Building an artificial solid electrolyte interphase on spinel lithium manganate for high performance aqueous lithium-ion batteries.

Spinel lithium manganate (LiMn2O4) is a promising cathode for aqueous lithium-ion batteries (ALIBs). However, due to Mn dissolution and the Jahn-Teller effect it suffers from fast capacity fading, insufficient rate capability, and low overcharge resistance. Herein, a ∼2-3 nm artificial solid electrolyte interphase (SEI) layer (lithium polyacrylate, LiPAA) is constructed on the commercial LiMn2O4 (LiPAA@LiMn2O4).

Constructing mesoporous phosphated titanium oxide for efficient Cr(III) removal.

Heavy metal removal by environmental-friendly nanostructured TiO adsorbent is a promising strategy to facilitate wastewater treatment. Here, a boiling water synthetic approach is explored to prepare mesoporous phosphated TiO (PTO) used for Cr(III) adsorption in polluted water. We obtain mesoporous 8-PTO (synthesized with 8% molar ratio of HPO) with a high specific surface area (278 m/g), narrow size distribution (<5 nm), low pH (pH of zero point of charge) value (∼1.
