Hierarchical porous microspheres consisted of interconnected Co3O4 and graphene nanosheets were prepared using a one-step hydrothermal method, which led to improvement in electrochemical performance towards glucose oxidation

Namyong Kim, Yoon Myung, Hyunseo Kang, Jae-Won Lee, MinHo Yang*, Effects of Methyl Acetate as a Co-Solvent in Carbonate-Based Electrolytes for Improved Lithium Metal Batteries, ACS Applied Materials & Interfaces, 2019, 11, 338446–33849.

The rate and temperature performance of lithium metal batteries were studied in carbonate-ester based electrolytes. In this work, aliphatic ester (i.e., methyl acetate (MA)) play a significant role in formation of LiF-rich surface film on Li metal anode, which enables to deliver the high capacity with excellent capacity retention even at high charge/discharge rate.
