Real-World Applications and System Integration

Translating cell-level chemistry into a deployable pack is a systems problem — and the design that results is dictated as much by the application’s priorities and the target market’s regulations as by the electrochemistry.

An EV pack, a grid installation, a satellite, and an implant impose incompatible priorities: energy density against safety against reliability against mass. Each resolves to a different chemistry, form factor, and enclosure, because the consequence of failure — stranded grid energy, a ruptured satellite, a stopped heart — defines the design more than the chemistry does.

Fig. 6.0 — The same cell, four design briefs. Each application weights the priorities differently: EVs and aerospace chase energy density and low mass; grid storage subordinates both to cost-per-kWh and cycle life; medical and aerospace put reliability first. No single cell optimises all six.

One cell, four ways

Across these applications the same lithium-ion chemistry is selected, packaged, and qualified four different ways. The electrochemistry is a starting point; the failure consequence is what shapes the pack, the enclosure, and the qualification regime.

What this section covers

The topics work from the highest-volume application outward. Electrified transportation covers EV pack architecture, the shift to 800 V and cell-to-pack designs, and the global safety standards reshaping them. Stationary, aerospace, and medical integration then maps the other three corners of the design space — grid storage, satellites, and implants — each with its own dominant constraint.
