A Facile Chemical Reduction Approach of Li–Sn Modified Li Anode for Dendrite Suppression

Advanced Energy and Sustainability Research
Lithium dendrites are among the most significant threats associated with the practical application of lithium metal anode in lithium batteries. Lithium dendrites are caused by the slow Li‐ion diffusivity in the bulk lithium, which results in a non‐uniform electric field‐cum‐uneven Li plating/stripping at the electrode/electrolyte interface over ...

Bimetallic Nanoreactor Activates cGAS‐STING Pathway via mtDNA Release for Cancer Metalloimmunotherapy

Advanced Functional Materials, EarlyView.
A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Analysis of the Electrochemical Stability of Sulfide Solid Electrolyte Dry Films for Improved Dry‐Processed Solid‐State Batteries

Advanced Functional Materials, EarlyView.
An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

Dual‐Functional Additive Regulating Zn2+ Solvation Structure and (002) Plane‐Oriented Deposition for Dendrite‐Free Zn Anodes

Advanced Functional Materials, EarlyView.
Sulfosalicylic acid (SSA) is introduced as a bifunctional additive for Aqueous zinc‐ion batteries. SSA reconstructs the solvation structure of Zn2+ through the synergistic effects of its multiple functional groups, suppressing side reactions while selectively promoting Zn (002) deposition to prevent dendrite formation.

A Van der Waals Optoelectronic Synapse with Tunable Positive and Negative Post‐Synaptic Current for Highly Accurate Spiking Neural Networks

Advanced Functional Materials, EarlyView.
A van der Waals optoelectronic synaptic device based on a ReS2/WSe2 heterostructure and oxygen‐treated h‐BN is presented, which enables both positive and negative PSCs through photocarrier polarity reversal. Bidirectional plasticity arises from gate‐tunable band bending and charge trapping‐induced quasi‐doping.

A Single‐Metal‐Doped Nanoplatform for Ferroptosis‐Driven cGAS‐STING Pathway Activation in Hepatocellular Carcinoma Immunotherapy

Advanced Functional Materials, EarlyView.
The cGAS‐STING pathway boosts HCC antitumor immunity but lacks specific activation. Nanoplatform ZMRPF induces HCC ferroptosis via lipid ROS, releasing mtDNA. It synergizes with ZMRPF‐released Mn2⁺ to activate cGAS‐STING, amplifies antigen‐presenting cell activity, reverses HCC immunosuppression, and enables robust systemic antitumor immunity ...

Electrochemical Abuse‐Driven Thermal Runaway in Lithium‐Ion Batteries: Evolution From Beginning‐of‐Life to End‐of‐Life

Advanced Functional Materials, EarlyView.
Electrochemical abuse transforms thermal runaway behavior in lithium‐ion batteries. Through systematic decoupling of degradation mechanisms, this study reveals that lithium plating lowers the onset temperature by 10 °C, electrolyte consumption delays high‐temperature reactions, and capacity fade reduces total heat generation. These mechanistic insights
