Hengyu Ren, Jiaxuan Hu, Haocheng Ji, Yuxiang Huang, more

Advanced Materials > 36 > 40 > n/a - n/a

For LiCoO₂ (LCO) operated beyond 4.55 V (vs Li/Li⁺), it usually suffers from severe surface degradation. Constructing a robust cathode/electrolyte interphase (CEI) is effective to alleviate the above issues, however, the correlated mechanisms still remain vague. Herein, a progressively reinforced CEI is realized via constructing Zr─O deposits (ZrO₂ and Li₂ZrO₃) on LCO surface (i.e., Z‐LCO). Upon cycle,...

In practical applications, LiCoO₂ (LCO) cathode is usually charged with a constant current plus constant voltage (CC+CV) procedure to obtain higher capacity delivery. However, the harsh condition upon CC+CV procedure causes the accelerated capacity decay of LCO. Herein, the fading mechanism of LCO cycling upon CC+CV procedure at 4.6 V versus Li/Li⁺ is first revealed. Comparing with a pure CC charging,...

Advanced Materials > 36 > 6 > n/a - n/a

The rapid development of modern consumer electronics is placing higher demands on the lithium cobalt oxide (LiCoO₂; LCO) cathode that powers them. Increasing operating voltage is exclusively effective in boosting LCO capacity and energy density but is inhibited by the innate high‐voltage instability of the LCO structure that serves as the foundation and determinant of its electrochemical behavior...

Advanced Functional Materials > 33 > 46 > n/a - n/a

Recently, lots of researches have focused on enhancing the structure stability of LiCoO₂ (LCO) at a cutoff voltage of 4.6 V (vs Li/Li⁺) at room temperature. However, the high temperature (≥45 °C) performances are more significant for practical applications. Herein, the mechanism of unsatisfactory structure stability of LCO at 45 °C via comparing a commercial LCO (C‐LCO) and a surface optimized LCO...

Vegetation restoration has been recognized as an effective ecological measure to mitigate soil heavy metal contamination in open‐pit mining areas. However, little is known about the processes of accumulation and translocation of heavy metals in naturally restored soil–plant systems in these areas. In this study, soil and plant samples were collected from three natural restoration sites of different...
