(2) \u003cstrong\u003eCore-Shell Interfacial Stabilization\u003c\/strong\u003e: Utilizing Li5.4PS4.4Cl1.4}F2@0.2LiF powder prevents high-voltage electrolyte decomposition and transition metal dissolution during aggressive 20C high-rate pulses. (3) \u003cstrong\u003eLow-Temperature (-10°C) Kinetics Management\u003c\/strong\u003e: Incorporating high-conductivity thio-halide pathways ensures sufficient ionic conductivity (\u0026gt; 10^{-3} S\/cm) down to -10°C, while integrated thermal management films enable rapid self-heating prior to cold fast-charging. (4) \u003cstrong\u003eHigh-Temperature (80°C) Thermal Stability\u003c\/strong\u003e: High-molecular-weight PTFE dry binder and thermally stable core-shell sulfide frameworks prevent short circuits and structural delamination under extreme thermal stress up to 80°C.\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\u003eCFCASSPC20Ah\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 Size\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eL187mm * W87mm * T10.6 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eNominal Voltage \u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e3.7 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%;\"\u003eVoltage Range\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e2.75-4.2 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%;\"\u003eCapacity \u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e20 Ah (\u0026gt;270 Wh\/kg, \u0026gt;560 Wh\/L)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eFast-Charging\/Discharging Rate\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e5C charging\/10C discharging\/20C for momentary discharge\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eStability\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e800 cycles (1C\/1C, 100% DOD)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 21.2405%;\"\u003eOperation Temperature\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e-10-80 °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%;\"\u003eCell Resistance\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e1.0±0.4 mΩ\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 Weight\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e~300 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%;\"\u003ePackage Grade\u003c\/td\u003e\n\u003ctd style=\"width: 77.5191%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e1 pcs\/pack\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 \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/pubs.rsc.org\/eb\/article\/1\/6\/1353\/312960\/From-mold-to-Ah-level-pouch-cell-design-bipolar\"\u003eW.
