China Sun Group, which has the second largest cobalt series production capacity in China, says it has made technological improvements to its production line by increasing the lifetime and performance of mixing bowls used during anode material production.
In its press release, the company says its in-house technical staff has developed a new material that enables the mixing bowl to achieve uniform heat conduction and increase the stability of anode materials. As a result of the company's new innovation, the life cycle of the bowl's use has been extended from 30 uses per bowl to 180 uses per bowl. At the same time, the working temperature inside the bowl can be raised from 900 degrees Celcius to 1280 degrees Celcius, shortening the thermal treatment process from 6.5 hours to 5 hours.
"The versatility of this unique material enables us to increase production of anode materials, while lowering our direct costs from RMB1.26 to RMB0.44 per bowl use, or US$0.18 to US$0.06 per bowl use. The total cost of our finished goods can be now be decreased by RMB820 per ton or US$116 per ton," said Wang Bin, CEO of China Sun Group.
