An energy storage supercapacitor project with an aggregated investment of three billion yuan ($428 million) was inaugurated at Nantong National High-tech Industrial Development Zone in February 2017.

The project undertaken by Jianghai Energy Storage Technology in Nantong, Jiangsu province, was put into operation in the first half of 2019.

In the Nantong workshop of Jianghai Energy Storage,a batch of supercapacitors were being processed and assembled. Due to the high technical content of the product, a dry environment is required, so the entire workshop had to be sealed.

Jiang Hanbing, assistant to the general manager and senior engineer of the company, said the production process demands a high level of environmental requirements.

"The humidity in the external environment is generally more than 30 percent or even higher, but the humidity in the workshop should only maintain a fixed value of 0.2 percent," Jiang said. "Only a standard production environment can produce a product that will achieve excellent performance."

The provincial-level project has a total investment of three billion yuan, including 1.2 billion yuan in the first phase to build the supercapacitor project. The second phase has investment of 1.8 billion yuan.

A supercapacitor is an energy storage device widely used in the fields of new energy vehicles, rail transit and micro-power grids. About 90 percent of China's demand for supercapacitors relies on developed countries and regions.

Compared with the traditional aluminum electrolytic capacitor, the supercapacitor is more suitable for the large energy workplaces that require quick charging and quick discharging. Supercapacitors have expanded energy storage capacity by about one million times, and are widely used in the fields of new energy, automobiles and the military industry.

"Now 30 to 40 percent of the capacity has been achieved. Next, we will focus on producing parts for the equipment and production line," said Jiang. He added that orders are now pouring in, and sales and output are expected to double in 2020.
