Chinese.Supercapacitors also known as electrochemical capacitors (EC), gold capacitors, and Farad capacitors, include double-layer capacitors (electrostatic double-layer capacitors) and pseudo capacitors (electrochemical pseudocapacitors), which store energy through polarizing electrolytes. They are electrochemical components, but their energy storage process doesn’t involve chemical reactions. This reversible energy storage process allows supercapacitors to be charged and discharged hundreds of thousands of times.
As a novel energy storage device, supercapacitors possess significant features and advantages, including Farad-level ultra-large capacity. They have the potential to replace traditional batteries in certain fields. In today’s era of energy conservation and environmental protection, their applications are gaining increasing attention worldwide. Supercapacitors exhibit characteristics such as low resistance, an extended lifespan, safety and reliability, high energy storage capacity, and rapid charging.
They can also achieve ultra-large capacitances ranging from several hundred to even tens of thousands of Farads, enabling the release of hundreds to thousands of amperes of current instantly. They remain unaffected even by high current discharges or short circuits. Additionally, they have short charging times, completing within seconds, making them ideal for high-power secondary power sources. They can be used in extremely harsh environments, including extremely low temperatures, with no environmental pollution. Their features include safety, reliability, wide applicability, environmental friendliness, and easy maintenance. They serve as groundbreaking components for improving and resolving electric power and propulsion applications. These characteristics provide electrochemical capacitors with broad market prospects in power applications such as electric vehicles, communications, consumer electronics, entertainment electronics, signal monitoring, and more.
In 2014, the domestic market scale for supercapacitors was 4.84 billion yuan, a 56.1% increase compared to 2013. By 2015, the domestic supercapacitor market reached 6.65 billion yuan. The compound annual growth rate from 2012 to 2015 exceeded 40%. Supercapacitors for transportation and logistics will be the most critical driving force for the industry’s rapid development. By 2018, supercapacitors for transportation and logistics are projected to account for more than half of the entire supercapacitor market share.
According to the “China Supercapacitor Market Status Analysis and Investment Prospect Research Report for the period 2017 to 2022” released by BOST Data, in 2015, China’s supercapacitor market was 6.65 billion yuan. The market size for transportation and logistics supercapacitors was around 2.54 billion yuan, for industrial supercapacitors around 2.05 billion yuan, for new energy supercapacitors around 1.45 billion yuan, and for other applications, such as equipment, around 610 million yuan. This data provides insights into the consumer market structure of supercapacitors in China.
