Mid-nickel cathode
An NMC with roughly 50–70 % nickel, such as NMC532 or NMC622. Charging it to higher cut-off voltages, about 4.3–4.4 V and often as single crystals, recovers much of the capacity of high-nickel grades while keeping better thermal stability, lower cost and longer life — a common compromise for mainstream EV cells.
- Also called
- mid-Ni, high-voltage mid-nickel, NMC532, NMC622
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 Mid-nickel cathode alongside High-nickel cathode in this context. A layered oxide with 80 % or more nickel, such as NMC811 or NCA. Nickel raises capacity and lowers cobalt content, but the material is less thermally stable, more sensitive to moisture and ages faster at high voltage.
Use in Lemonergy
Separate chemistry from form factor.
This is a reference concept. No executable Lemonergy block has been verified for this term.
