Impurity Tolerance in LiFePO4 Cathodes: Contrasting Structural, Electronic, and Electrochemical Roles of Residual Ni and Cr

open access: yesAdvanced Science, EarlyView.
Impurity tolerance in LiFePO4 cathodes varies strongly with impurity type and content. Low Ni levels are accommodated within the lattice with minimal structural disruption, whereas higher Ni contents introduce antisite disorder. In contrast, Cr impurities segregate from the LiFePO4 framework, blocking lithium‐ion pathways and leading to inferior ...

Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium

open access: yesAdvanced Science, EarlyView.
A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and dislocations to blunt crack tip.

Efficient Direct Recycling of Spent Batteries: Integrated Lithiation and Delamination

open access: yesAdvanced Science, EarlyView.
An integrated process for the delamination and relithiation of spent cathodes, LixNi0.6Co0.2Mn0.2O2 and LixFePO4, under open‐air conditions is proposed. The transition‐metal (Ni) oxidation state in the cathode is reduced by the oxidation of diethylene glycol, facilitating relithiation. Glycol aldehyde formation induces 100% electrode delamination.

Deep Eutectic Polymer Electrolyte with Competitive Hydrogen‐Bonding Coordination for High‐Voltage Nickel‐rich Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
To stabilize high‐voltage Li||NCM811 batteries, we develop an in situ polymerized deep‐eutectic electrolyte (p‐DEPE) featuring competitive hydrogen‐bonding coordination. This design weakens Ni4+ adsorption, suppresses oxygen release, and enhances interfacial stability.

Beyond d‐Band Catalysis: A Critical Review and Descriptor Framework for Rare‐Earth Engineering in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework
