Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

open access: yesAdvanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Magmatic Controls on Au- and Ag-Rich Intermediate-Sulfidation Epithermal Deposits from Northeast China

open access: yesEconomic Geology
Abstract Intermediate-sulfidation epithermal deposits are important not only for their significance in terms of Ag endowment but also for their close link with porphyry deposits. There are two subtypes of intermediate-sulfidation deposits, namely Au-rich (Ag/Au <60) and Ag-rich (Ag/Au >60).

Tsav: A shoshonite-hosted intermediate sulfidation epithermal Ag-Pb-Zn deposit, eastern Mongolia

2005
Epithermal Ag-Pb-Zn mineralization at the Tsav deposit, Eastern Mongolia is characterized by intermediate sulfidation state mineral assemblages, and is hosted by shoshonitic volcanic rocks. Hydrothermal alteration varies from propylitic to argillic. Galena, sphalerite and silver form the ore mineral association.

Recently-discovered Bahçecik Au±Ag mineralization in the Eastern Pontides, Gümüşhane-NE Türkiye: geological and geochemical implications on the intermediate sulfidation epithermal deposit

open access: yesInternational Geology Review, 2023
Intermediate sulfidation epithermal deposits represent significant reservoirs of precious metals, playing a crucial role in global mining operations. The Anatolian Peninsula, predominantly characterized by relatively young (Tertiary) lithologies, hosts ...
