NMC cathode powder

One kilogram of NMC532 cathode active material

This page shows what the product is made of and where each figure comes from. It shows no death toll. The toll is computed from this bill of materials from session 19, and published only once it has an uncertainty interval and has passed a backtest.

Lithium nickel manganese cobalt oxide, LiNi0.5Mn0.3Co0.2O2 (NMC532), made by calcining a co-precipitated precursor with lithium carbonate. Argonne's report names NMC532 as a chemistry holding a significant share of the current battery market, and it is the one chemistry whose whole chain — cathode, precursor, metal salts — this source publishes, so it is modelled end to end from that one document. Cathode powder is where a battery's cobalt, nickel and lithium enter.

What it is made of

Each line is one component of one kilogram of NMC532 cathode active material: how much of it goes in, how much had to be produced for that, and where the figure comes from.

Table 5 gives 0.945 t of precursor and 0.381 t of Li2CO3 per tonne of NMC532; Table 7 gives the precursor's metal sulphates. The contained metal follows from the molar masses: 0.945 x 0.868 t NiSO4 x 0.3793 Ni = 311.11 g of contained nickel per kilogram

Table 5 gives 0.945 t of precursor and 0.381 t of Li2CO3 per tonne of NMC532; Table 7 gives the precursor's metal sulphates. The contained metal follows from the molar masses: 0.945 x 0.494 t MnSO4 x 0.3638 Mn = 169.85 g of contained manganese per kilogram. Manganese is not in HumanToll's materials register, so this mass reaches no supply chain Registered as the material `manganese` on 2026-09-18 from USGS mine production.

Down to raw materials

The whole chain multiplied out — everything one kilogram of NMC532 cathode active material needs, through every intermediate product, with every loss on the way included.

Input Per functional unit
Cobalt 126 g
Lithium 71.6 g
Manganese 170 g

An input marked “not in the register” is counted by mass and reaches no supply chain yet. Industries appear as the euros or tonne-kilometres the bill of materials gives them.

How much of it is explicit

100% of this product’s mass is explicit in its own bill of materials.

Its whole chain draws on 1.00 kg of materials, losses included. 68% of that is registered raw materials — the part the model can trace harm to — 32% is inputs not yet in the register, and 0% is a declared remainder.

In the input–output model it belongs to “Manufacture of chemicals and chemical products” (FIGARO industry C20).

The number this page does not show

The harm in this chain is not shown.

The model allocates the harm counted where each raw material is produced to the products that use it. That number is a count of people with a run behind it and no uncertainty interval yet, and nothing of that kind is published before the backtest of session 21. What this page can show without it is the structure: what the product is made of, and where each part of that knowledge comes from.
