N1 - Funding Information:
We wish to acknowledge the Diamond Light Source, UK (proposal NR19772), and Karlsruhe synchrotron light source KARA for the provision of beamtime. Part of this research was also carried out on the powder diffraction beamline at the Australian Synchrotron, ANSTO, and at the Department of Applied Biology and Chemical Technology, The Hong Kong Polytechnic University. Financial support was provided by the Federal Ministry of Education and Research (BMBF) under funding number 03XP0231, by the Diamond Light Source (DLS, UK) Year in Industry Studentship Programme,the Faraday Institution (faraday.ac.uk; grant numbers FIRG001, FIRG011, FIRG020), the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (EXISTAR, grant agreement No. 950598).

N2 - The syntheses of Ni-poor (NCM111, LiNi1/3Co1/3Mn1/3O2) and Ni-rich (NCM811 LiNi0.8Co0.1Mn0.1O2) lithium transition-metal oxides (space group R3̅m) from hydroxide precursors (Ni1/3Co1/3Mn1/3(OH)2, Ni0.8Co0.1Mn0.1(OH)2) are investigated using in situ synchrotron powder diffraction and near-edge X-ray absorption fine structure spectroscopy. The development of the layered structure of these two cathode materials proceeds via two utterly different reaction mechanisms. While the synthesis of NCM811 involves a rock salt-type intermediate phase, NCM111 reveals a layered structure throughout the entire synthesis. Moreover, the necessity and the impact of a preannealing step and a high-temperature holding step are discussed.
