Market Overview

The global supercapacitor market size was worth 278.95 billion yen in 2024.
Supercapacitors are used as electrical energy storage devices that complement primary and secondary batteries in mobile electronics, such as personal computers, smartphones, and tablets.
Despite having a lower capacity than lithium-ion batteries (which are a typical type of secondary battery), supercapacitors can charge electricity faster, and are less likely to cause thermal runaway, making them safer to operate.
By combining them with batteries, supercapacitors contribute to the safe operation of electronic devices. The supercapacitor market is expected to grow, as supercapacitors are poised to become essential components underlying the growth of current digital devices.

Challenges in the National Support System for Japanese Monozukuri (Manufacturing) for Market Expansion

Since the inception of the market, Japanese manufacturers have developed supercapacitors and continuously improved their product technologies.
Meanwhile, overseas manufacturers have received strengthened support, measures, and funds from the national and local governments working together to advance technology in this field.
To counter these competitive pressures, the Japanese government must promote and fund manufacturers’ initiatives to develop these technologies as a national project.
The government should enhance its support measures by providing opportunities for collaboration and information exchange among companies, including competitors of product developers, as well as companies planning to enter the market. This collaboration and information exchange could lead to future technological development, even among competing companies.
Aligning with the government is important for companies to become global top players in this field. 

Future Outlook

Due to ongoing research and development, as well as increased sales, the global supercapacitor market is expected to reach 310.7 billion yen by 2025.
The market is projected to grow to 462.24 billion yen by 2028 and 633.178 billion yen by 2030. Thus, the market size in 2030 will be 204% larger than in 2025.
By 2030, supercapacitors will have expanded their applications beyond automotive components to include rapidly growing AI applications. Demand is expected to increase due to growing attention on supercapacitors as a solution to energy efficiency issues, as well as battery-related environmental and technological concerns.
