Direct Synthesis of Single-Crystalline LiNi_0.8Co_0.1Mn_0.1O₂ Cathodes From Lithium-Containing Precursors via Spray Pyrolysis. [PDF]

Small Sci
A novel strategy for the direct synthesis of single‐crystalline LiNi0.8Co0.1Mn0.1O2 cathodes via spray pyrolysis is introduced, delivering stable cycling performance. Spray pyrolysis enables the synthesis of Li‐containing precursors and allows short‐duration calcination without additional Li mixing.
