Electrochemical behavior of prepared electrodes was examined in a coin cell (CR2032, Hohsen Corp.) configuration employing 14 mm lithium metal disc (Honjo) as the negative electrode separated by a porous membrane (GF/A, Whatman) soaked with 200 µL of LP30 electrolyte (1 M LiPF6 in a 1:1 vol.% mixture of ethylene carbonate/dimethyl carbonate (EC:DMC)).
