Anode-free cell
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.
- Also called
- zero-excess lithium
Example
Other and emerging chemistries: an example situation
Two chemistries can meet the same energy target with different voltage windows and charge termination.
Read Anode-free cell alongside Coulombic efficiency in this context. Charge delivered on discharge divided by charge put in on the previous charge. A healthy lithium-ion cell exceeds 99.9 %; the missing fraction is lithium lost to side reactions, so CE is an early and sensitive aging signal.
Use in Lemonergy
Do not carry lithium-ion assumptions into every chemistry.
This is a reference concept. No executable Lemonergy block has been verified for this term.
