Cathode electrolyte interphases (CEIs) are critical to the cycling stability of high-voltage cathodes for batteries, yet their formation mechanism and properties remain elusive. Here we report that compositions CEIs largely controlled by abundant species in inner Helmholtz layer (IHL) can be tuned from material aspects. The IHL LiCoO2 (LCO) was found alter after charging, with a solvent-rich environment results fragile organic-rich CEIs. By passivated spinel Li4 Mn5 O12 coating, achieve an...
Li-rich Mn-based oxides (LRMOs) are promising cathode materials for next-generation lithium-ion batteries (LIBs) with high specific energy (≈900 Wh kg-1 ) because of anionic redox contribution. However, LRMOs suffer from issues such as irreversible release lattice oxygen, transition metal (TM) dissolution, and parasitic cathode-electrolyte reactions. Herein, a facile, scalable route to build homogenous ultrathin Li2 TiO3 (LTO) coating layer on the primary particles LRMO through molten salt...
The key challenge for high-performance sodium-ion batteries is the exploitation of appropriate electrode materials with a long cycling stability and high rate capability. Here, we report Sb2S5 nanoparticles (∼5 nm) uniformly encapsulated in three-dimensional (3D) porous graphene foam, which were fabricated by facile hydrothermal coassembly strategy, as anode material batteries. as-prepared composite can be directly used electrodes without adding binder or current collector, exhibiting...
Ni-rich layered oxides with chemical formula of LiNixCoyMnzO2 or LiNixCoyAlzO2 (x + y z = 1, x ≥ 0.6) have been considered as promising cathode materials for lithium-ion batteries (LIBs) because their high specific capacity (≥180 mAh g–1) and acceptable manufacture cost. However, the problems associated Ni content severely restrict large-scale applications. In this review, we summarize recent advances in oxide particle LIBs. We begin introduction structure, redox mechanism, oxides, mainly...

Abstract Nonstoichiometry plays an important role in determining physicochemical properties such as conductivity, activity, and stability due to the composition‐induced change phase, local atomic environment, electronic structure. A variety of materials with nonstoichiometry have emerged electrochemical energy conversion storage, which necessitates a solid understanding their formation mechanism structure–function relationship. This review presents summary progress made this emerging field,...

Microbial fuel cell (MFC) has been attracting extensive interest, because it can be used for electricity generation and concurrently wastewater treatment. Yet, the MFC performance remained limited due to sluggish electron-transfer kinetics hence high overpotential of oxygen reduction reaction (ORR) at cathode.
