The huge volume expansion in Sn-based alloy anode materials (up to 360%) leads to a dramatic mechanical stress and breaking of particles, resulting in the loss of conductivity and thereby capacity fading. To overcome this issue, SnO2@C nano-rattle composites based on <10 nm SnO2 nanoparticles in and on porous amorphous carbon spheres were synthesized using a silica template and tin melting diffusion method. Such SnO2@C nano-rattle composite electrodes provided two electrochemical processes: a partially reversible process of the SnO2 reduction to metallic Sn at 0.8 V vs. Li+/Li and a reversible process of alloying/dealloying of LixSny at 0.5 V vs. Li+/Li. Good performance could be achieved by controlling the particle sizes of SnO2 and carbon, the pore size of carbon, and the distribution of SnO2 nanoparticles on the carbon shells. Finally, the areal capacity of SnO2@C prepared by the melt diffusion process was increased due to the higher loading of SnO2 nanoparticles into the hollow carbon spheres, as compared with Sn impregnation by a reducing agent.

“…The enlarged TEM image and the FFT pattern in Fig. 2c [32], the lattice fringe with an interplanar spacing of $0.320 nm was ascribed to the (0 0 2) crystallo-graphic planes of graphitic carbon [27,28] and the fringe spacing of 0.261 nm attributed to the (1 0 1) planes of SnO 2 nanocrystallites [16], which was the strong supporting evidence of the formation of CQDs/SnO 2 -Co 3 O 4 composite. The energy-dispersive X-ray spectrum (EDS) analysis (Fig.…”

“…But the limited current density, small surface area and low efficient electron-mass transfer hinder its practical application [11][12][13]. Tin oxide (SnO 2 ) is identified as a good conductor of electricity used in electrochemistry and has received considerable attention over the past few decades [14][15][16]. The composites based on metal oxide and SnO 2 can efficiently improve the electronic conductivity property [17].…”

“…Such a high lithium storage capacity has a signi¯cantly higher value than the theoretical capacity of SnO 2 , and it might be attributed to the high surface area and short di®usion pathlength due to the highly ordered mesoporous structure. [32][33][34] The meso-ATO-10 delivers an initial discharge capacity of 1940 mAhg À1 and charge capacity of 1049 mAhg À1 , which is quantitatively similar to meso-ATO-0. For the meso-ATO-10 material, the dissociation of the oxide takes place at higher potential and the peak is broader than that of the meso-ATO-0 material.…”

Highly ordered mesoporous antimony-doped tin oxide (ATO) materials, containing di®erent amount of antimony in the range of 0-50 mol%, are prepared via a nanoreplication method using a mesoporous silica template. The mesoporous ATO materials thus obtained exhibit high electrical conductivity, high reversible capacity, superior cycle stability and good rate capability as anode materials for lithium-ion batteries, compared to those of pure mesoporous tin oxide. Amongst the ATO materials in this work, the mesoporous ATO material with 10 mol% of antimony has highest discharge capacity of 1940 mAhg À1 (charge capacity of 1049) at the 1st cycle, best cycle performance (716 mAhg À1 at 100th cycle) and excellent rate capability, which are probably due to the enhanced electrical conductivity as well as reduced crystalline size.
