LMO
A manganese spinel positive material, LiMn₂O₄, that is cheap, safe and good at high power but suffers manganese dissolution and short life at elevated temperature. It is often blended with NMC rather than used alone. [1]
- Also called
- lithium manganese oxide, spinel
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 LMO alongside Cathode active material in this context. 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.
Use in Lemonergy
Separate chemistry from form factor.
This is a reference concept. No executable Lemonergy block has been verified for this term.
