Some investors asked Wanrun Co., Ltd. on the interactive platform. They are concerned that the company has recently applied for fewer and fewer R&D patents. Is the company reducing R&D investment? Or are we concentrating our efforts on key issues? The company aspires to become the world's advanced materials manufacturer, so it must dare to create exclusive products first. Have other companies' lithium sulfide electrolyte pilot products been sent to downstream customers for verification? Please tell me what are the advantages of our lithium sulfide electrolytes compared to our competitors? Wanrun Co., Ltd. replied that in the first half of 2026, the company continued to invest in research and development in materials such as semiconductor manufacturing materials, polyimide materials, OLED materials, etc., in an effort to win more future market opportunities for the company. R&D expenses increased by 12 million yuan over last year. The company's pilot line for lithium sulfide, a solid-state battery material, has been completed according to the original plan. The pilot work is now underway, and sample delivery verification has not yet begun.
