WHAT DOES NMC-BATTERY MEAN?

NMC stands for lithium-nickel-manganese-cobalt oxide and is a very common battery oxide.  These materials are used particularly in high-performance battery cells or accumulators with a very high energy density. This ranges from 230-250 Wh/kg for NMC batteries. NMC chemistry is a state-of-the-art technology that has established itself in conjunction with high safety requirements. A battery management system and an efficient thermal management system, such as immersion cooling, are required. NMC batteries are mainly used in notebooks, bicycle batteries, electric cars, cell phones and household and garden appliances. Today, LFP (lithium iron phosphate) is used for stationary power storage.

The nominal voltage of a single NMC battery cell is usually specified as 3.6 V or 3.7 V. The final charging voltage, which depends on the electrolyte composition, is often 4.2 V. In order to achieve the voltage, capacity and current required for a specific application, NMC cells are often configured and sold as battery packs. In these battery packs, the cells are connected in series and/or parallel. The number of cells connected in series determines the voltage, while the number of cells connected up in parallel can be used to vary the current and capacity.
