The table below compares the three most commonly used chemical classes in LIB batteries for grid-tied LIB battery systems and major manufacturers. Other chemistries for LIB batteries such as LCO, LMO and NCA are not used for grid energy storage and are therefore not included in this table. Figures in this table are obtained from battery manufacturers, product or system suppliers. NMC is the most popular of the three chemical groups due to high production output and reduced cost in the automatic machinery industry. NMC batteries have a high energy density but use cobalt. The environmental challenges of using cobalt are described in the “Environment” section.
LFP batteries do not use cobalt in the cathode, but are not as commonly used as NMC, and therefore typically cost more, mainly due to lower production output.
Both the NMC and LFP batteries have a graphite anode. The main cause of degradation of LIB batteries using NMC and LFP chemicals is the separation of the graphite layer and electrode degradation, which occurs during the storage process.
LIB batteries using LTO chemicals are the most expensive of the three chemicals. In LTO batteries, the graphite anode is replaced by a Lithium titanate anode. The cathode of an LTO battery can use NMC, LFP, or another chemical for the battery's cathode. LTO batteries are characterized by their long service life and large number of charge cycles.
