    <title language="eng">Links Between Electrode Properties and  Cell Performance in Commercial  Sodium-Ion Batteries</title>
    <abstract language="eng">Our latest results of commercially purchased cylindrical sodium ion battery (SIB) cells will be presented. Two different cell types were dissasembled and thouroughly characterized on electrode as well as on material level.&#13;
Both cell types comprise aluminum current collectors for anode and cathode, respectively. Furthermore, geometric electrode parameters, such as electrode size, thickness and loading, will be presented and linked to the electrical data-sheet values. Further in-depth characterization on material level revealed that both cathode active materials are composed of a cobalt free Ni-Mn-Fe-oxide. Interestingly, the cathode particles significantly differ in shape and size between the two cell types. Both anode active materials are graphite-free, and the particle structure points in both cases to a biomass-derived hard carbon material. Based on gas chromatography mesaurements coupled with mass spectrometry (GC-MS), both cell types utilize a mixture of carbonates as electrolyte, however, contain different conductive salts. Moreover, the measured, characteristic electrical features, e.g., capacity, Coulombic efficiency, and initial cycle life, will be discussed. Intriguingly, the cycling stability greatly differs between the cell types. Presumably, this behaviour can be mainly linked to the different morphology of the cathode active material.&#13;
Overall, the work can give important insights in the composition and electrical behabiour of currently available SIB-cells.</abstract>

    <title language="eng">Linking material and electrode properties to the cell performance of commercially available sodium-ion cells</title>
    <abstract language="eng">As the first commercial sodium-ion-batteries (SIBs) are available for purchase, it is possible to investigate material composition. Gaining an insight into the material composition of these SIBs is of interest not only for the classification of possible safety risks and hazards, but also in regard to recycling. Herein we report the preliminary investigations of the chemical and structural composition of first commercial SIB-cells.[1,2] Two different SIB-cell types were compared in terms of electrode size, thickness, loading etc. Furthermore, the composition of the active materials and electrolyte was investigated and compared. Finally, the gained results were linked to the different data sheet performance of the two cell types.</abstract>
