Cell-to-chassis

Integrating the cells into the vehicle floor itself, so the battery enclosure is the chassis and the cells help carry its loads. It saves mass and height but binds the battery to the car for life.

Cell-to-pack

Building the pack directly from cells without the intermediate module, using large-format cells that bear load themselves. It raises the cell-to-pack ratio and cuts parts, at the cost of making the pack harder to service.

Design for recycling

Choosing pack and cell constructions — bolted rather than glued modules, labelled chemistries, no potting — that make end-of-life dismantling fast and safe. It trades a little production convenience for a large saving at the recycler.

Dismantling

Taking a pack apart down to modules or cells to recover the casing, busbars, cables and electronics separately and to send only the cells on. It is still largely manual; robotic disassembly is held back by the variety of designs, glue and potting.

Potting compound

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.

Thermally conductive adhesive

An adhesive loaded with ceramic filler that both bonds cells to the cooling plate or tray and conducts their heat, typically at 1–3 W/(m·K). Unlike a gap filler it carries load, which suits cell-to-pack designs but makes cells hard to remove for repair or recycling.
