Highly conductive copolymer/sulfur composites with covalently grafted polyaniline for stable and durable lithium-sulfur batteries

A review on electronically conducting polymers for lithium-sulfur battery and lithium-selenium battery: Progress and prospects

“…A copolymer can be synthesized based on one kind of polymer with another polymer by grafting method, and the physical and chemical properties of the polymer could be thoroughly modified [29]. Dai et al [30] synthesized conducting PANI containing sulfur-rich copolymer/sulfur composite i.e. cp (S-g-PANI)/S (abbreviated as SPAS) by a two-step method.…”

“…They prepared the honeycomb polyaniline-dodecyl benzene sulfonic acid (hPANI-DBSA) film through the breath figure (BF) method (Fig. 4e) and then the sulfur was electrodeposited on the honeycomb membrane [25] Copyright 2015, Royal Society of Chemistry; (b) Synthesis of the hPANIs@S composite [26] Copyright 2016, Elsevier BV; (c) Synthesis of SAS and SPAS [30] Copyright 2019, Elsevier Ltd; (d) Schematic illustrating the stabilization and enrichment of quinonoid imines by PA, as well as the reversible transition between protonated and deprotonated states with simultaneous polysulfide desorption and adsorption [31] Copyright 2017, Wiley-Blackwell; (e) Schematic representation of preparing the honeycomb structure [32] Copyright 2018, Taiwan Institute of Chemical Engineers; (f) SEM and TEM images of the as-prepared HCPSs [33] Copyright 2015, Elsevier BV. surface (hPANI-DBSA/S).…”

Intrinsically conducting polymers and their combinations with redox-active molecules for rechargeable battery electrodes: an update

“…A copolymer of PANI and a sulfur-containing substituted aniline has been examined as positive electrode in search for a stable lithium-sulfur battery (Dai et al 2019). After 500 cycles 70.5% capacity retention were recorded.…”

History and recent developments in divergent electrolytes towards high-efficiency lithium–sulfur batteries – a review

“…Various suggestions have been proposed to solve these problems. Most studies have been focused on nanostructured host materials such as porous carbons (nanotubes, nanofibres, and spheres), [4][5][6][7][8][9] graphene, [10][11][12][13] graphene oxide, [14][15][16] conductive polymers [17][18][19][20][21] and inorganic nanomaterials. [22][23][24] The conducting porous cathode hosts could enhance the electronic conductivity and confine polysulfides within their framework, subsequently improving the discharge capacity.…”
