“…Thermal expansion (TE) features of materials such as negative TE (contraction on heating), NTE, TE hysteresis, HTE, and close-to-zero TE, ZTE, have enormous industrial merit and been widely utilized in the preparation of composite materials, optical fibers and energy storage systems [1][2][3][4][5][6][7]. NTE results from the coupling between the resonances of planar material elements and phononvibrational modes [8], the coupling between acoustic and soft transverse optical phonons [9] and so on.…”

The sulfur content present in graphene oxide prepared by Hummers' method has only been addressed by few papers so far. By modified Hammers method we synthesized thermally stable in ambient environment multilayer sulphur-doped graphene oxide. The samples were heat treated in an electrical furnace setup at different ambient temperatures and their crystallite size and linear coefficient of thermal expansion were extracted from Raman band intensity peak ratio as a function of temperature. We found unusually large (in comparison with graphene oxide) contraction on heating of multilayer two weight percent sulphur-doped graphene oxide with carbon to oxygen ratio of 2.3 in a narrow temperature range (308-318 K) with the lowest value of the linear thermal expansion coefficient of -18 ppm 1/K. Based upon an examination of the synthesized sulphur-doped graphene diffractograms, it is suggested that negative thermal expansion stems from the phonon backscattering by the sulphur impurity sites and the edges of the layers. The obtained experimental results have potential practical applications for fabrication of solar cells, sensors, lubricators, thermal actuators and also wavelike (second sound) thermal transport structures.

More measures are being developed to enhance the electrochemical stability of single‐crystal LiNi0.6Co0.2Mn0.2O2 (NCM622), but few focus on improving the stability of NCM622 through heat and deformation management. Herein, a negative‐thermal‐expansion (NTE) material of zirconium tungstate ZrW2O8 is adopted to modify NCM622 via a facile method, and the sample with a proper content of ZrW2O8 exhibits superior cycle performance and rate capability. The capacity retention ratio of modified NCM622 is 86.2% (from 193.6 to 166.8 mAh g−1) after 100 cycles at 2 C between 2.8 and 4.5 V at 60 °C, whereas that of the pristine NCM622 is only 77.5% (from 183.8 to 142.4 mAh g−1). According to various analysis results, the possible enhancing mechanisms of ZrW2O8 for NCM622 are discussed. It is an alternative for the remaining good structure of energy materials using NTE materials.
