The morphology and microstructure of precursors are the key to preparation high-quality NCM cathodes due their inheritance relationship. However, a large amount sulfate exists in precursors, detriment electrochemical performance Ni-rich cathode materials. Herein, an effective method for reduction was proposed synthesis Ni0.90Co0.05Mn0.05(OH)2 precursor by adding 0.24 M ammonia microreactor. less Ni(OH)2 with system is attributed higher formation energy adsorption (ENi(OH)2-am-SO42– = 7.483 eV vs ENi(OH)2-SO42– 3.451 eV). results demonstrated that can promote growth primary particles (81.5 nm) reduce content impurity from 0.80 0.28% precursors. Moreover, prepared materials exhibit high specific capacity 190.4 mAh g–1 at 1C superior Li+ diffusion coefficients. This study sheds light on role rapid coprecipitation provides guidance process cathodes.

Although layered oxides of LiNixCoyMnzO2 (NCM, x + y z = 1) are promising high energy density cathode materials, they still face significant challenges such as the cracks caused by anisotropic strain and poor structural thermal stability upon building high-performance rechargeable lithium-ion batteries (LIBs) for scale-up industrialization. Under this circumstance, La Mg elements theoretically experimentally introduced into NCM to modify primary particles synergistically lattice orientation regulation surface perovskite-phase coating. The synthesized La/Mg co-doped delivers a discharge-specific capacity 203 mAh g-1 at 0.1 C 126.2 10 (1C 200 mA g-1), which results from radial grain incorporating trace amount dopants, well enhancements on both ionic electronic conductivities. Further analysis discloses formation La-based perovskite protective layer surface, plays key role in stabilizing oxygen ions cycling increasing stabilities cathode. This one-step co-doping strategy provides rewarding avenue toward developing practical cathodes high-performance, durable Li batteries.

The practical application of nickel-rich layered transition metal oxide is hampered by its fast capacity decay, deriving from the side reactions with electrolyte, crack formation caused volume variation, and phase change near surface during charging/discharging processes. Here, we experimentally realize mechano-chemo-electrochemical coupling effect nanolayer on to greatly improve electrochemical performance. According detailed atomic structure analysis, this facilitates consuming residual lithium left oxide, suppressing reducing due variation long-term cycles. This design plays an in mechanical, chemical, aspects simultaneously which beneficial for their development.
