“…This nanohybrid shows a specific capacity in excess of 900 mA h g À1 after 50 discharge-charge cycles and a high Coulombic efficiency of 99.7 % at a rate of 1 C. Although plum-pudding nanohybrids have been found to be an effective structure for improving the electrochemical properties of the M IVA elements, their fabrication is not easy. In this context, many oxides, sulfides, or oxysulfides, including SiO x , [63][64][65][66] SnO 2 , [30,31,34,35,67,68] SnS, [69][70][71] SnS 2 , [72][73][74][75] and SnS 2 /SnO 2 , [76] have been studied as high-capacity anodes with improved cycling performance compared with their pristine elements. During the initial lithium-uptake process, the M IVA X a Y b compound can lithiate electrochemically, thus leading to the in situ formation of inactive components, which can also serve as the expected matrices to buffer the volume variation upon subsequent cycles.…”

Lithium-ion batteries (LIBs) represent the state-of-the-art technology in rechargeable energy-storage devices and they currently occupy the prime position in the marketplace for powering an increasingly diverse range of applications. However, the fast development of these applications has led to increasing demands being placed on advanced LIBs in terms of higher energy/power densities and longer life cycles. For LIBs to meet these requirements, researchers have focused on active electrode materials, owing to their crucial roles in the electrochemical performance of batteries. For anode materials, compounds based on Group IVA (Si, Ge, and Sn) elements represent one of the directions in the development of high-capacity anodes. Although these compounds have many significant advantages when used as anode materials for LIBs, there are still some critical problems to be solved before they can meet the high requirements for practical applications. In this Focus Review, we summarize a series of rational designs for Group IVA-based anode materials, in terms of their chemical compositions and structures, that could address these problems, that is, huge volume variations during cycling, unstable surfaces/interfaces, and invalidation of transport pathways for electrons upon cycling. These designs should at least include one of the following structural benefits: 1) Contain a sufficient number of voids to accommodate the volume variations during cycling; 2) adopt a "plum-pudding"-like structure to limit the volume variations during cycling; 3) facilitate an efficient and permanent transport pathway for electrons and lithium ions; or 4) show stable surfaces/interfaces to stabilize the in situ formed SEI layers.

“…SnS as anode materials for lithium ion batteries has high theoretical specific capacity, and low lost and suitable working potential. To solve the problem of capacity fading for SnS electrode caused by large volume changes during cycles, one effective way is preparation of the SnS/C composite to enhance the cycling stability [11][12][13]. SnS/C composite can combine the advantages of carbon (good cycling stability and long life) and SnS (high specific capacity) because carbon as a buffer can alleviate the volume stress and maintain the structural integrity of electrode materials during the discharge-charge process.…”

N-doped graphene/SnS composite as highperformance anode materials has been synthesized by a simultaneous solvothermal method using ethylene glycol as solvent. The morphology, structure, and electrochemical performance of N-doped graphene/SnS composite were investigated by transmission electron microscope (TEM), X-ray diffraction (XRD), Raman spectra, Fourier transform infrared (FTIR) spectra, X-ray photoelectron spectroscopy (XPS), and electrochemical measurements. The SnS nanoparticles with sizes of 3-5 nm uniformly distribute on the N-doped graphene matrix. The N-doped graphene/SnS composite exhibits a relatively high reversible capacity and good cycling stability as anode materials for lithium ion batteries. The good electrochemical performance can be due to that the N-doped graphene as electron conductor improves the electronic conductivity of composite and elastic matrix accommodates the large volume changes of SnS during the cycles.

“…Currently, tremendous efforts have been devoted to combining the unique properties of individual constituents to further address this problem, e.g. the combination of Cu-Sn-S film, 10 the introduction of carbon-coating into SnS, 11 and the integration of Sn-Zn-Cu multilayer film, 12 all of which improve the conductivity and capacity of sulfides. As a result, it would be fantastic to utilize various elements as a quaternary compound for lithium storage -Cu 2 ZnSnS 4 (CZTS), and the film fabricated by magnetron sputtering is uniform with a determinate constitution.…”

Cu2ZnSnS4 (CZTS) is an important material in low-cost thin film solar cells and is also a promising candidate for lithium storage. In this work, a novel three-dimensional CZTS film coated with a lithium phosphorus oxynitride (LiPON) film is fabricated for the first time and is applied to thin-film lithium-ion batteries. The modified film exhibits an excellent performance of ∼900 mAh g(-1) (450 μAh cm(-2) μm(-1)), even after 75 cycles. Morphology integrity is still maintained after repeated lithiation/delithiation, and the main reaction mechanism is analyzed in detail. The significant findings from this study indicate the striking advantages of modifying both the surface and structure of alloy-based electrodes for energy storage.
