On June 24, Cangzhou Mingzhu Plastic Co., Ltd. announced that its lithium-ion battery separator production expansion project has been fully completed. This commissioning involves the remaining production lines of the "annual 200 million square meter wet-process lithium-ion battery separator project" and the "annual 500 million square meter dry-process lithium-ion battery separator project." According to the announcement, the second production line (with an annual design capacity of 100 million square meters) under the wet-process project, which is being handled by the subsidiary Wuhu Mingzhu Separator Technology Co., Ltd., has recently commenced production. Concurrently, the remaining three production lines (with a combined annual design capacity of 300 million square meters) under the dry-process project, being handled by the subsidiary Cangzhou Mingzhu Lithium Battery Separator Co., Ltd., have also been completed and put into operation.

This Week, the Second-Life Application Market Was Generally Stable, while Ternary Products Weakened Slightly [SMM Weekly Review]

This week, the second-life application market operated steadily overall. Ternary product prices weakened slightly, while quotations for other categories remained basically stable. On July 30, the Ministry of Industry and Information Technology abolished the relevant second-life application policies and standards, and 100 second-life battery producers were removed from the compliance list. The industry entered a period of policy digestion, and the market's operating logic changed. Cost side, raw material price trends diverged: lithium carbonate edged up, cobalt sulphate continued to grind lower, and nickel sulphate was broadly stable. The raw material side had a limited impact on second-life costs. Supply side, as the policy took effect, inventory held by former second-life battery producers could no longer circulate under the "second-life" label, and the pace of flows to the recycling segment accelerated noticeably. Some enterprises offloaded goods at low prices to recover funds, putting some pressure on market prices. Demand side, core downstream applications such as e-bikes were explicitly prohibited by the policy, so second-life demand contracted directly. Wait-and-see sentiment was strong in sectors such as telecom backup power; downstream purchase willingness was generally low; and overall market transactions were relatively subdued. Looking ahead, the short-term market is expected to remain mainly stable. Under inventory diversion pressure, ternary products still have room to edge down slightly. The pace of detailed policy rollout and enforcement intensity will be key to the subsequent market trend.
