Impact of SEI Formation History on Lithium Metal Electrode Stability at Elevated Temperatures

Yutaro Goto, Yuki Miyaura, Takeru Hamada, Yuta Shiomi et autres

Solid electrolyte interphase (SEI) is critical for stabilizing lithium metal anodes, yet its evolution under thermal stress and the role of its formation history remain poorly understood. Here, lithium plating and stripping on Cu electrodes were investigated in 1.0 and 5.0 M …

Tuning the Sodium Electrode Potential by Solvent Molecular Framework Engineering

Hiroshi Takida, Yasuyuki Kondo, Tomoaki Kaneko, Keitaro Sodeyama et autres

Sodium-ion batteries (SIBs) are promising next-generation energy-storage systems, yet their low energy density remains a major challenge. An effective strategy to utilizing low-potential anodes is tuning their electrode potentials with respective to an electrolyte potential window. Herein we propose a molecular framework …

Solvent Molecule Decomposition at the Spinel Cathode Surface of Mg-Battery: A First-Principles Study

Keitaro Sodeyama, Tomoaki Kaneko, Yui Fujihara, Toshihiko Mandai et autres

Mg-based spinels (SP) such as MgM2O4 (M=Mn, Fe, Co) attract much interest as cathode material of future Mg-battery owing to those high capacities and high voltage. In the discharging process, Mg-based SP transforms into a rocksalt (RS) phase, MgM2O4 + Mg2+ + …

In-Service Childcare Workers’ Motivational Processes: Job Demands-Resources Model’s Job Demands

Tomoaki Kaneko, Chieko Kaneko, Yuno Shimizu

本研究の目的は，現職の保育者を対象に，ワーク・エンゲイジメントの仕事要求度-資源モデル（JD-Rモデル）に基づく動機づけプロセスとコーピング仮説を検証することであった。保育者283名を対象に，質問紙調査を行った。二次因子分析により仕事資源と個人資源の構造を特定した後，構造方程式モデリングを行った。その結果，仕事資源と個人資源は，ワーク・エンゲイジメントを介して情緒的コミットメントを高める動機づけプロセスが示された。さらに，仕事要求度の高群と低群ごとに多母集団同時分析を行った。その結果，仕事要求度に対するコーピングの効果は，想定した仕事資源および個人資源とワーク・エンゲイジメントの関連ではなく，仕事資源と情緒的コミットメントの関連において認められた。つまり，保育者のワーク・エンゲイジメントにおけるJD-Rモデルに関して，動機づけプロセスは全面的に，コーピング仮説は部分的に支持された。これらの結果を踏まえて，保育者の労働環境の構築や専門性の育成に向けた介入の方向性が議論された。

Distinct Differences in Li-Deposition/Dissolution Reversibility in Sulfolane-Based Electrolytes Depending on Li-Salt Species and Their Solvation Structures

Jiali Liu, Tomoaki Kaneko, Ji-young Ock, Shinji Kondou et autres

Herein, distinct differences in Li-deposition/dissolution reversibility were found in sulfolane (SL)-based electrolytes, depending on the Li-salt species and their solvation structures, owing to changes in the composition and nature of the solid-electrolyte interphase (SEI) and in the Li-deposit morphology. For this purpose, …
