Monoclinic structure, C2 / c space group, Li2-XRuO3 has about 1 lithium ion that can be de-intercalated. With Ru5 and Ru4 reactions, 3.6V and 3.4V each have a platform, 3.6V corresponds to 0.7 <x < 1.0. There are two platforms at 4.15V and 4.6V for further charging.

    With the increase of the electrical conductivity of the lithium-ion batteryEnergy storage lithium battery. At 293K, the specific resistances at X = 0, X = 0.7, and X = 1.0 were 9.99Ω · cm, 0.507Ω · cm, and 0.769Ω · cm, respectively. The structure of Lin3 ~ 1.4RuO3 is the same as that of Li2RuO3. The structure of Li0.9 ~ 1.0RuO3 has evolved into R-3 rhombobedral structure. After the lithium ions in the lithium layer are removed, O will change from cubic meters to hexagonal close-packed. Li3PO4 surface modified nano-Li2RuO3 surface formed a 3.6nm-thick amorphous Li3PO4 layer, the substrate is pulsed laser-deposited 25.5nm-thick Li2RuO3, 2μA / cm2 and 2.8 ~ 4.2V for the first charge capacity of 296mA · h / g. The comparative sample is 190mA · h / g. Surface modification can enhance the stability of the structure。

   shows the cyclic voltammetry curve measured at 0.3mV / s in the Li2RuO3 / Li3PO4 solid electrolyte system. The two pairs of redox peaks correspond to the equilibrium potentials of approximately 3.65V and 3.45V, respectively, and the corresponding reduction peaks are at 3.6V and 3.3V. The oxidation / reduction peak is relatively obvious, indicating that the corresponding potential platform is relatively flat; from the charge and discharge curve, the reaction mechanism represented by each potential platform is a two-phase equilibrium mechanism.

    During the first charge, the structure evolved from C / 2C to R-3. With the deformation of RuO6, further charging caused the structure to lose some oxygen, and the degree of RuO6 deformation was reduced, forming A new phase cannot be determined at present; if the discharge is accompanied by the re-intercalation of lithium ions, a poorly crystalline original phase is formed, but the composition is slightly different,which can be expressed as Li1.9RuO3-y.
