Neutron Science 085 scNMC811/LZC cell is shown in Figs. 3(b) and 3(c) ; the average discharge capacities at 0.2 and 2 C are 176 and 96 mA h g –1 , respectively. The long-term cycling data is displayed in Fig. 3(d) , which demonstrates Coulombic efficiency 99.9% and discharge capacity 149 mA h g –1 after 200 cycles at 1 C. According to the scanning electron microscope and XRD ex situ , the positive electrode and solid electrolyte were still in intimate contact with each other without noticeable reaction or inter- diffusion after prolonged cycling. Ma and his co-workers discovered as-milled LZC as a new solid-state electrolyte that might possess the advantages of greater tolerance to humidity and lower cost for the raw materials.
