(1) \u003cstrong\u003ePorosity Control\u003c\/strong\u003e: The primary goal is to reach a \"target porosity\" (typically 25%–35%). This balance is critical: too high, and the energy density is low; too low, and the electrolyte cannot penetrate the pores, leading to poor performance on your Neware testers. (2) \u003cstrong\u003eElastic Recovery\u003c\/strong\u003e: Because the process is cold, the material may experience more \"spring-back\" (elastic recovery) once it leaves the nip. To compensate, the gap must be set slightly tighter than the final desired thickness.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 201.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESLECHPCCRP (ESL-EC-HPCCRP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V or AC380V±10%, single-phase, 50\/60Hz, 6000 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCold Roller\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eΦ320x370mm mm (effective width for cold rolling: \u003cspan style=\"color: rgb(255, 42, 0);\"\u003e350 mm\u003c\/span\u003e)\u003c\/li\u003e\n\u003cli\u003e9Cr3Mo, surface coated with chromium layer with a thickness of  ≥0.08mm\u003c\/li\u003e\n\u003cli\u003eHRC65~70, hardness layer thickness ≥18mm\u003c\/li\u003e\n\u003cli\u003e5.5 KW AC frequency conversion motor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eHydraulic Pressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 100T, adjustable in HMI touch screen\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Speed\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0.3-8.0 m\/min, digital display, adjustable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Gap\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-1.5 mm, digital display and adjustable\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Effect\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e± 2 μm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eRoll-to-Roll Integration (\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eOptional\u003c\/span\u003e)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eA roll-to-roll unit can be integrated on the cold rolling press for electrode roll calendering \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"text-align: start;\"\u003e            \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESLECHPCCRP_02_100x100.png?v=1775843588\" style=\"margin-bottom: 16px; float: none;\"\u003e    \u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEach time the reduced thickness is 20%-25%.
