Active material

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.

Binder

A polymer that holds electrode particles to each other and to the foil — typically PVDF for positive electrodes and CMC with SBR for graphite. It stores no charge, so cell designers use as little as the electrode needs.

Electronic conductivity

How readily a material conducts electrons. Current collectors and carbon additives supply it in an electrode because most active materials, LFP above all, conduct electrons poorly; a good electrolyte should have none, or it would self-discharge the cell.

Slurry

The mixture of active material, conductive carbon, binder and solvent that is coated onto a current-collector foil to make an electrode. Positive slurries use NMP as solvent; graphite slurries are water-based.
