends in the forecast period include growing use of ultracapacitors in ev powertrains, increasing adoption in start stop systems, rising integration in regenerative braking applications, enhanced demand for high power density storage, shift toward hybrid capacitor technologies.

The growing demand for electric vehicles is anticipated to drive the expansion of the automotive ultracapacitor market in the coming years. Electric vehicles (EVs) are powered by electricity instead of traditional internal combustion engines that use gasoline or diesel. In EVs, automotive ultracapacitors enhance performance, extend battery life, and serve as backup power sources in emergencies. For example, in April 2024, the International Energy Agency, a France-based autonomous intergovernmental organization, reported that nearly 14 million new electric cars were registered globally in 2023, bringing the total to 40 million on the roads. Electric vehicles accounted for approximately 18% of all car sales, up from 14% in 2022. In China alone, new electric car registrations reached 8.1 million, representing a 35% increase from the previous year. As a result, the rising demand for electric vehicles is fueling the growth of the automotive ultracapacitor market.

Key players in the automotive ultracapacitor market are concentrating on developing innovative products to strengthen their market position. High-performance supercapacitors, characterized by high specific capacitance and power density, are among the innovative products aimed at providing reliable services. In March 2023, KEMET Corporation introduced the FMU Series, a high-performance supercapacitor designed for vehicle electronics, featuring an industry-leading operational temperature range and suitable for applications such as advanced driver assistance systems (ADAS) and central gateway electronic control units (ECUs). This focus on innovation is a strategic move to meet customer needs and enhance market competitiveness.

An automobile ultracapacitor, also known as a supercapacitor or electrochemical capacitor, is an electrical energy storage device that utilizes electrostatic charge separation to store and release energy rapidly. These ultracapacitors are commonly employed in automotive systems to provide high-power acceleration assistance during braking, thereby enhancing overall vehicle reliability and efficiency.

The main types of automotive ultracapacitors include double-layered capacitors, pseudo-capacitors, and hybrid capacitors. A double-layered capacitor, also known as an electric double-layer capacitor (EDLC) or supercapacitor, is a device for storing electricity that leverages the double-layer capacitance phenomena. Automotive ultracapacitors are utilized in both passenger vehicles and commercial vehicles, and they are distributed through various channels, including OEM (original equipment manufacturer) and the aftermarket. These ultracapacitors find applications in various automotive systems such as start-stop operations, regenerative braking systems, and more.Western Europe was the largest region in the automotive ultracapacitor market in 2025.
