Whatman gf c microfiber filters

1,5-DNN and 1,5-NDA electrodes were prepared by mixing 1,5-DNN (or 1,5-NDA) compounds, graphene, and sodium alginate aqueous solution (15 mg⋅mL⁻¹) in a ratio of 6:3:1 (wt%) to form a slurry that was cast on aluminum foil by a doctor blade. The mixture was dried under vacuum at 50 °C for 8 h. CR 2032 coin-type cells were fabricated in a glovebox filled with argon (Ar) (O₂ < 0.1 ppm, H₂O < 0.1 ppm) using lithium metal as counter electrodes, PP separators, and electrolytes of 20 μL of 0.5 M LiClO₄ in DME or DME with 10% FEC (or VC). For the batteries using 0.5 M LiClO₄ in TEGDME as the electrolyte, Whatman GF/C microfiber filters were used as separators. Specifically, CR 2032 with several punched holes in a cathode was used to fabricate the cells operated in CO₂ atmosphere. All charge/discharge tests were conducted on a NEWARE battery test system in a voltage range of 3.0 V to 2.0 V, with a current density of 20 mA⋅g⁻¹. CV measurements were carried out on Solartron Analytical 1400 (AMETEK) at a scan rate of 0.01 mV⋅s⁻¹ between 3.0 V and 2.0 V. The self-discharge performance was evaluated by storing batteries for 0, 1, 2, and 3 mo before discharging, or for an intermittence of 7 d after partial discharging.
