Single-crystal cathode
Positive-electrode powder made of individual micron-sized crystals rather than agglomerates of many small grains. With no internal grain boundaries to crack open, it resists particle cracking and gassing and lasts longer at high voltage.
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 Single-crystal cathode 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.
