On December 2, the "300 ton/year high quality organic system activated carbon continuous preparation technology and application" scientific and technological achievements appraisal meeting was held in Beijing on December 2, 2018.
Ministry of industry and electronic information foundation, China electrotechnical society, the relevant person in charge of China's super capacitor industry alliance etc, academy of military sciences chemical defense research institute, tsinghua university, Beijing university, zhejiang university, Chinese academy of sciences institute of electrical and related application enterprise units of the experts and scholars, guangxi beihai government representatives attended the assessments of scientific and technological achievements.The appraisal committee, with academician Yang yusheng as the chairman, unanimously agreed that this achievement fills the gap of high quality organic super capacitor activated carbon in China and reaches the international advanced level.
According to guangxi beihai industrial park, the project was developed by guangxi beihai herong activated carbon co., ltd. and beihai xingshi carbon materials co., ltd. over 10 years.At present, the project has produced 110 tons of products, after testing and user experience, its capacitance comprehensive performance is better than foreign products, the stability of batch supply is more fully recognized by customers.Pei xiangjing, vice President and secretary general of China electrotechnical society, gao bo, secretary general of China super capacitor industry alliance, and zhang yonglin, general manager of beihai xingshi carbon material technology co., LTD., the achievement unit, made speeches at the meeting respectively.
Supercapacitors, as high-efficiency energy storage devices, are widely used in national defense and military industry, rail transit, urban bus, lifting machinery potential energy recovery, power generation and smart grid, consumer electronics and other important fields and links.However, high quality organic super capacitor activated carbon is the only active material that provides energy in the most widely used double-layer super capacitor with the largest sales volume in the market at present. It is also the core material in the super capacitor.The advantages of high energy density, high power density and long service life can be realized only when the requirements of large specific surface area, reasonable pore size distribution, high purity and high bulk density are met.The above high quality requirements make it difficult to overcome technical problems. Meanwhile, the requirement of product uniformity and low cost also requires the establishment of large and continuous production lines.
Under the leadership of chairman zhang yonglin, guangxi beihai xingshi carbon material science and technology co., ltd. has developed the activated carbon technology with a specific surface area of 1900m2/g by three-step method (pre-activation -- activation -- pore size adjustment) after 10 years of groping and studying with high-quality coconut shells from asean.Formed a unique step impurity removal process, so that the content of oxygen and iron impurity content are less than 20PPm;Based on the understanding of the influence of surface layer characteristics on conductance, a new surface treatment technology was developed to realize the product's low resistivity which is twice as low as that of foreign products.At the same time, the largest activation equipment of the same technology has been developed to realize the recycling of process exhaust gas, and a continuous production line of 300 tons/year high quality organic super capacitor activated carbon has been built, which is characterized by green, environmental protection and safety.
At present, the project has produced 110 tons of products, after testing and user experience, its capacitance comprehensive performance is better than foreign products, the stability of batch supply is more fully recognized by customers.Supercapacitors, as high-efficiency energy storage devices, can be applied in many fields such as national defense and military industry, rail transit, power generation and smart grid, and consumer electronics.However, high quality organic super capacitor activated carbon is the only active material that provides energy in the most widely used double-layer super capacitor with the largest sales volume in the market at present. It is also the core material in the super capacitor.In addition, some experts pointed out that the large-scale localized production of xingshi super capacitor activated carbon in guangxi beihai industrial park will greatly contribute to the development of China's super capacitors and drive the development of guangxi's super capacitor industry.
