All synthesized materials show a well-defined layered structure of the hexagonal α-NaFeO2 phase (space group Rm) analyzed by X-ray diffraction (XRD). Electrochemical Li-metal/cathode cell studies exhibit that a Sn-content of $1\%–2\%$ is beneficial regarding specific discharge capacity and cycle life $(≥20\%).$ Detailed electrochemical investigations of Li-metal and lithium ion cells with cathodes consisting of LiNi0.6Mn0.2Co0.2O2 and LiNi0.6Mn0.2Co0.18Sn0.02O2 are conducted. Post mortem analyses by means of ICP-OES and TXRF show beneficial effects of the Sn-doping with regard to a lower transition metal dissolution and a higher available Li content in the cathode active material. The thermal analyses (TGA, DSC, ARC) show a stabilizing effect of Sn-doping, which results from a lower mass loss and less heat evolution of the charged cathode active materials at elevated temperatures.}, cin = {IEK-12}, ddc = {620}, cid = {I:(DE-Juel1)IEK-12-20141217}, pnm = {131 - Electrochemical Storage (POF3-131)}, pid = {G:(DE-HGF)POF3-131}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000445317900010}, doi = {10.1016/j.jpowsour.2018.06.072}, url = {https://juser.fz-juelich.de/record/865961}, }
