摘要:Abstract(#br)We use confocal μ-Raman spectroscopy to characterize the local microstructure of SiO x particles that are composed of amorphous and crystalline phase and to understand its effects on electrochemical reactions. Particles of bare SiO x (x ∼ 1) consist of an inhomo...

摘要:Abstract(#br)To quantify the effect of high voltage on the electrochemical properties of high-potential spinel ordered-LiNi 0.5 Mn 1.5 O 4 , it was intentionally exposed to 5.3 V for 100 h that can ensure the decomposition of electrolyte. After this treatment, the bulk struc...

摘要:Abstract(#br)Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) is a promising solid electrolyte for all-solid-state Li ion batteries. In this work, it was synthesized using solid-state reaction with an excess amount of Li to improve grain boundary ionic conductivity. The additional Li i...

摘要:Abstract(#br)To understand the delithiation behavior of particles of different sizes, we developed a centrifugation method to separate particles in a chemically-delithiated Li 0.49 FePO 4 with respect to their size. Small particles were obtained at high centrifuge speed whereas l...

摘要:Abstract(#br)Understanding of the fundamental mechanisms causing significant enhancement of Li-ionic conductivity by Al 3+ doping to a solid LiGe 2 (PO 4 ) 3 (LGP) electrolyte is pursued using first principles density functional theory (DFT) calculations combined with experi...

摘要:Abstract(#br)To the best of our knowledge, this is first report about composite of perovskite materials and reduced graphene oxide as anode material for high performance lithium ion battery (LIB). Here, we report outstanding specific capacities and cyclic stabilities of pero...

摘要:Abstract(#br)We present an analysis of the thermal reduction of delithiated LiMnPO 4 and LiFePO 4 based on the quarternary phase diagrams as calculated from first principles. Our results confirm the recent experimental findings that MnPO 4 decomposes at a much lower temperature t...
