Interplay of Inhomogeneous Electrochemical Reactions with Mechanical Responses in Silicon-Graphite Anode and its Impacts on Degradation
Junhyuk Moon, Shinya Wakita, Heechul Jung +8
Enhanced EV market penetration requires durability of the battery with high energy throughput. For long-term cycle stability of silicon-graphite anode capable of high energy densit…
Spontaneous and mass-conserved formation of continuous Si frameworks
K. Ogata, D. -S. Ko, C. Jung +18
Controlled formation of porous silicon has been of primary importance for numerous landmark applications such as light emitting sources, sensors, actuators, drug delivery systems,…
Revealing evolving affinity between Coulombic reversibility and hysteretic Li-Si phase transformations
Ken Ogata, Seongho Jeon, Dong-Su Ko +17
Nano-structured silicon anodes are attractive alternatives to graphite in Li-ion batteries. Despite recent remarkable progresses in numerous Si-C composites, the commercialisation…
Carrier-Induced Magnetic Circular Dichloism in the Magnetoresistive Pyrochlore Tl2Mn2O7
H. Okamura, T. Koretsune, S. Kimura +4
Infrared magnetic circular dichloism (MCD), or equivalently magneto-optical Kerr effect, has been measured on the Tl2Mn2O7 pyrochlore, which is well known for exhibiting a large ma…
Large Thermoelectric Power Factor in TiS2 Crystal with Nearly Stoichiometric Composition
H. Imai, Y. Shimakawa, Y. Kubo
A TiS crystal with a layered structure was found to have a large thermoelectric power factor.The in-plane power factor at 300 K is 37.1~W/Kcm with resisti…
Charge Dynamics in the Colossal Magneto-Resistance Pyrochlore Tl2Mn2O7
H. Okamura, T. Koretsune, M. Matsunami +5
Optical conductivity data s(w) of the colossal magneto-resistance (CMR) pyrochlore Tl2Mn2O7 are presented as functions of temperature (T) and externalmagnetic field (B). Upon cooli…
