A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.

In situ cryogenic STEM‐EELS and electron diffraction directly visualize Li depletion and structural degradation at the NCM523/Li6PS5Cl interface during charging. The results reveal a Li‐depleted amorphous interphase that impedes Li transport, while LiNbOy coating suppresses interfacial degradation and preserves the solid‐electrolyte structure ...

A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.

A self‐adaptive gradient SCMN buffer layer is designed based on a conduction‐nucleation competition mechanism. The design dynamically optimizes ion/electron conduction and lithiophilicity, guiding dendrite‐free lithium deposition. Consequently, symmetric cells deliver exceeding 1600h at 1.5 mA cm−2, and the LiCoO2‐based full cells exhibit 98.5 ...

Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

Fast charging drives graphite anodes far from equilibrium, yet where lithium plating begins has remained hidden. Operando optical microscopy here reveals that neighboring regions advance through the staging sequence asynchronously, and that domains reaching advanced lithiation earliest become the preferential sites where plating initiates.

Three phenothiazine‐based polyamides featuring gradually strengthened electron‐withdrawing linkers are developed as high‐voltage cathodes for lithium‐organic batteries. The linker motif serves not only as a structural bridge to suppress solubility, but also as a functional design element that governs optoelectronic properties and electron/ion transport
