USTC & SES AI developed an MTP electrolyte with "Planar Aligned Electron Channels." This enables 4C ultrafast charging (<15 min) in 400 Wh/kg practical Li-metal pouch cells by accelerating interfacial electron transfer.

Inspired by maglev, Fuzhou Univ. researchers developed a "Mechanical Balance" strategy. By using anion clusters to offset polymer-Li+ attraction and aligned channels, they achieved 1.2 mS/cm conductivity and 3500 stable cycles in solid electrolytes.

Prof. Cheol-Min Park's team identifies LiGa as a stable, conductive anode for solid-state batteries. It suppresses dendrites via interstitial Li storage, outperforming Li-metal in stability and rate capability.

Prof. Yi Cui's team utilized urea as a hydrotrope to boost FeSO₄ solubility to 10 M. This suppresses HER, raising Iron anode CE to 96.5% with 300h stability and cutting electrolyte costs by 90%, paving the way for grid-scale iron batteries.

Crystal structure differences and their decisive impact on full-cell performance

This review covers how synchrotron X-ray and neutron techniques "open the black box" of solid-state batteries. These in-situ tools reveal the true mechanisms of interface failure and dendrite growth, enabling a shift from guesswork to rational design.

A new "solid dissociation" paradigm, using vdW crystals as "solid solvents" to dissolve salts, unlocks a vast library of 70+ new superionic conductors, enabling true "electrolyte engineering" for solid-state batteries.

Why do lean electrolyte LMBs fail fast? This study reveals the cause isn't bulk "dry-out," but "local dry-out" and clogging within porous lithium, which deactivates the anode.

By designing an "anion-rich" solvation structure, a new polymer electrolyte solves key stability issues in solid-state batteries, enabling a record-breaking and safe >600 Wh/kg pouch cell.

By pairing a porous scaffold with an ultra-thin separator, this work boosts anode-free battery cycle life and energy density (>10%) by proving it suppresses "dead" lithium formation.

A 2D polyamide interface layer enables record-breaking anode-free batteries by guiding uniform Li plating.

This study finds atomic disorder, not initial conductivity, is key for fast-charging anodes. A disordered insulator outperformed an ordered metal by suppressing Li-ion ordering, a new design strategy.

A review of the challenges & future of high-temp lithium metal batteries (HT-LMBs) for extreme applications.

This research breaks the design bottleneck between performance and recyclability with a self-assembling solid-state electrolyte. Inspired by Kevlar, it combines high structural stability with excellent ionic conductivity. Post-use, the material rapidly dissolves in a solvent, enabling the non-destructive recovery of core battery components—a key breakthrough for sustainable, high-performance batteries.
