Developing stable conductive materials with high conductivity for sodium ion (Na+) batteries attracts ever-increasing attention. In this work, MOF-based solid Na+-conducting composites functionalized by ionic liquids (ILs) were explored through introducing five kinds of ILs and their corresponding sodium salts into the pores of MIL-101-SO3Na. The p...

The combination of ionic liquids (ILs) and metal organic frameworks (MOF) as a new type of hybrid ionic conductor has raised extensive concern. Novel solid electrolytes with high ionic conductivities and good cycle performance have been successfully synthesized by loading ILs into nanoarchitectures of MOF materials. In this work, two highly conduct...

The enriched lithium ion containing layered oxide cathode materials Li(Li0.05Ni0.7 - x Mn0.25Co (x) )O-2 have been prepared by using facile sol-gel technique. The phase purity and crystalline nature of the layered oxide cathodes have determined by X-ray diffraction analysis. Surface morphology and elemental analysis have been carried out using scan...
A poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) coated Li4Ti5O12 (LTO/PP) composite is synthesized by a facile and convenient approach, which involves dispersing LTO in an aqueous solution of PEDOT: PSS, followed by rotary evaporation accompanied by an ultrasonic procedure. After the coating process, LTO is covered by a homog...
A large amount of fine carbon powders (graphite and cokes) are generated as the solid waste in the manufacture of carbon-based materials in industry. How to utilize these abundant powders to generate products with high value still remains a big challenge. Herein, we report the preparation of porous carbon microspheres (PCMs) employing waste non-gr...
To solve the recycling challenge for aqueous binder based lithium-ion batteries (LIBs), a novel process for recycling and resynthesizing LiNi1/3Co1/3Mn1/3O2 from the cathode scraps generated during manufacturing process is proposed in this study. Trifluoroacetic acid (TFA) is employed to separate the cathode material from the aluminum foil. The eff...
We report the facile preparation of graphitized porous carbon microspheres (GPCMs) by the spray drying technique using carbon black (CB) nanoparticles as the primary carbon resource and sucrose as the binder, followed by graphitization at 2800 degrees C. The samples were characterized by X-ray diffraction, transmission electron microscopy, scanning...
A novel Si/porous-C composite with buffering voids was prepared by the co-assembly of phenolformaldehyde resin, SiO2 and Si nanoparticles, followed by a carbonizing process and subsequent removal of SiO2 template. Si nanoparticle was coated with a layer of porous carbon shell with rationally designed void in between which provides the accommodating...
