Nanosulfur/polyaniline/graphene composites for high-performance lithium–sulfur batteries: One pot in-situ synthesis

Microporous carbon nanosheets derived from corncobs for lithium–sulfur batteries

“…Therefore, various attempts to overcome the above-mentioned problems appeared, which focus on enhancing the electrical conductivity of the cathode and trapping the polysulfides in a conducting matrix during cycling. Various materials are paid much attention to improve the discharge capacity and the cycle life of Li-S batteries, such as porous carbon [5,6], polypyrrole [7,8], polyaniline [9,10], graphene [11][12][13], and grapheme oxide [14], hollow carbon nanofibers [15,16]. In particular, using porous carbon materials to immobilize sulfur have been proved to be effective in improving the sulfur utilization and reduce the shuttling of polysulfides due to their excellent electric conductivity, large surface area and pore volume and strong adsorption ability.…”

A Simple Preparation of Polyaniline-coated Sulfur Composites for use as Cathodes in Li–S Batteries

“…Graphene, [3][4][5][6] carbon nanotubes (CNTs), [7][8][9] and carbon [10][11][12] have been investigated as sulfurbased cathode materials. Carbon-conductive polymer composite materials [13][14][15][16][17][18][19] and conductive polymer matrices [20][21][22][23][24][25][26][27][28][29] have also been widely tested for their ability to improve battery performance. Huang et al showed that graphene-coated sulfur composites could be used to improve cycling performance.…”

“…18 Liu et al synthesized nanosulfur/polyaniline/graphene composites via one-pot in-situ synthesis, and they showed an energy capacity of 600 mAh g ¹1 at 100 cycles with a 0.1 C-rate. 19 Graphene is a very good material for improving the electric conductivity of a material, but in terms of price and processibility, PANi itself is a common and good material for improving the performance by preventing polysulfide dissolution. Xiao et al reported improved cycling performance using sulfurcoated nanotube-type polyaniline.…”

Graphene-wrapped sulfur nanospheres with ultra-high sulfur loading for high energy density lithium–sulfur batteries

“…Many pioneering work have reported that the use of conductive carbon matrix such as active carbon [19,20], mesoporous carbon [21], carbon nanotubes [22] and graphene [23,24], and conducting polymers including polypyrrole [25,26] and PANI [27][28][29] is one of the most promising strategies to resolve these problems.…”
