In Situ Constructed TiO2 on Ti3C2‐MXene Cathode Enables Photo‐Assisted Zn‐Ion Hybrid Microsupercapacitors With High‐Energy Density

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A strategy has been developed for the in situ constructed of TiO2 nanoparticles on a Ti3C2‐MXene cathode, which is assembled with a zinc anode to form a photo‐assisted ZIH‐MSC device. The designed light‐assisted ZIH‐MSC device achieved a wide operating voltage (1.3 V) and battery‐level energy density (97 μWh cm−2, 1 mA cm−2), overcoming the limitations

Tuning Cation Disorder in LiNi0.5Mn1.5O4 via Room Temperature Continuous‐Flow Co‐Precipitation and Controlled Heat Treatment

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
LiNi0.5Mn1.5O4 (LNMO) precursors were produced at room temperature by Ambient Continuous Turbulent In‐line Mixing (ACTIM) at rates of up to 0.42 kg h−1. The final heat treatment step at 650, 700, or 750 °C, altered cation disorder and the electrochemical behavior of the LNMO cathodes, while the effect of adding MWCNTs to the electrodes, was also ...
