Super capacitors have super prospects
Supercapacitors can be widely used in different application scenarios such as auxiliary peak power, backup power, storage and regenerative energy, and alternative power supply. They have very broad development in industrial control, wind power generation, transportation, intelligent three-meter, electric tools, military and other fields. The outlook, especially in some application scenarios, has a very large performance advantage. According to the US Energy Administration, the market capacity of supercapacitors has increased from $4 billion in 2007 to $12 billion in 2013, and the supercapacitors in the Chinese market reached 1.92 billion yuan in 2013. Once the car and other applications are opened, the market will usher in a rapid outbreak.
In the field of new energy, solar energy, wind energy and other energy sources have temporal heterogeneity, which varies greatly in day and night and different seasons. Supercapacitors have advantages such as fast charging, long life, high reliability, and high current resistance. It can be widely used in solar energy, wind power generation and other fields.
When the solar energy and wind energy output are unstable, the supercapacitor is used as a buffer to store excess energy, and when the power output is insufficient, the stored energy in the supercapacitor is released in a short time.
At the same time, in the collection of new energy, various types of mechanical control systems are needed. In the past, the energy of such systems was provided by batteries. Due to the intermittent nature and high instantaneous intensity, the battery life was greatly reduced. Due to its fast charge and discharge and long life, supercapacitors are especially suitable for this application scenario, and can reduce the labor and maintenance costs caused by frequent battery replacement.
Based on the phenomenal growth performance of China's consumer electronics in recent years, it is expected that in the next few years, China's button-type supercapacitors are expected to maintain an average growth rate of more than 30%, and winding and large supercapacitors are likely to maintain an average growth rate of more than 50%. Therefore, we give the super capacitor industry a “optimistic†investment rating.
At present, there are more than 50 manufacturers engaged in the research and development of large-capacity supercapacitors in China, but there are less than 20 manufacturers capable of mass production and achieving practical level. Among the listed companies, we mainly recommend the target: Tongfeng Electronics, Jianghai, Farah Electronics, and Xinzhou.
