Virgin material

Raw material extracted from mines or brines rather than recovered by recycling. Recycled-content rules count the share of a battery's cobalt, lithium, nickel and lead that did not come from virgin sources.

Also called
primary raw material

Example

What the loop lacks is bought virgin

An NMC 622 batch of 8000 kg needs 573 kg of lithium; with 500 kg recovered, 73 kg is bought virgin and the batch’s lithium is 87 % recycled.

w_Li is 0.0716 in NMC 622. A recovered surplus beyond the recipe is left over and does not raise the batch’s recycled share above 100 %.

How the cathode is made, as a labelled cutaway with numbered steps.
Cathode: how the unit works. Drawn by the Lemonergy recycling study for 100 returned NMC 622 packs of 60 kWh through mechanical + hydrometallurgy. The numbers match the steps below. Redraw it for your own fleet in the recycling study ↗
  1. Balance the recipe: NMC 622 is LiNi0.6Co0.2Mn0.2O2. Of the elements that must come from the loop, Mn runs out first, so it sets the batch: 7942 kg.
  2. Co-precipitate: the nickel, cobalt and manganese sulfates are dissolved and precipitated together as a mixed hydroxide precursor, with ammonia controlling particle growth.
  3. Top up: 70.3 kg of Li is bought virgin, which lowers the recycled content of Li.
  4. Fire: the mixture is fired in ceramic trays and it becomes NMC622 cathode, with recycled content Li 88%, Ni 100%, Co 100%, Mn 100%.

An element allowed to be bought tops the batch up to its recipe, which lowers the recycled share of that element.

An NMC 622 batch of 8000 kg needs 573 kg of lithium; with 500 kg recovered, 73 kg is bought virgin and the batch’s lithium is 87 % recycled.

m_virgin = max(0, w_e × m_CAM − m_e,recovered); recycled share = 1 − m_virgin / (w_e × m_CAM)

Illustrative model. w_Li is 0.0716 in NMC 622. A recovered surplus beyond the recipe is left over and does not raise the batch’s recycled share above 100 %.
