Published: Feb. 17, 2025

Abstract The morphological distribution of absorbent in composites is equally important with absorbents for the overall electromagnetic properties, but it often ignored. Herein, a comprehensive consideration including component regulation, layered arrangement structure, and gradient concentration was used to optimize impedance matching enhance loss. On microscale, incorporation magnetic Ni nanoparticles into MXene nanosheets (Ni@MXene) endows suitable intrinsic permittivity permeability. macroscale, Ni@MXene increases effective interaction area waves, inducing multiple reflection/scattering effects. this basis, according analysis absorption, reflection, transmission (A–R–T) power coefficients composites, constructed realize at low-concentration surface layer, loss middle interlayer microwave reflection high-concentration bottom layer. Consequently, composite (LG5-10–15) achieves complete absorption coverage X-band thickness 2.00–2.20 mm RL min −68.67 dB 9.85 GHz 2.05 mm, which 199.0%, 12.6%, 50.6% higher than non-layered, descending respectively. Therefore, work confirms importance structure improving performance broadens design high-performance materials.

Abstract Practical application of Li metal anodes (LMAs) is restricted by growth dendrites. Achieving uniform deposition with high practically available specific capacity vital to obtain advanced LMAs. Herein, an ultralight V 2 CT x /bacterial cellulose (U‐V /BC) foam a volume density 0.039 g cm −3 guided tertiary butanol avoid restacking both and BC. The lithiophilic functional groups BC synergistically induce the nucleation. loose stacking structure U‐V /BC provides 3D ion channels for accelerating + diffusion, homogeneous flux, as well enough sites interspace deposition. As result, /BC@Li exhibits superior stability 2800 h at 5 mAh −2 mA ultrahigh 2040 −1 . Furthermore, full‐cells paired LiFePO 4 cathodes possess remarkable retention 80.7% after 800 cycles 1 C.
