Enhanced Thermal Stability and Extended Cycle Life

Optimized mid-nickel cathode for high-performance lithium-ion batteries


Overview | Product Information | MSDS | Related Products | Technical Support


Single crystal NMC631 (CAS 346417-97-8) is a mid-nickel cathode material engineered to deliver an optimal balance of energy density, thermal stability, and long-term durability. Compared to high-nickel NMC materials, this powder offers enhanced thermal stability and extended cycle life. Additionally, NMC631 provides higher energy density than low-nickel NMC compositions, making it an ideal "performance–stability balance" material. Unlike conventional polycrystalline cathodes that form secondary agglomerated particles, single-crystal NMC631 consists of discrete, robust primary particles. The absence of internal grain boundaries significantly reduces microcracking during cycling.

Single-crystal NMC631 also demonstrates excellent thermal compatibility with solid-state electrolytes such as LLZTO, maintaining structural phase integrity at temperatures up to 1000 °C. In all-solid-state lithium batteries (ASSLBs), single crystal NMC631 powder exhibits reduced capacity loss of 48%, attributed to improved interfacial stability.
