Commercially available 18650 Li-ion cells were exposed to charge-discharge cycling at 0°C using two different charging protocols: constant current-constant voltage (CC-CV) and constant current (CC). The effect of the charge process protocol on the L

Charge/discharge cycling tests of lithium-ion batteries were carried out at 1 °C. During cycling, the delivered capacity decreased substantially, just 30% of the capacity at 25 °C is retained after 45 cycles. The exothermic behavior of fresh and ag

Al doping into LiMn2O4 is one of the well-known methods to improve the cycle performance of the LiMn2O4 cathode. We carried out soft X-ray emission spectroscopy (XES) for LiMn2O4 and LiAl0.2Mn1.8O4 to elucidate the relationship between the Mn 3d elec

A through-focus series of annular bright field (ABF) images were observed simultaneously with high-angle annular dark field (HAADF) images of very thin lithium manganese oxide (LiMn 2 O 4 ), a typical cathode material used in lithium ion batteries, u

High-quality single crystalline LiMn2O4 nanowires, which can be synthesized by the conversion of Na0.44MnO2 nanowires, are promising electrode materials for high-power lithium ion batteries. Understanding the conversion mechanism is crucial for furth

© 2016 Author(s). We evaluate the utilities of fluorescence-yield (FY) modes in soft X-ray absorption spectroscopy (XAS) of several cathode materials for Li-ion batteries. In the case of total-FY (TFY) XAS for LiNi0.5Mn1.5O4, the line shape of the M
