Multiscale Design of Anion Exchange Membrane‐Based Seawater Electrolysis for Sustainable Hydrogen Production

open access: yesAdvanced Energy Materials, EarlyView.
Direct seawater electrolysis using anion exchange membranes is emerging as a promising route for sustainable hydrogen production. This review summarizes multiscale design strategies from seawater chemistry and OER–ClER selectivity to catalysts, membranes, MEAs, cells, stacks, and system integration, providing a roadmap toward selective, durable, and ...

A Fluorine‐Free, Low Ion Pair Electrolyte for Transition Metal‐Free and Halogen‐Free Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Fluorine‐containing electrolytes dominate modern rechargeable batteries, yet the fundamental design principles for fluorine‐free systems remain largely unexplored. We demonstrate that fluorine‐free electrolyte chemistry can simultaneously achieve long cycle life, fast charging, and stable interphase formation in sodium‐ion batteries.

Nanocrystalline LCO/LLZO Composite Cathode Films for Solid State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A single precursor solution is solution‐deposited and calcined at only 750°C to yield a dense, nanograined LiCoO2/LLZO composite cathode, in which both phases crystallize independently with minimal interdiffusion. Assembled into all‐solid‐state Li‐metal batteries, the composite delivers 111.7 mAh g−1 initial discharge capacity and retains 93% after 100

On the payment system in Japan and payment risk

open access: yesOn the payment system in Japan and payment risk
2007年夏のサブプライムローン問題の発生以降,国際金融市場では緊張感が高まり,2008年9月のリーマン・ブラザーズの破綻をきっかけに,さらに大きく動揺した。わが国においても,リーマンショックの発生に伴い,多額の決済不履行が発生した。こうしたなか,金融危機の発生に伴うショックを柔軟に吸収しうる頑健性の高い決済システムの構築が求められていることは,いうまでもないであろう。本論は,近年,急激にその取引量を拡大しているわが国決済システムの制度・機能を近時の制度変化に言及しながら概括し,決済システムの効率性並びに安全性の両面における課題を把握することを目的としている。本論ではまず,決済システムの経済機能の解説を与え,さらに本論文で考察の対象とするわが国資金決済システムにおける近年の変化を詳しく述べた後 ...
