Abstract Cobalt‐free LiNiO 2 is an attractive cathode material with high energy density and low cost but suffers from severe structural degradation poor performance. Here, a molten salt‐assisted synthesis combined Li‐refeeding strategy proposed to obtain nonstoichiometric Li 1+ x Ni 1‐ O submicron particle size superior rate The slightly Li‐rich single‐crystalline characters inhibit + /Ni 2+ anti‐site defects mitigates the undesirable phase evolution. Remarkably, 1.045 0.955 exhibits...

Abstract The wollastonite was grafted with different silane coupling agents, which could improve interface adhesion. Wollastonite and modified wollastonite‐reinforced poly(ether ether ketone) (PEEK) composites were prepared by melt blending. mechanical properties, rheology behavior, thermal properties of the investigated. PEEK exhibited better than unmodified based on good interfacial had lower activation volume complex shear viscosity. Furthermore, higher crystallization peak temperature (...

Nanocomposites of Sulfonated Poly(Aryl ether ketone) (SPAEK) and functional multiwall carbon nanotubes (a-MWNTs) were fabricated by a solution method. The results showed that the composites exhibited higher dielectric constant was near 600 when volume fraction carbon-nanotubes 0.07 (7 vol%) at 103 Hz. percolation threshold a-MWNTs/SPAEK only 3 vol% a-MWNTs, could reach 210. changed little with frequency increase content more than vol%, keep high high-frequency (>200, 106 Hz).

Chemical functionalized graphene (f-G) was obtained by the reaction of residual epoxide and carboxyl functional groups on hydrazine-reduced (G) sheets with hydroquinone. The efficacy functionalization confirmed X-ray photoelectron spectroscopy thermogravimetric analysis. Atomic force microscopy transmission electron images showed that can be easily exfoliated into nanosheets composed single or bilayers sheets. f-G used to prepare conductive poly (ether sulfone) (PES) composites (f-G/PES) via...

Abstract Magnetite (Fe 3 O 4 ) has a large theoretical reversible capacity and rich Earth abundance, making it promising anode material for LIBs. However, suffers from drastic volume changes during the lithiation process, which lead to poor cycle stability low‐rate performance. Hence, there is an urgent need solution address issue of expansion. Taking inspiration how glycophyte cells mitigate excessive water uptake/loss through their cell wall preserve structural integrity cells, we designed...
