The coating performance of bio-based aramid is similar to that of traditional aramid, both of which can enhance the thermal stability of coated separator products and improve the wettability of lithium battery electrolyte. They are mainly applied in downstream lithium battery products such as large lithium batteries. The use of bio-based aramid for coating processing can reduce the production cost of aramid coated separator products and at the same time minimize the environmental impact of using organic solvents. In order to achieve the strategic development plans of all parties and combine the company's accumulated coating process technology with Anhui Liko's production technology in the field of bio-based materials, the company recently signed a "Shareholder Agreement" with Prosperix International Inc. Both parties jointly initiated the establishment of Prosperix International Inc. to accelerate the industrial application of bio-based aramid materials in the field of diaphragm coating processing.
