The structural relaxation analysis has been carried out on LixNi0.8Co0.1Mn0.1O2 (NCM-811) and LixNi0.55Co0.20Mn0.25O2 (NCM-552025) after the lithium extraction at 0.1 C-rate to the high-voltage region (x ≤ 0.12). For NCM-811, the H3 phase appeared

Abstract Lead acid battery has been one of the most important battery for industry use. However, conventional lead acid battery cannot be recharged after over discharge and the performance is greatly declined. It has been revealed that the cause of n

We have previously reported that a three-fold increase in lithium-ion conduction can be achieved on LATP (Li1.3Al0.3Ti1.7(PO4)3) by dispersing LaPO4 particles through the co-sintering of LATP with 4 wt% of LLTO (Li0.348La0.55TiO3). However, the LaPO4

Relaxation analysis has been carried out on fresh and charge-discharge cycled graphites to evaluate the effect of cycle process on the relaxation behavior after lithium insertion. While the formed stage I at charging partly transforms into stage II d

To clarify the contribution of defect structure of CaWO4-based system on the oxide ion conduction properties, we doped both cesium and lanthanum ions into CaWO4 as Ca0.9CsxLa0.1−xWO4.05−x. Scheelite-type structured solid solution can be obtained

LATP-based composite electrolytes were prepared by sintering the mixtures of LATP precursor and La2O3 nano-powder. Powder X-ray diffraction and scanning electron microscopy suggest that La2O3 can react with LATP during sintering to form fine LaPO4 pa

In our recent study, we aimed to impart hydroxyapatite (HA)-forming to bioinert stainless steels (SUS316L). The surfaces of SUS316L specimen were treated by a sandblasting process using alumina grinding particles with 14.0 or 3.0 μm for average part

A structural relaxation study has been carried out on Lix(Ni0.874Co0.090Al0.036)O2 after the electrochemical lithium was extraction down to x = 0.12. These relaxation analyses have been carried out using X-ray diffraction coupled with the Rietveld an

We have prepared Ca1−xKxWO4−x/2 solid solutions with the Scheelite-type structure to investigate high-temperature electrochemical properties. Room-temperature X-ray diffraction suggested the solid solution range was x ≤ 0.2, since the second ph
