This work deciphers the modulation essence of p bands on Li-S chemistry by systematically studying the kinetic behaviors of Li-S chemistry on Co-based compounds with fixed metal cation and varied non-metal anions. The p bands originated from the non-metal anions can benefit the interfacial charge interaction by tuning the electron energy of the valence band, endowing S@rGO/CoP with unprecedented rate performance for Li-S batteries. It offers a new vision to rationally design highly efficient materials for Li-S batteries.

Nanoporous thermochromic VO(2) films with low optical constants and tunable thicknesses have been prepared by polymer-assisted deposition. The film porosity and thickness change the interference relationship of light reflected from the film-substrate and the air-film interfaces, strongly influencing the optical properties of these VO(2) films. Our optimized single-layered VO(2) films exhibit high integrated luminous transmittance (T(lum,l) = 43.3%, T(lum,h) = 39.9%) and solar modulation (ΔT(sol) = 14.1%, from T(sol,l) = 42.9% to T(sol,h) = 28.8%), which are comparable to those of five-layered TiO(2)/VO(2)/TiO(2)/VO(2)/TiO(2) films (T(lum,l) = 45%, T(lum,h) = 42% and ΔT(sol) = 12%, from T(sol,l) = 52% to T(sol,h) = 40%, from Phys. Status Solidi A2009, 206, 2155-2160.). Optical calculations suggest that the performance could be further improved by increasing the porosity.
