Critical Minerals

EV Battery Critical Mineral Supply Chain Analysis

A research-facing workspace for tracing mining, post-trade, refining, and cathode transitions across the EV battery supply chain. This viewer switches between the Original export and the latest First Optimization result, with First Optimization synchronized from the conversion_factor_optimization engine into the published runtime snapshot.

Control Console

Access And Runtime Controls

Switch access mode, datasets, scenarios, year, result snapshot, and node scaling from one unified workspace.

Access

Guest mode is the default. Non-guest mode reveals diagnostics and production values after password verification.

Theme

Switch between the dark research surface and a white-background reading mode.

Metal

Ni, Li, and Co are currently active datasets. Mn remains reserved until its workbook set is connected.

Year

Co Scenario

Middle uses the workbook's Middle battery related row, while Max and Min switch the refining-side scenario bounds.

Result

Switch the Sankey diagram between the original exported result and the latest First Optimization snapshot synchronized from conversion_factor_optimization.

Reference Quantity (t)

Reference quantity changes the node-height scaling, following the 2.1 layout logic while still reading precomputed flows.

Diagram

Ni 7-Step Supply Chain

The viewer keeps the established seven-stage reading experience while figures now load from published Original and First Optimization runtime snapshots.

Order Studio

Stage Sorting, Continent Grouping And Aggregation

Use each stage card below to switch between By Size, Manual, and By Continent. Aggregation is reserved for a later iteration.

Diagnostics

Optimization Diagnostics

Diagnostics respond to the selected result mode.

Optimization Impact Overview Before/after SN reduction, main driver, node-type movement, and constraint pressure for the active optimization snapshot

Stage Comparison And Unknown Nodes Original versus First Optimization totals, split by each S1-S2-S3 style stage group and unknown-node type

Runtime Metadata Source, weights, scaling, and memo constraints condensed into grouped runtime cards

Coefficient Explorer Inspect a specific conversion coefficient, its recommended value, bounds, exposure, and related stage-flow changes.

Trade Flow Explorer Compare Original and First Optimization flows by stage group, source, target, special-node type, and change status.
