Ni‐rich layered oxides (LiNi 1– x M O 2 ; = Co, Mn, …) are appealing alternatives to conventional LiCoO as cathodes in Li‐ion batteries for automobile and other large‐scale applications due their high theoretical capacity low cost. However, preparing stoichiometric LiNi with ordered layer structure reversible capacity, has proven difficult cation mixing octahedral sites. Herein, situ studies of synthesis reactions the associated structural ordering LiNiO Co‐substituted variant, 0.8 Co 0.2 ,...
A new approach to intentionally induce phase transition of Li‐excess layered cathode materials for high‐performance lithium ion batteries is reported. In high contrast the limited layered‐to‐spinel transformation that occurred during in situ electrochemical cycles, a Li[Li 0.2 Mn 0.54 Ni 0.13 Co ]O 2 completely converted Li 4 5 O 12 ‐type spinel product via ex ion‐exchanges and post‐annealing process. Such conversion examined using X‐ray diffraction high‐resolution transmission electron...

In this article, pseudo-binary Cr-MoNbTaVW phase diagram presented show impact of content senary system; sub-lattice site fractions are disordered property BCC structures; equilibrium and Scheil solidification results with actual sample elemental compositions thermodynamic information melted/solidified samples; raw EDS scan arc-melted samples also provided.
Jinan City in China is known for its abundant spring water, and the protection of underground water transport channels a key issue that needs to be paid attention subway construction. In areas where are easily disturbed, when shield tunnel passes through composite formation with permeable layer middle an impermeable upper lower parts, transportation channel blocked, veins damaged, blocked upstream, resulting increase pressure difference on both sides tunnel. this paper, based working...
During the process of rapid cooling, two distinct types supercooled liquids are found. One kind destines to crystallize (the crystal-forming liquid (GFL)), and other forms a glass glass-forming (GFL)). Despite having no significant differences in conventional physical quantities such as structure energy, distribution potential energy after short-time averaging reveals emergence distinction. By analyzing skewness average, new characteristic time ($\Delta_{CTS)}$) emerges. For given...
