Control of Equilibrium Potential for Li-Naphthalenide Solution and Its Application to Si-Based Anodes for Next-Generation Batteries
Get PDFIn recent years, new-generation batteries such as Li-S and Li-O2 systems have been strongly demanded for the power source of electric vehicles (EVs). These systems possess excellent potentials for the higher energy densities beyond the conventional Li-ion batteries. Li metal was basically used as the negative electrode (NE) owing to the high theoretical capacity (3860 mAh g-1). However, this causes the risk of short-circuit by Li dendrite growth during charge/discharge cycling. Si is a good alternative to Li metal NE because of the comparable high theoretical capacity (3580 mAh g-1) and the difficulty of Li dendrite growth. In the practical use, it is necessary to Li pre-dope, i.e. Li-Si alloying, to apply the Si NEs to such next-generation batteries. On the other hand, advanced Li secondary batteries using Li containing positive electrode (PE) also need high capacity NEs such as SiO cancelling a large irreversible capacity at the 1st charging. For these purposes, we have studied a solution-type Li pre-doping technique using Li-naphthalenide (Li-NTL) solutions. In this study, two different approaches: effects of (1) Li concentration and (2) the kinds of solvents were investigated on the equilibrium potential of Li-NTL solutions and the depth of Li alloying toward Si and SiO NEs. To deeply clarify the factor of controlling the equilibrium potential of the Li-NTL solution, the kinds, generation amounts and solvated structures of NTL anions (monoanion radical NTL•– and dianion NTL2–) were also evaluated and analyzed in detail.departmental bulletin pape
Practices of SDGs and ESD for a Sustainable Society
Get PDF本稿は2024 年9 月27 日に成蹊大学で実施された武蔵野市寄附講座「ローカルな場で考える持続可能性」（コーディネーター：小田宏信）第2 回での鈴木克徳氏の講演内容を編集の上，収録したものである。SDGs（持続可能な開発目標）という概念が，2015 年に現れて，当初の2 年ほどはほとんど浸透することがなかったが，今日，10 年近くたって，少なくとも用語としては日本社会に浸透してきている。しかし，SDGs の狙いが何なのかというと，正確に答えられる人というのはそう多くない。また，SDGs よりも先んじてESD （持続可能な開発のための教育） という概念があった。ESD は，日本政府が世界に対して提唱して，進めてきた一つの教育運動であるが，一般社会ではほとんど知られていない。鈴木氏は，日本におけるESD の活動の大黒柱としてご活躍で，成蹊学園サステナビリティ教育研究センターの発足にあたっても有益なアドバイスをいただいたという経緯がある。同日の講演では，改めてSDGs とは何なのか，どのような狙いがあるのか，そしてその実現のために社会もしくは個人ができることは何なのかということを中心にお話し頂いた。departmental bulletin pape
