Abstract Exceptionally large surface area and well-defined nanostructure are both critical in the field of nanoporous carbons for challenging energy environmental issues. The pursuit ultrahigh while maintaining definite remains a formidable challenge because extensive creation pores will undoubtedly give rise to damage nanostructures, especially below 100 nm. Here we report that high up 3,022 m 2 g −1 can be achieved hollow carbon nanospheres with an outer diameter 69 nm by simple...
A Co(OH)2/zeolite nanocomposite with an extraordinarily high specific capacitance is described. Nanometer-sized Co(OH)2 whiskers on the zeolite surface permit electrochemical accessibility and a fast diffusion rate of electrolyte through material, resulting in approaching theoretical limit. Increasing loading increases whisker growth (see Figure), until bulk begins to nucleate grow solution (arrows).
Ordered π-columns and open nanochannels found in covalent organic frameworks (COFs) could render them able to store electric energy. However, the synthetic difficulty achieving redox-active skeletons has thus far restricted their potential for energy storage. A general strategy is presented converting a conventional COF into an outstanding platform storage through post-synthetic functionalization with radicals. The radical openly accessible polyradicals immobilized on pore walls undergo...
Organic batteries free of toxic metal species could lead to a new generation consumer energy storage devices that are safe and environmentally benign. However, the conventional organic electrodes remain problematic because their structural instability, slow ion-diffusion dynamics, poor electrical conductivity.

A brand new polysulfide entrapping strategy based on the ferroelectric effect has been demonstrated for first time. By simply adding nano-ferroelectrics (BaTiO3 nanoparticles) into cathode, heteropolar polysulfides can be anchored within cathode due to internal electric field originated from spontaneous polarization BaTiO3 nanoparticles, and thus significantly improving cycle stability of Li–S batteries. As a service our authors readers, this journal provides supporting information supplied...
