Improved Voltage and Cycling for Li+ Intercalation in High‐Capacity Disordered Oxyfluoride Cathodes
New high-capacity intercalation cathodes of Li2V x Cr1-x O2F with a stable disordered rock salt host framework allow a high operating voltage up to 3.5 V, good rate performance (960 Wh kg-1 at ≈1 C), and cycling stability.

متن کاملHigh capacity and exceptional cycling stability of ternary metal sulfide nanorods as Li ion battery anodes.
Ternary spinel NiCo2S4 nanorods are tested for the first time as anode electrodes for Li ion batteries. When the electrode is fabricated using the carboxymethyl cellulose-polyacryl amide composite binder, it is found to restrict or suppress the formation of a polymeric gel passivation layer. As a result, the electrode not only delivers excellent specific capacity, but also an outstanding rate a...
متن کاملCompatible interface design of CoO-based Li-O2 battery cathodes with long-cycling stability
Lithium-oxygen batteries with high theoretical energy densities have great potential. Recent studies have focused on different cathode architecture design to address poor cycling performance, while the impact of interface stability on cathode side has been barely reported. In this study, we introduce CoO mesoporous spheres into cathode, where the growth of crystalline discharge products (Li2O2)...
متن کاملHigh rate capability caused by surface cubic spinels in Li-rich layer-structured cathodes for Li-ion batteries
Modified Li-rich layered cathode Li(Li0.2Mn0.54Ni0.13Co0.13)O2 has been synthesized by a simple strategy of using surface treatment with various amounts (0-30 wt.%) of Super P (carbon black). Based on detailed characterizations from X-ray diffraction (XRD), high resolution transmission electron microscope (HRTEM), X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy...
