Lithium metal anode
A negative electrode made of lithium metal itself. It stores about ten times more charge per gram than graphite, which is the main attraction of solid-state cells, but it is reactive and prone to uneven deposits. [1]
Example
Cell components and electrode materials: an example situation
Electrons travel through additive, foil and tab; ions use electrolyte and separator pathways.
Read Lithium metal anode alongside Anode-free cell in this context. A lithium-metal cell assembled with bare copper foil as the negative electrode; the first charge plates all its lithium out of the positive material. It maximises energy density but every lost lithium atom is lost capacity.
Use in Lemonergy
Connect each material with its function.
This is a reference concept. No executable Lemonergy block has been verified for this term.
