Supercapacitor technology breaks through bottleneck energy density than shoulder lithium battery

Recently, supercapacitor technology has achieved breakthroughs. According to the latest reports from foreign media, 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 lithium battery. -120Wh/kg. According to domestic media reports, in January this year, Professor Xia Hui of the Polytechnic Institute of Nanjing Institute of Technology discovered a new material that can increase the capacitance of supercapacitors by 5-10 times. The research results are published worldwide. Top journal "Advanced Materials". The capacity of the supercapacitor using this material can be increased by 5-10 times, and the endurance capacity is extended by 5-10 times. Researchers say the new materials can be used in electric buses after two or three years.

The industry believes that the current commercial supercapacitors mostly use activated carbon material electrodes, energy storage rate is limited, high-end supercapacitors only 1/12 of lithium batteries per kilogram capacity, which limits the wide application of supercapacitors. With the technological breakthrough of capacitive materials, the supercapacitor market is expected to usher in explosive growth. The agency predicts that by 2018, China's supercapacitor market will reach 7.1 billion yuan, and in 2020 it will reach 11 billion yuan.
