Energy / RESEARCH MAP 05
Batteries & Energy Storage
Who earns the return: material suppliers, manufacturers or operators?
From minerals and cells to installed storage systems.
Scope: Battery supply chains, with a stationary-storage operating lens. EV batteries and grid-storage revenue pools are not interchangeable.
Geography: Global supply chain; project economics depend on local power markets.
01 / HOW IT WORKS
Follow the value chain
DEX editorial map. Read left to right (top to bottom on mobile); companies may span several stages. Expand a stage to inspect its economics.
-
Materials & components
Miners, refiners and component suppliers
Provide battery-grade inputs and components.
Revenue & bottleneck — Materials & components
- Revenue models to investigate
- Material and component sales under spot or contract terms.
- Bottleneck to test
- Do quality, supply security and chemistry choices align?
-
Cells & systems
Cell makers, pack makers and system integrators
Turn components into a tested, controllable storage system.
Revenue & bottleneck — Cells & systems
- Revenue models to investigate
- Cell/system sales, integration and warranty services.
- Bottleneck to test
- Can manufacturing quality and warranty obligations be sustained?
-
Projects & operation
Developers, utilities and storage operators
Connect and operate assets to serve a particular power market.
Revenue & bottleneck — Projects & operation
- Revenue models to investigate
- Contracted or market-based power-system services.
- Bottleneck to test
- Will local revenues cover degradation and full project costs?
02 / FOLLOW THE MONEY · DEX INTERPRETATION
The business-model lens
Do not equate cheaper cells with better project returns. Connection, installation, financing, degradation and market rules belong in the same model.
03 / TEST THE THESIS · RESEARCH QUESTIONS
Signals to investigate. Risks to challenge.
Demand & adoption questions
- Where does variable generation create a need for flexibility?
- Can storage participate and get paid in the relevant local market?
What could weaken the thesis?
- Safety, degradation and warranties may change lifecycle costs.
- Supply concentration and changing project revenues can offset lower hardware prices.
04 / BUILD A WATCHLIST
Metrics worth tracking
Suggested research metrics, not measured values. Collect primary data with a date, geography and definition before making comparisons.
- Installed system cost
- Use consistent currency, date and system boundary; distinguish USD/kW from USD/kWh.
- Usable capacity & efficiency
- Measure at the same operating conditions and asset age.
- Contracted revenue share
- Separate contracted cash flows from merchant assumptions.
05 / CHECK THE EVIDENCE
Evidence anchors & sources
These sources support the statements below. They do not validate every editorial hypothesis, imply endorsement, or refresh the explorer's market estimates.
- The IEA describes concentration across battery supply chains and explains storage's role in flexibility and grid stability. Its 2024 scenarios are not treated here as current forecasts. [iea]
- Intergovernmental analysis
Batteries and Secure Energy Transitions — Executive summary
Supports: Supply-chain structure and power-system applications; historical scenarios, not fresh market estimates.
