{"product_id":"erpccevesm","title":"ECS-R Economic Vacuum Electrolyte Standing Machine for Pouch\/Cylindrical Cells, ERPCCEVESM","description":"\u003cp\u003eA Vacuum Electrolyte Standing (Soaking\/Diffusion) Machine is a dedicated piece of post-injection battery equipment used in both laboratory pilot lines and mass manufacturing of pouch, cylindrical, and prismatic lithium-ion, sodium-ion, and supercapacitor cells. While the injection machine introduces liquid electrolyte into the cell casing, the standing machine applies controlled, multi-stage vacuum-pressure cycling and high-temperature soaking to drive the viscous liquid deep into the dense, microporous structure of the electrodes and separator.\u003c\/p\u003e\n\u003cp\u003eThe vacuum electrolyte standing machine normally includes the following procedures: (1) \u003cstrong\u003eCell Loading \u0026amp; Chamber Evacuation\u003c\/strong\u003e: Cells are loaded into multi-tray standing chambers (or individual vacuum fixtures for cylindrical\/prismatic cells). Chambers are sealed and evacuated to target vacuum levels (typically -90 kPa to -98 kPa) to extract residual air pockets trapped inside the internal cell stack. (2) \u003cstrong\u003eCyclic Pressure \u0026amp; Vacuum Diffusion (Pressure Pulsing)\u003c\/strong\u003e: The machine alternates between deep vacuum and controlled pressure backfilling (using dry N2, Ar, or dry air). Deep vacuum expands trapped micro-bubbles (N2\/O2) and draws them out of capillary channels, while positive pressure pushes the liquid electrolyte into sub-micron pores of thick cathodes (e.g., high-nickel NMC, LFP) and dense graphite\/silicon anodes. (3)\u003cstrong\u003e Thermostatic Thermal Soaking\u003c\/strong\u003e: Integrated heating platens or circulating hot air maintain an elevated temperature (35-55 °C). Elevating temperature lowers the viscosity and surface tension of carbonate solvents, significantly accelerating wetting kinetics without decomposing heat-sensitive lithium salts (LiPF6, LiFSI). (4) \u003cstrong\u003eMechanical Clamping \u0026amp; Pressure Equalization (Optional)\u003c\/strong\u003e: For pouch cells, soft-pack pneumatic or spring-loaded clamping platens apply uniform mechanical pressure (0.05 MPa - 0.3 MPa) across the face of the pouch.\u003c\/p\u003e\n\u003ctable width=\"613\" style=\"height: 705.2px;
