Embedding ZnSe nanodots in nitrogen-doped hollow carbon architectures for superior lithium storage

Construction of ultrafine ZnSe nanoparticles on/in amorphous carbon hollow nanospheres with high-power-density sodium storage

“…For example, Wu and co-workers reported that ZnSe composite with hollow carbon could deliver a high reversible discharge capacity M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 4 of 1134 mAh g -1 after cycled for 500 cycles at 0.6 A g -1 . [33] Qian et al explained the reason for the extra rising capacity by the generation and the activation of Se during the electrochemical process. [34] More recently, Mai and his group used ZnSe microspheres (ZnSe MSs)-CNT composite as an anode for SIBs, and the results indicated the possibility of delivering capacity of 387 mAh g -1 for 180 cycles.…”

Sandwich Structures Constructed by ZnSe⊂N‐C@MoSe2 Located in Graphene for Efficient Sodium Storage

“…Taking ZnSe as an representative, the most pervasive strategies to settle the above shortcomings are to construct porous nanostructure and hybridize with various carbon or other stable performance materials. [16][17][18][19][20] For instance, Xi et al have prepared a hierarchical hybrid material of ultrafine ZnSe particles growing on/in amorphous hollow carbon nanospheres, which provides a high capacity of 361.9 mAh g −1 at 1.0 A g −1 after 1000 cycles for SIBs. [21] Kong et al have reported ZnSe/CoSe encapsulated in N-doped carbon polyhedra by solution method…”

Nanostructured metal chalcogenides confined in hollow structures for promoting energy storage

“…However, with the increasing demand for energy density and cycle life, the theoretical specic capacity of the graphite anode (372 mA h g À1 ) can't meet people's requirements anymore. 53,78 One basic reason is that graphite is a single-electron-controlled anode, limiting the improvement of energy density. 79 According to the target set by the US Department of Energy's EV Everywhere Grand Challenge, 250-300 miles per charge for the next generation of electric-driven cars should be realized, placing great pressure on the vehicles' battery packs.…”
