Rate capability of carbon-free lithium titanium oxide electrodes related to formation of electronic conduction paths observed by color change

Autor: Yusuke Yamada, Takaya Ino, Kingo Ariyoshi

Publikováno v: Journal of Power Sources. 430:150-156

Lithium titanium oxide prepared by the hydrogen reduction synthesis of Li[Li1/3Ti5/3]O4 (LTO) exhibits electronic conductivity. The product demonstrated a superior rate capability than pristine LTO upon the examination of a pellet electrode in the ab

Li2Ni0.2Co1.8O4 having a spinel framework as a zero-strain positive electrode material for lithium-ion batteries

Autor: Kensuke Kajikawa, Kingo Ariyoshi, Yuki Orikasa, Yusuke Yamada

Publikováno v: Journal of Materials Chemistry A. 7:13641-13649

Zero-strain insertion materials are ideal electrode materials for lithium-ion batteries because they do not undergo dimensional change during lithium insertion and extraction. Herein, a zero-strain insertion material, Ni-substituted Li2Co2O4 (Li2Ni0.

High dimensional stability of LiCoMnO4 as positive electrodes operating at high voltage for lithium-ion batteries with a long cycle life

Autor: Hiroya Yamamoto, Yusuke Yamada, Kingo Ariyoshi

Publikováno v: Electrochimica Acta. 260:498-503

Dimensionally stable LiCoMnO4 having a spinel-framework structure was developed as a positive electrode of lithium-ion batteries with a long cycle life. Well-crystallized LiCoMnO4 prepared by a two-step solid-state reaction shows large rechargeable c

Impact of particle size of lithium manganese oxide on charge transfer resistance and contact resistance evaluated by electrochemical impedance analysis

Autor: Yusuke Yamada, Kingo Ariyoshi, Masumi Tanimoto

Publikováno v: Electrochimica Acta. 364:137292

To achieve high-power lithium-ion batteries, resistances of both positive and negative electrodes must be reduced, because these are the main sources of internal resistance of the batteries. It is necessary to elucidate the impact of physicochemical

Self-discharge tests to measure side-reaction currents of a Li[Li_1/3Ti_5/3]O_4 electrode

Autor: Yusuke Yamada, Takahide Toda, Kingo Ariyoshi

Publikováno v: Journal of Electroanalytical Chemistry. 864:114110

The lifetime performance of lithium-ion batteries is a critical issue for automobile and stationary applications. The difference in the side-reaction current (ISR) of electrodes causes deviations of the state of charge (SOC) of the electrodes leading

Examining the Long-Term Cyclabilities of Li[Ni_1/2Mn_3/2]O_4 and Li[Li_0.1Al_0.1Mn_1.8]O_4 Using a Full-Cell Configuration Including LTO-Counter Electrodes with Extra Capacity

Autor: Kingo Ariyoshi, Motoyuki Hirooka, Makoto Eguchi

Publikováno v: Journal of The Electrochemical Society. 167(6):060532

In this study, a novel cell configuration was developed for evaluating the cyclabilities of lithium insertion materials. In this cell, the Li[Li_1/3Ti_5/3]O_4 (LTO) counter electrode has excess capacity on both the charge and discharge sides (EQ-LTO)

Elucidation of the origin of voltage hysteresis in xLi2MnO3∙(1−x)LiCoO2 using backstitch charge-discharge method

Autor: Kingo Ariyoshi, Yusuke Yamada, Takayuki Inoue

Publikováno v: Electrochimica Acta. 334:135623

Lithium-excess (LEX) materials with a composition of xLi2MnO3∙(1−x)LiMO2 (M = Fe, Co, or Ni) exhibit large reversible capacities and are therefore promising positive electrode materials for Li-ion batteries. However, the widespread application of
