The emergence of flexible and wearable electronic devices with shape amenability high mobility has stimulated the development power sources to bring revolutionary changes daily lives. conventional rechargeable batteries fixed geometries sizes have limited their functionalities in applications. first‐ever graphene‐based fibrous are reported this work. Ultralight composite fibers consisting reduced graphene oxide/carbon nanotube filled a large amount sulfur (rGO/CNT/S) prepared by facile,...
Abstract SnS 2 nanoplatelet electrodes can offer an exceptionally high pseudocapacitance in organic Na + ion electrolyte system, but their underlying mechanisms are still largely unexplored, hindering the practical applications of pseudocapacitive anodes Na‐ion batteries (SIBs) and hybrid capacitors (SHCs). Herein, nanoplatelets grown directly on SnO /C composites to synthesize /graphene‐carbon nanotube aerogel (SnS /GCA) by pressurized sulfidation where original morphology carbon framework...
Although lithium sulfur batteries (LSBs) have attracted much interest owing to their high energy densities, synthesis of high‐rate cathodes and understanding volume expansion behavior still remain challenging. Herein, electrospinning is used prepare porous carbon nanofiber (PCNF) hosts, where both the pore surface area are tailored by optimizing sacrificial agent content activation temperature. Benefiting from ameliorating functional features electrical conductivity, large volume, Li ion...
Three-dimensional graphene aerogel/TiO2/sulfur (GA/TiO2/S) composites are synthesized through a facile, one-pot hydrothermal route as the cathode for lithium-sulfur batteries. With high sulfur content of 75.1 wt %, conductive, highly porous composite electrode delivers discharge capacity 512 mA h/g after 250 cycles at current rate 1 C with low decay 0.128% per cycle. The excellent capacities and cyclic stability arise from several unique functional features cathode. (i) conductive aerogel...
Abstract This paper reports the rational assembly of novel hollow porous carbon nanospheres (HPCNSs) as hosts phosphorous (P) active materials for high‐performance sodium‐ion batteries (SIBs).
