TL;DR: In this article, a novel lithium-rich Li1.86O2 microsphere with heterogeneous distribution in the composition has been reasonably designed and successfully synthesized via a co-precipitation method.

TL;DR: In this paper, the chemical diffusion coefficients of lithium ions in spherical Li[Ni 0.5 Mn 0.3 Co 0.2 ]O 2 are systematically determined by GITT and electrochemical impedance spectroscopy (EIS).

TL;DR: Li et al. as discussed by the authors synthesized LiFePO 4 /C composites by a simple high-temperature solid-state route and characterized the structure, morphology and electrochemical performance of the samples.

TL;DR: In this article, the kinetics of Li-ion deintercalation in Li 1.89 O 2 samples are studied by electrochemical impedance spectroscopy (EIS) and galvanostatic intermittent titration technique (GITT) during the first charge process.

TL;DR: In this paper, the structure, morphology and electrochemical performance of the LiFePO 4 /C composites were characterized by X-ray diffraction (XRD), Xray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), charge/discharge tests, electrochemical impedance spectrograph (EIS) and galvanostatic intermittent titration technique (GITT).
