Super capacitors, also known as ultracapacitors or electrochemical capacitors, are energy storage devices that have gained significant attention due to their unique characteristics, having below pros and cons:

Pros:

1）High power density: Supercapacitors can deliver high power output, making them suitable for applications requiring quick charging and discharging, such as regenerative braking in electric vehicles.

2）Long cycle life: Unlike batteries, supercapacitors have a longer lifespan, with the ability to withstand hundreds of thousands to millions of charge-discharge cycles without significant degradation.

3）Rapid charging: Supercapacitors can be charged and discharged much faster compared to traditional batteries, reducing the charging time for devices or systems.

4）Wide operating temperature range: Supercapacitors can operate efficiently in extreme temperatures, making them suitable for various environments and applications.

5）Environmental friendliness: Supercapacitors do not contain harmful chemicals, making them less detrimental to the environment compared to certain battery chemistries.

Cons:

1）Low energy density: Supercapacitors have relatively lower energy storage capacity compared to batteries. This limits their use in applications requiring long-term energy storage or high energy density.

2）Voltage limitations: Supercapacitors have lower maximum voltage limits compared to batteries, which may restrict their use in applications requiring high voltage operation.

3）Cost: Supercapacitors are currently more expensive compared to traditional battery technologies, limiting their widespread adoption in certain industries.

4）Leakage current: Supercapacitors have inherent self-discharge rates, leading to a small leakage current over time, which reduces their overall efficiency and energy retention.

5）Size and weight: Supercapacitors are generally larger and heavier compared to traditional batteries, making them less suitable for compact or lightweight applications.

The Chinese market for supercapacitors:

China is the largest consumer and manufacturer of supercapacitors globally, with the market witnessing significant growth in recent years. The adoption of supercapacitors is gaining traction in various industries, including automotive, transportation, consumer electronics, renewable energy, and industrial sectors in China.

Factors driving the growth of the Chinese supercapacitor market include government support for electric vehicles, increasing demand for energy storage solutions, and the country's commitment to renewable energy sources. Additionally, the growing popularity of smartphones, wearables, and other portable electronic devices is driving the demand for small-sized and high-performance supercapacitors.

Chinese companies are actively engaged in the research, development, and production of supercapacitors.

HONGADA Capacitors, as the leading manufacturer in China, with ISO9001 qualification, invests in advanced production technologies to improve the performance and reduce the cost of supercapacitors.

Panasonic discontinued some items of super capacitors, like ES5R5224Z-, ES5R5224Z-, ES5R5474Z-, ES5R5474Z-, ES5R5105Z-, etc.

HONGDA Capacitors’ HCE series, can be good replacement, various type available H type, V type, C type, fast delivery.
