Gelonghui, April 12 | Xinlun New Materials (002341.SZ) said on the investor interactive platform that compared with traditional electrolyte lithium batteries, all-solid-state lithium batteries require higher performance indicators for aluminum-plastic films and are more difficult to produce. The company is jointly developing next-generation aluminum-plastic film packaging materials that can be applied to all-solid-state lithium batteries with Japan's Toppan Printing (TOPPAN) Co., Ltd., and is currently supplying and verifying small-batch supply to well-known Japanese car companies.
