In the framework

What the capability covers and what it leaves to others, and the indicators it will be measured by.

Bounds

Covers storage technology from chemistry to cell and pack manufacture; grid-scale installations belong to Strategic Infrastructure, and battery-materials supply reads at the control layer, shared with the materials group.

Lineage

Carried from v0.0 (formerly Electric batteries) with the same identifier, absorbing Supercapacitors (retired): one storage capacity, two chemistries, with the distinction living at the indicator layer.
