      "definition": "A liquid resin — polyurethane, silicone or epoxy, sometimes foamed — poured around cells or electronics and cured into a solid block. It fixes cells against vibration, insulates them and can slow thermal propagation; some structural packs fill every gap between cylindrical cells with it. The cost is mass and a pack that is hard to repair or recycle.",
