TY - JOUR A1 - Böttcher, Nils A1 - Sander, Luise A1 - Ulbricht, Alexander A1 - Widjaja, Martinus Putra A1 - Fellinger, Tim-Patrick A1 - Schmidt, Anita A1 - Krug von Nidda, Jonas T1 - Sodium-ion battery research @ BAM (I): investigating the thermal runaway behaviour of commercial sodium-ion battery cells N2 - Commercially available sodium-ion battery (SIB) cells, with energy densities comparable to lithium-ion battery (LIB) cells based on LiFePO4, were investigated regarding their safety behaviour under thermal abuse conditions. Tests were carried out in an inert atmosphere. The SIB-cells went into thermal runaway (TR), intriguingly, even at a rather low state of charge of 30%. The TR-event was coupled with a pronounced jelly roll ejection, challenging the interpretation of the TR-diagrams. These findings highlight the necessity of incorporating SIB-cells into the ongoing safety classification discussions for LIB-cells.

Two different cell types were dissasembled and thouroughly characterized on electrode as well as on material level. 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. Overall, the work can give important insights in the composition and electrical behabiour of currently available SIB-cells.
