“…Veeraraghavan et al [44] reported 35 cycles at C/15 and 15.8% discharge capacity loss for the Sn coated graphite materials. Carbon-tin composites produced by ball milling showed a capacity drop from 1070 to 380 mAhg -1 over 20 cycles [45]. Tingraphite materials prepared by chemical reduction of SnCl 4 showed the initial reversible massic capacity of 630 mAhg −1 , which decayed to 415 mAhg −1 after 25 cycles [46].…”

“…Sn, SnO 2 and Sn-based alloy composites with graphite [44,45,46,47], amorphous carbon [48,49] or carbon nanotubes [50] used as a mechanical support and conductive matrix for tin-based active material particles also offer a unique opportunity to combine the stable cyclability of the carbon with the high storage capacity of tin-based materials.…”

“…Fabrication techniques of nano-structured Sn, SnO 2 and carbon/tin composites include autocatalytic deposition [44], ball-milling [41,45,51], chemical reduction [46,50], electrodeposition [47], hydrolysis [48], pyrolysis [49,] sputtering [52], plasma laser deposition (PLD) [53], sol-gel techniques [54], partial reduction [55], precipitation [56], sonochemical methods [57], and vapor deposition [58]. However, these processes often involve several time consuming steps and offer only limited control of the particle size and distribution.…”

In this paper we report results of a novel synthesis method of thin-film composite Sn/C anodes for lithium batteries. Thin layers of graphitic carbon decorated with uniformly distributed Sn nanoparticles were synthesized from a solid organic precursor Sn(IV) tert-butoxide by a one step microwave plasma chemical vapor deposition (MPCVD). The thin-film Sn/C electrodes were electrochemically tested in lithium half cells and produced a reversible capacity of 440 and 297 mAhg -1 at C/25 and 5C discharge rates, respectively. A long term cycling of the Sn/C nanocomposite anodes showed 40% capacity loss after 500 cycles at 1C rate.

“…The nanocrystalline Si content in the composite is 20 wt %. We chose this percentage based on the results of a previous investigation on ballmilled Sn-graphite 20 and ballmilled Si-graphite. 21 The mixtures were ballmilled for 5, 10, and 20 h, respectively, to obtain three batches of Si-MCMB composites.…”

“…Over the last years several studies about lithium storage in carbon materials derived from rice husk, sugar walnut and almond, coffee, peanut shells, lignin, cotton, wool, starch and oak have been reported. [21][22][23][24][25][26][27][28][29][30] Results from these works have shown that the electrochemical behavior of the obtained carbonaceous material depends strongly on the type of biomass and on the carbonization conditions. The reversible specific capacity, columbic efficiency, potential profile and fading capacity will depend on the structure, morphology, and chemical composition of the carbon present in the material.…”

Materiais carbonaceos com diferentes estruturas são preparados da carbonização do bagaço da cana de açúcar. Os materiais obtidos são caracterizados utilizando-se microscopia de varredura eletrônica e técnicas eletroquímicas. Dependendo das condições de carbonização é possível obter fuligens ricas de partículas tipo flocos ou tipo colméia de abelha, cuja concentração tem grande influência sobre a armazenagem de lítio nos eletrodos. Para fuligens ricas de partículas do tipo colméia observa-se uma capacidade específica reversível da ordem de 310 mAh g -1. Os resultados sugerem que o bagaço da cana pode ser um percursor com potencial para o desenvolvimento de materiais anódicos para baterias de ions de lítio.Carbonaceous materials with different structures are prepared by carbonization of sugarcane bagasse. Depending on carbonization conditions, it is possible to obtain soot rich in flakes or in honeycomb-shaped micrometric particles, whose concentration has large influence on lithium storage into electrodes. The soot rich in honeycomb-shaped particles provides the best electrochemical performance, with a reversible specific capacity of 310 mAh g -1 . The results suggest that the sugarcane bagasse can be potentially used in the design of anodic materials for lithium ion batteries. Keywords: sugarcane, honeycomb carbon, lithium ion battery IntroductionLi-ion battery is an electrochemical cell with electrodes that can be prepared with several Li intercalation compounds. The electrochemical performance of electrodes consisting of these compounds is strongly controlled by the structural and electronic properties of the intercalation material.1,2 Over the last years several oxides, alloys, and carbons have been claimed for the preparation of Li-ion battery. LiCoO 2 and graphite with spheroid shape are the most commonly employed cathodic and anodic materials in commercial Li-ion batteries, respectively. This is because these two compounds, which respectively provide a practical specific reversible capacity of approximately 135 and 360 mAh g -1 , allow the preparation of electrodes with good mechanical properties, low electrochemical impedance, low ohmic drop and relative good thermal stability. They also withstand the pressure applied inside the cells during the preparation of the electrodes and resist the mechanical stress associated with the Li intercalation that takes place during volume changes and double-layer formation throughout electrical polarization.3 However, in the case of graphite, the control of structural properties in large-scale processing plants is not easy, specially when this 'plant' is natural. The genesis of graphite mine can undergo alterations during its extraction. For example, the dimension of crystallites is a parameter that has implications in the preparation of electrode and in the kinetics of lithium intercalation, as well as in the value of specific capacity Here we present an investigation of Li electrointercalation in carbonaceous materials prepared from abundant, inexpensive biomass (less...
