We report on the highly stable lithium metal vertical bar LiNi0.8Co0.1Mn0.1O2 (NCM 811) cells with practical electrodes loading of 3.4 mAh cm(-2), lowamount of electrolyte solution comprising 1MLiPF(6) in fluoroethylene carbonate (FEC)/dimethyl carbonate (DMC), around 1-1.5 mu Lm(g-)1 of active cathode material (22-33 mu Lcm(-2)) and current density of 1 mAcm(-2) both at 30 degrees C and elevated temperatures (45-55 degrees C). TheNCM811 cathodes and Li metal anodes were characterized by X-ray diffraction, SEM and Fourier transform infrared spectroscopy. We demonstrate that the cathodes' active mass preserves its crystal structure and particles morphology without any signs for cracks formation both after cycling with FEC and EC based electrolyte solutions. The limiting factor for stable cycling of Li vertical bar NCM 811 cells is the formation of thick resistive films on the surface of Li anodes which is highly dependent on the electrolyte solutions' composition.
