Enhanced reversible capability of a macroporous ZnMn₂O₄/C microsphere anode with a water-soluble binder for long-life and high-rate lithium-ion storage

Abstract

ZnMn2O4 and carbon are mixed uniformly to form macroporous ZnMn2O4/C microspheres consisting of many tiny nanoparticles. The macroporous ZnMn2O4/C microsphere anode with a CMC binder shows superior cycle performance in lithium-ion batteries.

Sodium ion intercalation and multi redox behavior of a Keggin type polyoxometalate during [PMo10V2O40]5−to [PMo10V2O40]27−as a cathode material for Na-ion rechargeable batteries

“…Owing to the economic and energy concerns, advancements in energy storage and conversion devices are mostly necessary in recent modernization and for global population as energy storage devices impose their advantages in portable electronic devices, gadgets, electric vehicles (EVs), and hybrid electric vehicles (HEVs). 1 Among the various energy storage devices, Liion batteries 2,3 meet the huge energy demands with long cycle life 4,5 and high energy density. [6][7][8][9] Despite these advantages in Liion batteries (LIBs), the growing demand is limited by low reserves, uneven distribution of the source, high costs and safety parameters.…”

Hierarchical Porous MoS2/C Nanospheres Self-Assembled by Nanosheets with High Electrochemical Energy Storage Performance

“…Commercial MoS 2 presents initial charge/discharge specific capacities of 671.70/952.52 mAh g −1 , which is far from the MoS 2 /C composites (865.54/1307.77 mAh g −1 ). This is because the existence of carbon in MoS 2 /C improve the conductivity and the surface/interfacial storage of Li originated from the porous nanosphere structure and the reversible formation/decomposition of polymeric gel-like film (SEI) [38]. After 100 cycles, the MoS 2 /C and MoS 2 anodes show discharge specific capacities of 587.18 and 350 mAh g −1 with high CE of approximate 99%.…”

Fabrication of Silica/Sulfur@Polyaniline Spheres with Radial Mesochannels as Enhanced Cathode Materials for High‐Performance Lithium−Sulfur Batteries

“…Unfortunately, many of the synthetic nonpolar carbon host materials have low binding energy with polar LiPSs, limiting the recyclic stability of Li−S batteries . Recently, many reports have presented that metal oxides, such as TiO 2 , CoO, MnO, SiO 2 , and Ti 4 O 7 , and sulfur cathodes, can achieve high electrochemical performance from the strongly adsorptive metal oxides. However, most of them have poor electrical conductivities.…”
