Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Titanium (Ti)–steel composite joints are prone to the formation of compounds such as TiC, TiFe, and TiFe2 during solid‐phase bonding. This phenomenon leads to premature failure and significantly reduces the bonding quality of the joints. However, the fracture behavior of the joint influenced by these compounds, particularly on the initiation ...
