ASC-IP: Isostatic Pressure Cell for Advanced Pouch Cell Testing The ASC-IP is a novel electrochemical test cell designed to evaluate pouch cells under fully isostatic pressure conditions — a significant evolution from conventional uniaxial setups. Built to meet the increasing demand for precision in solid-state battery (SSB) research, the ASC-IP allows researchers to apply uniform hydrostatic pressure (up to 6 MPa) across the entire cell surface, eliminating mechanical anisotropy and enabling more reliable data on stress-sensitive behaviors such as interfacial stability and ionic transport. What makes the ASC-IP unique is its built-in pressure monitoring system with direct analog output to a potentiostat or cycler. This feature enables real-time synchronization of mechanical and electrochemical data, offering unprecedented insights into how pressure influences performance and degradation. The compact cell accommodates various pouch cell sizes (up to 108 × 75 × 10 mm) and tab geometries, with repositionable clamp- or screw-based electrical connectors and thermocouple access for temperature monitoring (0–80 °C). A manual hydraulic pump is included for precise pressure control, supported by both visual (manometer) and digital pressure feedback. In solid-state battery testing, where interfacial contact and stack pressure are critical variables, the ASC-IP introduces a new standard — transforming pressure from a passive constraint into an active research variable.
