Delicate fabrication of ZnO/ZnCo₂O₄heterojunction HoMSs as anodes for lithium-ion batteries with high rate capability

Abstract

The high specific capacity of metal oxide can’t cover up its low electron and ion diffusion rate and large volume expansion as the anode of lithium-ion battery. The hollow multi-shelled...

Structural evolution and lithium-storage mechanism of the FeTiO3@Fe2TiO5 endogenous heterojunction

“…The nonuniform phase interfaces between FeTiO 3 and Fe 2 TiO 5 accelerate ion diffusion and electron transfer, thereby providing additional reaction sites for inducing transformation reactions. 4,40,41 Fig. 3(e) displays the charge–discharge curves of hetero-FTO at current densities ranging from 0.1 to 2 A g −1 , and the discharge capacities are 1,109, 750, 570, 394, and 251 mA h g −1 , respectively.…”

MoS2 Hollow Multishelled Nanospheres Doped Fe Single Atoms Capable of Fast Phase Transformation for Fast‐charging Na‐ion Batteries

“…Especially, as electrode materials for high energy density batteries, HoMS could effectively accommodate the volume change and the stress during chargingdischarging process, thus improving the cyclic stability. [25][26][27] Additionally, it could shorten the charge diffusion path, [28][29][30] thus improving the rate capability.…”

“…Wherein, hollow multishelled structure (HoMS) with multiple shells and interior cavities, has shown great promise in various application areas, including not only rechargeable batteries, [13–15] but also electromagnetic wave absorption, [16,17] catalysis, [18–20] sensor, [21,22] and drug delivery, [23,24] etc. Especially, as electrode materials for high energy density batteries, HoMS could effectively accommodate the volume change and the stress during charging‐discharging process, thus improving the cyclic stability [25–27] . Additionally, it could shorten the charge diffusion path, [28–30] thus improving the rate capability.…”
