New breakthroughs in super capacitor technology, large-scale applications will start

According to the latest media reports, researchers from two universities in the UK have discovered a new type of supercapacitor material that can not only shorten the charging time to less than 10 minutes, but also increase the energy density to 180Wh/kg, which is higher than the current 100- commonly used lithium battery. 120Wh/kg. In January of this year, Professor Xia Hui's group from the Gretel Institute of Nanotechnology at Nanjing University of Science and Technology also discovered a new material that can increase the capacitance of supercapacitors by 5-10 times.

With its large capacity, high power, long life, low cost, and environmental friendliness, supercapacitors can partially or completely replace traditional chemical batteries, and have more extensive uses than traditional chemical batteries. With the continuous development of technology, it has promoted its application range from the initial electronic equipment field to the power field and energy storage field.

My country has always been actively promoting the development of supercapacitors. In 2006 and 2007, the technical emphasis on the development of supercapacitors was emphasized. Afterwards, a policy to subsidize the application of supercapacitors was introduced, and in May 2017, my country introduced The first supercapacitor basic standard and the first industry standard in terms of materials. Although my country’s supercapacitor market started late, my country’s supercapacitor industry has developed rapidly in recent years. In 2014, the domestic supercapacitor market was 4.84 billion yuan, an increase of 56.1% compared to 2013. In 2015, the domestic supercapacitor market reached 6.65 billion yuan. The demand for supercapacitors in the Chinese market reaches 12.1% of the global market. Research institutions predict that the market size of my country's supercapacitor industry will increase to 7.1 billion yuan by 2018, and will reach about 11 billion yuan in 2020. On the other hand, supercapacitors are not only included in the national special support key projects, but also selected as "Key Products of Strategic Emerging Industries."

Supercapacitors have a wide range of applications and can effectively achieve the purpose of energy saving and environmental protection. With the increase of national policy support and the continuous upgrading of technology, large-scale applications will start quickly, and the sector has huge room for imagination.
