Figure 6: Li-oxygen battery performance using MWCNT, S-MWCNT and E-MWCNT cathode films, tested with 1 M LiTFSI in DME under 1.5 atm of O2.
From: Biotemplating pores with size and shape diversity for Li-oxygen Battery Cathodes
(a) The schematic showing the proposed distribution of discharge products in MWCNT and E-MWCNT cathodes. (b) The first full discharge capacity tested at 2 A/ge. Each cell was fully soaked in electrolyte for 1–2 h before the battery measurement. (c) Coulombic efficiencies of Li-oxygen battery with MWCNT, S-MWCNT and E-MWCNT cathodes for their first four deep cycles at 2–4.6 V of voltage windows tested at 1 A/ge. Inset: discharge (filled) and charge (empty) capacities of each cycles.
