Single-Crystal LiNi0.5Co0.2Mn0.3O2 (NCM523) Powder for High-Voltage (~4.35 V) Li-Ion Battery Cathode, 100 g/bottle, CLIBCSCNCM523

NCM523 has a 2D layered crystal structure that allows lithium ions to be inserted and removed efficiently. NCM523 is best understood as the "balanced" or "mainstream" option within the NMC family. It sits in a sweet spot, balancing the trade-offs between the older, more stable NCM111 and the newer, higher-energy NCM811.

The single-crystal NCM523 particles have following features: (1) Structure: It has zero internal grain boundaries. It is one solid, monolithic crystal. (2) The Advantage: When the particle swells and shrinks, there are no internal seams to crack. It is structurally robust and can withstand the mechanical stress of cycling for thousands of F-cycles. (3) The Result: An dramatic increase in battery lifespan and durability.
