Tin-based electrode s offer high theoretical capacities in lithium ion batteries, but further commercialization is strongly hindered by the poor cycling stability. An situ reduction method developed to synthesize SnO2 quantum dots@graphene oxide. This approach achieved oxidation of Sn2+ and graphene At 2 A g−1, a capacity retention 86% obtained even after 2000 cycles. As service our authors readers, this journal provides supporting information supplied authors. Such materials are peer...
Transition metal oxides have attracted much interest for their high energy density in lithium batteries. However, the fast capacity fading and low power still limit practical implementation. In order to overcome these challenges, one-dimensional yolk–shell nanorods been successfully constructed using manganese oxide as an example through a facile two-step sol–gel coating method. Dopamine tetraethoxysilane are used precursors obtain uniform polymer silica layer followed by converting into...
Developing efficient, stable, and low-cost catalysts for oxygen evolution reaction (OER) is highly desired in water splitting metal–air batteries. Transition metal–organic frameworks (MOFs) have emerged as promising been intensively investigated especially due to their tunable crystalline structure. Unlike traditional strategies of tuning the morphology well-crystalline MOFs, low-crystalline bimetallic MOFs are constructed via inducing exotic metal ions, formation process revealed by...
Zinc metal batteries are strongly hindered by water corrosion, as solvated zinc ions would bring the active molecules to electrode/electrolyte interface constantly. Herein, we report a sacrificial solvation shell repel from and assist in forming fluoride-rich, organic-inorganic gradient solid electrolyte (SEI) layer.

On one hand, LCNF provides enough strength (43.7 MPa) at relative low porosity (52.2%) enable diffusion limited suppression, while, on other MXene serves as gating layer,...
The proton, as the cationic form of lightest element-H, is regarded most ideal charge carrier in "rocking chair" batteries. However, current research on proton batteries still at its infancy, and they usually deliver low capacity suffer from severe acidic corrosion.
