Abstract Magnesium rechargeable batteries potentially offer high-energy density, safety, and low cost due to the ability employ divalent, dendrite-free, earth-abundant magnesium metal anode. Despite recent progress, further development remains stagnated mainly sluggish scission of magnesium-chloride bond slow diffusion divalent cations in cathodes. Here we report a battery chemistry that utilizes monochloride expanded titanium disulfide. Combined theoretical modeling, spectroscopic analysis,...
Abstract Multivalent‐ion batteries are emerging as low‐cost, high energy density, and safe alternatives to Li‐ion but challenged by slow cation diffusion in electrode materials due the polarization strength of Mg‐ Al‐ions. In contrast, Ca‐ion has a low similar that Li‐ion, therefore battery will share advantages while avoiding kinetics issues related multivalent batteries. However, there is no known utilizes chemistry limited success storage materials. Here, low‐cost aqueous based on highly...
The universal application of wearable strain sensors in various situations for human-activity monitoring is considerably limited by the contradiction between high sensitivity and broad working range. There still remains a huge challenge to design featuring simultaneous range sensitivity. Herein, typical bilayer-conductive structure Ti3C2Tx MXene/carbon nanotubes (CNTs)/thermoplastic polyurethane (TPU) composite film was developed simple scalable vacuum filtration process utilizing porous...
All-solid-state sodium batteries (ASSSBs) with nonflammable electrolytes and ubiquitous resource are a promising solution to the safety cost concerns for lithium-ion batteries. However, intrinsic mismatch between low anodic decomposition potential of superionic sulfide high operating potentials sodium-ion cathodes leads volatile cathode-electrolyte interface undesirable cell performance. Here we report high-capacity organic cathode, Na4 C6 O6 , that is chemically electrochemically compatible...
All-solid-state sodium batteries (ASSSBs) are promising candidates for grid-scale energy storage. However, there no commercialized ASSSBs yet, in part due to the lack of a low-cost, simple-to-fabricate solid electrolyte (SE) with electrochemical stability towards Na metal. In this work, we report family oxysulfide glass SEs (Na
Poly(ethylene oxide) (PEO)-based solid polymer electrolytes (SPEs) with nonflammability, shape flexibility, and high SPE/Li interfacial stability are poised to be an enabler for solid-state lithium batteries, but their application is restricted by low room-temperature ionic conductivity poor mechanical strength at elevated temperatures. Herein, hyperstar polymers synthesized hyperbranched PEO serving as the star core linear polystyrene (PS) arms. The topological structure suppresses...

Well-defined polyacrylonitriles (PANs) with different molecular weights were synthesized through an activator regenerated by electron-transfer atom-transfer radical polymerization method and employed as binders in silicon negative electrode for lithium-ion batteries. Compared poly(vinylidene fluoride) carboxyl methyl cellulose binders, the performance of PANs is well-improved. Specifically, at 100 mA g–1 from 0.01 to 1.5 V, initial discharge capacity PAN100-based 4147.8 h still remains about...
Sulfide-based Na-ion conductors are promising electrolytes for all-solid-state sodium batteries (ASSSBs) because of high ionic conductivity and favorable formability. However, no effective strategy has been reported long-duration Na cycling with sulfide-based interfacial challenges. Here we demonstrate that a cellulose–poly(ethylene oxide) (CPEO) interlayer can stabilize the interface between sulfide electrolyte (Na3SbS4) by shutting off electron pathway decomposition reaction. As result,...
