Cathode Active Material & Precursor Manufacturing calculator
Lithium Excess Cost Calculator
Estimate the cost of lithium hydroxide or lithium carbonate added above stoichiometric requirement for CAM synthesis. Quantity times rate times capture factor, plus a fixed adjustment, builds a defensible weighted cost.
What this calculator does
- Estimate the cost of lithium hydroxide or lithium carbonate added above stoichiometric requirement for CAM synthesis.
- Use it when lithium excess cost in cathode active material and precursor manufacturing is being put through a cathode active material and precursor manufacturing weighted-cost review.
- Turns stoichiometric lithium source required, lithium source cost, lithium excess addition into a weighted cost for lithium excess cost in cathode active material and precursor manufacturing.
Formula used
- Variable lithium excess cost = stoichiometric lithium source required × lithium source cost × lithium excess addition
- Total lithium excess cost = variable lithium excess cost + fixed lithium handling cost
Inputs explained
- Stoichiometric lithium source required: Use the lithium hydroxide or lithium carbonate mass required by the CAM recipe before excess addition.
- Lithium source cost: Use delivered lithium hydroxide, lithium carbonate, or customer-specified lithium source cost.
- Lithium excess addition: Enter the extra lithium percentage added to compensate for volatilization, side reactions, or target Li:M ratio.
- Fixed lithium handling cost: Add assay, drying, storage, charging, or lot-change cost tied to the lithium addition.
How to use the result
- Use it when lithium excess cost in cathode active material and precursor manufacturing is being scored for capture or weighted cost.
- Risk-adjustments and discount rates are not in the formula; layer them on top for capital reviews.
Common questions
- What problem does this lithium excess cost calculator solve? Estimate the cost of lithium hydroxide or lithium carbonate added above stoichiometric requirement for CAM synthesis. You get a weighted cost you can defend before quoting, scheduling, or sign-off.
- Which inputs change the weighted cost the most? stoichiometric lithium source required, lithium source cost, lithium excess addition usually move the weighted cost most. Pull from measured cathode active material and precursor manufacturing runs, supplier data, and recent quotes rather than memory.
- What do I do with this number? Use the weighted cost in the cathode active material and precursor manufacturing business case or quote build-up.
- What should I verify first? Confirm the capture factor is honest; over-stated capture is the most common reason these models miss.
