PHASE diagram equilibrium studies in the binary tungsten–rhenium system show the presence of two phases over the range 0–65 wt. per cent rhenium at 1,500° C (ref. 1). A terminal solid ...

This study proposes a lithium-induced grain boundary phase W doping mechanism. To enhance the cycling stability of LiNiO2, the Li2WO4 grain boundary phase with excellent lithium-ion conductivity ...
