Resolving Oxidative and Corrosive Calendar‐Aging via Electrolyte Engineering for Stable Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A weakly solvating ether solvent, 1,2‐dimethoxypropane (DMP), is proposed for use in localized high‐concentration electrolytes (LHCEs) for lithium metal batteries (LMBs). These DMP‐based LHCEs simultaneously suppress lithium metal corrosion and cathode degradation—two interrelated processes that accelerate calendar aging of LMBs.

Calendar effects in the Tunisian stock exchange

open access: yesInternational Journal of Behavioural Accounting and Finance, 2014
This paper examines daily returns of the stock market index of Tunisia (Tunindex) to prove whether there is existence of calendar effects related to the day of the week, the month of the year, and the semi–month effects. Using both parametric and nonparametric tests, we find evidence of day of the week and month of the year effects.

Sustainability Indices and the Calendar Effect

open access: yesFinance: Theory and Practice
The investing landscape has undergone a significant shift. Investors are interested in stocks that not only increase shareholder  wealth  but  also  give  high  priority to  environmental, social, and  governance  issues. The  purpose  of the study is to examine the  presence  of  a  calendar  effect  on  the  BSE  sustainability  indices.

Upscaling Sodium‐Ion Battery Cells: From Aqueous Processing to Performance Assessment of Hard Carbon|Prussian White Pouch Cells

open access: yesAdvanced Energy Materials, EarlyView.
This study investigates the feasibility of scaling up Prussian White (PW)‐based cathode manufacturing at a pilot scale. Through careful PW dehydration combined with optimized aqueous processing, we report the stepwise development of industrially relevant 1 Ah pouch cells and evaluate their performance under various conditions.

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Calendar Effect in The Chinese Securities Market

open access: yesBCP Business & Management, 2023
The existence of the calendar effect as a market anomaly problem proves that there are loopholes in the Efficient Market Hypothesis (EMH). By studying the calendar effect, scholars can gradually identify and solve the problems of regulatory loopholes and information asymmetry in the financial market.

Impact of Discharging Methods on Electrode Integrity in Recycling of Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Electrical and electrochemical discharge methods for end‐of‐life lithium‐ion batteries are compared. Electrochemical discharge better preserves the composition and layered structure of Ni‐rich cathode materials while minimizing residual lithium compounds.

Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...
