隔膜，行业触底，涨价正当时!

Core Viewpoint - The diaphragm industry is undergoing a transformation from blind expansion to a return to healthy development, with a consensus on price discipline and capacity regulation reached during an industry meeting in late August [1][2]. Group 1: Price Trends - Since late August, the overall price of wet diaphragms has increased by approximately 7%, with expectations for continued price rebounds due to industry restructuring and supply-demand dynamics [2]. - Leading diaphragm manufacturers have initiated price hikes, which are now spreading to second-tier producers, focusing on customer structure optimization and order price increases to enhance profitability [1][2]. Group 2: Industry Profitability - Currently, only 2-3 companies in the diaphragm industry are profitable, while the majority, including leading company Enjie, reported losses, with Enjie’s loss reaching -93 million yuan in the first half of 2025 [2]. - The widespread losses in the industry are not conducive to sustainable development, and recent price increases are aimed at reversing this trend [2]. Group 3: Supply and Demand Structure - Global demand for lithium batteries is expected to exceed expectations in 2025, driven by new vehicle demand and rapid growth in the global energy storage market [3]. - Despite an overall supply surplus, there are structural supply contradictions, particularly among the top three diaphragm manufacturers, whose new capacity is limited, leading to high capacity utilization rates projected to exceed 95% in 2026 [3]. Group 4: Industry Feedback - Diaphragm manufacturers are implementing significant price increases, with average hikes in the double digits, while battery manufacturers express concerns over the steep price increases and the need to ensure supply continuity [4][5]. - Battery manufacturers are facing challenges in securing diaphragm supplies, as the certification process for new suppliers can take at least a quarter, complicating their ability to switch suppliers [5]. Group 5: Future Outlook - The industry is expected to see a continued tightening of supply, with top manufacturers maintaining full production status and limited new capacity, leading to a forecasted capacity utilization rate of over 85% in the wet diaphragm sector [10].
