{"product_id":"csscctcf","title":"Compression Fixture for Solid-State Coin Cell (CR20XX) Test, CSSCCTCF","description":"\u003cp\u003eWhen testing all-solid-state batteries (SSBs) in a coin cell format, standard internal wave springs are entirely inadequate. Solid-state systems require significantly higher, well-controlled external mechanical pressure—typically between 5 MPa and 15 MPa (and sometimes up to 30+ MPa for processing or high-rate cycling)—to maintain intimate solid-to-solid contact and prevent interfacial void formation during lithium stripping.\u003c\/p\u003e\n\u003cp\u003eThe primary functions of the compression fixture are shown below: (1) \u003cstrong\u003eSuppressing Volume Expansion\u003c\/strong\u003e: Anodes containing silicon or alloy materials undergo substantial volumetric change during lithiation. The compression fixture provides an external clamping force to prevent structural pulverization and layer delamination. (2) \u003cstrong\u003ePreventing Interfacial Voids\u003c\/strong\u003e: In solid-state battery testing, high stack pressure (often 5 MPa to 15 MPa) is mandatory to maintain intimate solid-to-solid contact at the electrode\/electrolyte interface, compensating for material creep during stripping and plating. (3) \u003cstrong\u003eEliminating Contact Resistance\u003c\/strong\u003e: By applying a calibrated mechanical load, the fixture ensures stable, reproducible 4-wire (Kelvin) electrical contact, driving down parasitic Area Specific Resistance (ASR) to reveal true intrinsic material performance.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 316.462px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 38.8625px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 38.8625px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 38.8625px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSSCCTCF (C-SSCCT-CF)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 39.2px;\"\u003e\u003cem\u003eLocating Slot\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eD=20 mm (suitable for CR20XX coin cells, such as 2016, 2025, 2032)\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003eSS304 body + PTFE insulating pad\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 55.2px;\"\u003e\u003cem\u003eCompression Pressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 55.2px;\"\u003e\n\u003cp\u003eMax. 800 MPa (normally 300 MPa for solid-state coin cell test)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 108.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 108.4px;\"\u003e\u003cem\u003eAssembling Flow Chart\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 108.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CSSCCTCF_flow_chart_160x160.jpg?v=1782626179\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 39.2px;\"\u003e\u003cem\u003eProduct Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 39.2px;\"\u003e60mm*30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \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.sciencedirect.com\/science\/article\/abs\/pii\/S2451910321002301\"\u003eY.
