Sodium-ion batteries (SIBs), as the next-generation high-performance electrochemical energy storage devices, have attracted widespread attention due to their cost-effectiveness and wide geographical distribution of sodium. As a crucial component of the structure of SIBs, the anode material plays a crucial role in determining its electrochemical per...
Newly designed all-electrochem-active thick electrode (similar to 500 mu m) with dual-continuous integrated skeletons of defective rutile-anatase TiO2 (D-R-A-TiO2) heterojunctions and carbon have been introduced to enhance efficient electron- ion transport for high-rate energy storage, which provides a new idea for low-temperature lithium storage. ...

Hard carbon is hard to be commercialized due to its low initial efficiency. The irreversible capacity loss usually consumes numerous lithium ions from the electrolyte, leading to an unexpected energy density attenuation. Therefore, effective pre-lithiation methods are extremely desired. Herein, a striking and simple pre-lithiated method was propose...

Sodium-ion batteries (SIBs) have emerged as one of the most promising candidates for next-generation energy storage systems because sodium is abundant in nature. The practical application of SIBs critically depends on developing robust electrode materials with high specific capacity and long cycling life, developing suitable anode materials is even...
In this study, we investigate the underlying origin of the high performance of PM6:Y6 organic solar cells. Employing transient optoelectronic and photoemission spectroscopies, we find that this blend exhibits greatly suppressed charge trapping into electronic intra-bandgap tail states compared to other polymer/non-fullerene acceptor solar cells, at...
