Cathode active material

The lithium-containing compound in the positive electrode — NMC, NCA, LFP or LCO powder — that supplies the cell’s cyclable lithium. It is the most expensive material in most cells and sets the nominal voltage and much of the energy density. [1]

Abbreviation
CAM

Example

Cell components and electrode materials: an example situation

Electrons travel through additive, foil and tab; ions use electrolyte and separator pathways.

Read Cathode active material alongside Active material in this context. The part of an electrode that actually stores lithium — graphite on the negative side, an oxide or phosphate on the positive. It makes up most of the electrode coating; the rest is binder and conductive additive.

Use in Lemonergy

Connect each material with its function.

This is a reference concept. No executable Lemonergy block has been verified for this term.
