Cathode / anode materials & precursors — deep, competitive, and cost-leading.
Components & modules — a very long tail of capable but uneven suppliers.

China's lead is clearest in electrical machinery and vehicle exports, which together represent the largest industrial export categories by value.

The risk tiers

Tier-1 cell makers — pass overseas audits, have export track record, documented QA. Premium price, low risk.
Established component suppliers — solid, but verify ca
