Hollow multishelled structures revive high energy density batteries
Hollow structures have been shown to be fruitful in addressing the cycling-stability problem of high-capacity electrode materials. However, we have noticed that there exist misconceptions toward the energy density of hollow-structured electrodes. In this Focus Article, the indispensability of hollow structures for stable high energy density batteri...

Preparation of LiNi0.8Co0.1Mn0.1O2 cathode materials from the hydrochloric acid leaching of laterite: A short and low-co...
The direct preparation of LiNi0.8Co0.1Mn0.1O2 (LNCM811) cathode materials from the hydrochloric acid leaching of laterite are promising; however, there are Cl- ions and other impurities in the hydrochloric acid leaching solution, thereby limiting the commercial application of LNCM811. In this study, we compared the LNCM811 prepared from Cl-- and SO...

Chemical trends in the lattice thermal conductivity of Li(Ni, Mn, Co)O-2 (NMC) battery cathodes
While the transport of ions and electrons in conventional Li-ion battery cathode materials is well understood, our knowledge of the phonon (heat) transport is still in its infancy. We present a first-principles theoretical investigation of the chemical trends in the phonon frequency dispersion, mode lifetimes, and thermal conductivity in the series...
Revisiting of Tetragonal NaVPO4F: A High Energy Density Cathode for Sodium-Ion Batteries
Tetragonal NaVPO4F has been regarded as an ideal cathode for sodium-ion batteries because of its high average plateau (3.8 V) and theoretical specific capacity (143 mA h g(-1)). However, the Na-storage performance is still hindered by unsatisfying thermal stability and poor conductivity. Herein, a stable tetragonal NaVPO4F has been synthesized by a...

The origin of chemical inhomogeneity in garnet electrolytes and its impact on the electrochemical performance
The interface between solid electrolytes and lithium metal electrodes determines the performance of an all-solid-state battery in terms of the ability to demand high power densities and prevent the formation of lithium dendrites. This interface depends strongly on the nature of the solid electrolyte surface in contact with the metallic anode. In th...
One-Step Synthesis of Carbon-Coated Na-3(VOPO4)(2)F Using Biomass as a Reducing Agent and Their Electrochemical Properti...
In this work, a one-step hydrothermal strategy has been developed for the synthesis of carbon-coated Na-3(VOPO4)(2)F with the aid of biomass (e.g. glucose, fructose or starch), where biomass plays the key role of carbon source and reducing agent for reducing vanadium(V) to vanadium(IV). The effect of different biomass on the morphologies has been e...
