(Invited) Single Crystal Ni-Rich Cathode Materials: Synthesis, Scaleup and Validation

This talk will discuss an innovative but cost-efficient synthesis of high-performance single crystal NMC811 that is enabled by a new lithium salt, readily adaptable for industry manufacturing. The reaction mechanism of single crystal growth is investigated to understand the fast growth mechanism of single crystalline NMC811. The scaled single crystal NMC811 is further validated in a >1Ah Li-ion pouch cells, demonstrating excellent cycling, confirming the feasibility of this scalable synthesis approach. This work provides new insights on utilizing salts to simplify manufacturing process of cathode materials that are broadly applicable for cost-efficient large-scale synthesis of single crystals for different advanced battery technologies for broad applications.
