The influences of Ni/Mn disordering on the physical properties and electrochemical performance of the truncated octahedral LNMO samples have been systematically investigated. The analyses of thermogravimetry, X-ray photoelectron spectroscopy, X-ray diffraction, powder neutron diffraction, Raman spectroscopy and X-ray absorption spectroscopy reveal that the occurrence and degree of Ni/Mn disordering are closely related with the formation of oxygen vacancies and presence of Mn3+. Slow cooling rate and post-annealing can result in low degrees of Ni/Mn disordering and oxygen vacancies. Electrochemical measurements show that Ni/Mn disordering and oxygen vacancies have no obvious effect on the rate capability since all LNMO samples share a truncated octahedral morphology with the exposed {100} surfaces. However, they play significant roles in improving long-term cycling stability, especially at the elevated temperature of 60°C. This work suggests that the electrochemical performance of LNMO with optimized truncated morphology can be further enhanced through tuning the degrees of Ni/Mn disordering and oxygen vacancies. 000863205 536__ $$0G:(DE-HGF)POF3-131$$a131 - Electrochemical Storage (POF3-131)$$cPOF3-131$$fPOF III$$x0 000863205 588__ $$aDataset connected to CrossRef 000863205 7001_ $$0P:(DE-HGF)0$$aZhang, Xiaofei$$b1 000863205 7001_ $$0P:(DE-Juel1)169319$$aHe, Xin$$b2$$ufzj 000863205 7001_ $$00000-0002-1473-8992$$aSenyshyn, Anatoliy$$b3 000863205 7001_ $$0P:(DE-HGF)0$$aWilken, Andrea$$b4 000863205 7001_ $$0P:(DE-HGF)0$$aZhou, Dong$$b5 000863205 7001_ $$0P:(DE-HGF)0$$aFromm, Olga$$b6 000863205 7001_ $$0P:(DE-HGF)0$$aNiehoff, Philip$$b7 000863205 7001_ $$0P:(DE-Juel1)169694$$aYan, Bo$$b8$$ufzj 000863205 7001_ $$0P:(DE-Juel1)169876$$aLi, Jinke$$b9$$ufzj 000863205 7001_ $$0P:(DE-HGF)0$$aMuehlbauer, Martin$$b10 000863205 7001_ $$0P:(DE-Juel1)168392$$aWang, Jun$$b11 000863205 7001_ $$0P:(DE-HGF)0$$aSchumacher, Gerhard$$b12 000863205 7001_ $$0P:(DE-Juel1)166311$$aPaillard, Elie$$b13$$ufzj 000863205 7001_ $$0P:(DE-Juel1)166130$$aWinter, Martin$$b14$$ufzj 000863205 7001_ $$0P:(DE-Juel1)174577$$aLi, Jie$$b15$$eCorresponding author$$ufzj 000863205 773__ $$0PERI:(DE-600)2002179-3$$a10.1149/2.1241809jes$$gVol. 165, no. 9, p.
