This configuration targets the 300-350 Wh\/kg range, but it is notoriously difficult to manage due to the chemical and mechanical instability of both materials. The \"Dry\" stage is an absolute necessity here to perform extreme dehydration and to establish a baseline for the mechanical stress the cell will face once the silicon begins to expand.\u003c\/p\u003e\n\u003cp\u003eFor this chemistry, the dry assembly serves as the ultimate \"clean room\" gate: (1) Eliminating Lattice Moisture: NCM811 is extremely hygroscopic. Any moisture trapped in the \"Dry\" cell will react with LiPF6 (once injected) to form HF acid, which attacks the NCM surface and leaches transition metals. (2) \u003cstrong\u003eMechanical Baseline\u003c\/strong\u003e: Because Silicon expansion is so aggressive, the \"Dry\" cell allows you to measure the initial thickness and stack pressure of the cell before any cycling occurs. (3) \u003cstrong\u003eSi\/C Degassing\u003c\/strong\u003e: Silicon-carbon composites often have high internal porosity. Vacuum-sealing the dry pouch ensures that all air is removed from the anode pores, preventing \"dry spots\" where the electrolyte fails to penetrate.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eCLIBDPCNCM811SiC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eCell General Parameters\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eCell Capacity: 1.0 Ah\u003c\/li\u003e\n\u003cli\u003eCell Size: L80*W48*T2.0 mm\u003c\/li\u003e\n\u003cli\u003eStacking Mode\u003c\/li\u003e\n\u003cli\u003eMaterial: NCM811 + Si\/C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eNCM811 Cathode\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eElectrode Sheet: L75*W54 mm, 4 layers\u003c\/li\u003e\n\u003cli\u003eActive Portion: 97.0%\u003c\/li\u003e\n\u003cli\u003eDouble-Side Area Density: 36.0 mg\/cm2\u003c\/li\u003e\n\u003cli\u003eCompaction Density: 3.4 g\/cm3\u003c\/li\u003e\n\u003cli\u003eSpecific Capacity: 190 mAh\/g \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eSi\/C Anode\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eElectrode Size: L77*W56 mm, 5 layers\u003c\/li\u003e\n\u003cli\u003eActive Portion: 94.5%\u003c\/li\u003e\n\u003cli\u003eDouble-Side Area Density: 21.2 mg\/cm2\u003c\/li\u003e\n\u003cli\u003eCompaction Density: ~1.0 g\/cm3\u003c\/li\u003e\n\u003cli\u003eSpecific Capacity: 450 mAh\/g \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: 21.2405%;\"\u003eSeparator\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e9 um PE with double-side 3 um ceramic coatings. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eRecommended Electrolyte Amount\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e6.0 g\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/echemsupplies.com\/collections\/liquid-electrolytes\"\u003eLiquid Electrolytes\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eTest Voltage Range\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e2.5-4.2 V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003ePunched Airbag Design\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eYes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eTesting Processes\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e(1) Electrolyte Filling with recommended amount in glovebox.\u003cbr\u003e(2) First Time Aging: 45°C, aging time ≥ 15h in an oven.\u003cbr\u003e(3) Formation conditions: 45°C, 5 min rest; 0.02C constant current charging (10% theoretical capacity or 5 h); 0.1C constant current charging (30% theoretical capacity, 3 h); 5 min rest; total capacity is 40% or 8 h;\u003cbr\u003e(4) Second Time Aging: 45°C, aging time ≥ 24h in a oven\u003cbr\u003e(5) Battery Analyzer for charging and discharging.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.cell.com\/joule\/fulltext\/S2542-4351(20)30332-9\"\u003eZ.
