Battery knowledge · Lithium-ion chemistries and cell formats
Coin cell
A small disc-shaped cell in a crimped steel case. Besides powering watches and key fobs, it is the standard laboratory format for testing a new electrode material against lithium metal.
- Also called
- button cell, CR2032
Example
Lithium-ion chemistries and cell formats: an example situation
Two cylindrical cells can share dimensions yet differ in cathode, capacity and current limits.
Read Coin cell alongside Half-cell in this context. A test cell with the electrode under study against lithium metal, so the measured potential is that electrode’s alone. It is how a new material’s capacity and voltage are first measured, usually in coin-cell format.
Use in Lemonergy
Separate chemistry from form factor.
This is a reference concept. No executable Lemonergy block has been verified for this term.
