Graphene-based supercapacitors will be mass-produced
On September 28, it was learned from Changzhou Cube Energy Technology Co., Ltd. that the company has made a major breakthrough after several years of research and development of graphene-based supercapacitors . Tested by relevant departments, it has the functions of environmental protection, millions of charge and discharge, non-combustible, non-explosive, low temperature resistance, etc. The series products will be put into mass production.
On September 28th, Kazakhstan’s national adviser, member of parliament, and electrical machinery expert Yakusevich Sergei Irijic made a special trip to Cube to use graphene alkenes at the 2017 World Expo in Kazakhstan next year. Negotiate matters such as supercapacitors . “The slogan of the 2017 World Expo is 'Future Energy', which will showcase the most cutting-edge technologies in the field of renewable energy. The company has achieved remarkable results in the application of graphene energy storage materials, which is consistent with the theme of the Astana Expo. Said Sergey.
The cubic energy company, established three years ago, has been focusing on the development of graphene-based supercapacitors. In August last year, it successfully developed energy-type graphene-based supercapacitor samples.
“After one year of technical improvement, we solved a series of problems in industrial production.†Song Bo, general manager of the company, said that due to the special nature of graphene composite slurry, it is not easy to process into electrode pole pieces. The improvement of the coating process and the non-standard design of the coater have solved the problem that the graphene paste is difficult to be coated. And this key technology has broken the bottleneck of mass production of the entire product. At present, the company has applied for 12 core technology patents for the technical difficulties of graphene-based supercapacitor products, of which 7 have been authorized by the National Patent Office.
According to reports, Cube's graphene-based supercapacitors can achieve 100% recycling, solving the problem of battery pollution. More than one million safe charge and discharge have been achieved, and the product's charge and discharge speed is twice that of similar products on the market. At the same time, it can work safely between minus 40 degrees Celsius and 70 degrees Celsius. Supercapacitors can be used in any combination to increase capacitance as needed.
It is reported that the mass production of graphene-based supercapacitors can drive the development of the upstream graphite and graphene industries. At the same time, it can also promote the development of downstream application terminals such as wind power generation, smart grid, rail transit, heavy machinery and new energy vehicles.
At present, the company has perfected the first graphene supercapacitor production line with a yield of 98% and an annual output value of about 25 million yuan.
