Celgard is globally recognized for our battery and material science expertise, and we take pride in the teams of engineers, scientists, PhDs, and technical specialists who help keep us at the 𝙘𝙚𝙣𝙩𝙚𝙧 𝙤𝙛 𝙢𝙚𝙢𝙗𝙧𝙖𝙣𝙚 𝙞𝙣𝙣𝙤𝙫𝙖𝙩𝙞𝙤𝙣. 𝗖𝗲𝗹𝗴𝗮𝗿𝗱® 𝗖𝗼𝗼𝗹𝗦𝘁𝗮𝗰𝗸™ 𝗦𝗲𝗽𝗮𝗿𝗮𝘁𝗼𝗿𝘀 – our latest #InnovativeSeparatorSolution – features a unique adhesive coating formulation and technique that provides strong electrode-separator adhesion at lower temperatures than typical adhesive coated separators available on the market today. Now in advanced development stage, 𝗖𝗲𝗹𝗴𝗮𝗿𝗱® 𝗖𝗼𝗼𝗹𝗦𝘁𝗮𝗰𝗸™ 𝗦𝗲𝗽𝗮𝗿𝗮𝘁𝗼𝗿𝘀 have been designed to enhance battery performance by optimizing the electrode-separator interface and can improve manufacturing productivity and yields* in Z-fold / heat press cell assembly processes. *𝘖𝘯𝘦 𝘩𝘦𝘢𝘵 𝘱𝘳𝘦𝘴𝘴 𝘦𝘲𝘶𝘪𝘱𝘮𝘦𝘯𝘵 𝘮𝘢𝘯𝘶𝘧𝘢𝘤𝘵𝘶𝘳𝘦𝘳 𝘳𝘦𝘤𝘰𝘳𝘥𝘦𝘥 𝘢𝘵 𝘭𝘦𝘢𝘴𝘵 50 𝘴𝘦𝘤𝘰𝘯𝘥𝘴 𝘪𝘯 𝘴𝘵𝘢𝘤𝘬 𝘱𝘳𝘦𝘴𝘴 𝘵𝘪𝘮𝘦 𝘴𝘢𝘷𝘪𝘯𝘨𝘴 𝘢𝘯𝘥 𝘦𝘴𝘵𝘪𝘮𝘢𝘵𝘦𝘥 2-4% 𝘪𝘯 𝘊𝘈𝘗𝘌𝘟 𝘴𝘢𝘷𝘪𝘯𝘨𝘴 𝘸𝘩𝘦𝘯 𝘶𝘴𝘪𝘯𝘨 𝘊𝘦𝘭𝘨𝘢𝘳𝘥® 𝘊𝘰𝘰𝘭𝘚𝘵𝘢𝘤𝘬™ 𝘴𝘦𝘱𝘢𝘳𝘢𝘵𝘰𝘳𝘴 𝘷𝘴. 𝘴𝘵𝘢𝘯𝘥𝘢𝘳𝘥 𝘩𝘦𝘢𝘵 𝘢𝘤𝘵𝘪𝘷𝘢𝘵𝘦𝘥 𝘢𝘥𝘩𝘦𝘴𝘪𝘷𝘦 𝘤𝘰𝘢𝘵𝘦𝘥 𝘴𝘦𝘱𝘢𝘳𝘢𝘵𝘰𝘳𝘴. 🔋 To learn more, 𝗰𝗵𝗲𝗰𝗸 𝗼𝘂𝘁 𝗼𝘂𝗿 𝗽𝗼𝘀𝘁𝗲𝗿 𝘁𝗵𝗶𝘀 𝘄𝗲𝗲𝗸 𝗮𝘁 𝘁𝗵𝗲 𝗜𝗻𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗕𝗮𝘁𝘁𝗲𝗿𝘆 𝗦𝗲𝗺𝗶𝗻𝗮𝗿 & 𝗘𝘅𝗵𝗶𝗯𝗶𝘁 (𝗜𝗕𝗦𝗘) – proudly sponsored by Asahi Kasei – or visit: https://lnkd.in/e5iXQcgS #Celgard #BatterySeparator #InnovativeSeparatorSolutions #BatteryIndustry

Come join us next week at the International Battery Seminar & Exhibit (IBSE) in Orlando, FL, USA! 🔋 Don’t miss hearing our CTO/CSO Dr. Zhengming (John) ZHANG give a technical presentation on the Mechanisms to Study and Solutions for Preventing Thermally Runaway in Lithium-ion Cells on Tuesday, 3/18 at 11:30 AM (Advances in Cell Manufacturing Track). 💡 Check out our poster on recent Celgard® Separator Innovations – including Celgard® CoolStack™ Battery Separators, our latest product in advanced development stage. This novel platform enables electrode-separator adhesion at lower temperatures relative to standard adhesive coated separators – allowing cell manufacturers that utilize Z-fold / heat press assembly processes to enhance productivity and improve yields. To learn more about Celgard® CoolStack™ separators or our other #InnovativeSeparatorSolutions, request a meeting with the Celgard team through the Celgard website at: www.celgard.com/contact-us To register for the IBSE event: https://lnkd.in/eC4GvaW #Celgard #BatterySeparator #InnovativeSeparatorSolutions #BatteryIndustry

Did you know that the polypropylene-based materials used to create Celgard® microporous membranes are completely perfluorocarbon (PFC) and per- and polyfluoroalkyl substances (PFAS) free*? Our membranes are produced using a unique “dry stretch” manufacturing process that creates a porous structure without the use of solvents and results in a low carbon footprint. They are also recyclable and fully compatible with polypropylene waste streams. To learn more: https://lnkd.in/eNPabRRs *Our raw material suppliers confirm they do not intentionally add PFAS and independent lab testing verifies results below the detection limit. #Celgard #PFASfree #SolventFree #BatterySeparator

Initial testing of our new Celgard® DuraWet™ Enhanced Wettability Separators shows decreased separator electrical resistance by up to 30% relative to other polyolefin membranes, improving cycle life and battery performance and under a variety of test conditions, including at low temperatures.
