Ue, Makoto published the artcileMaterial balance in the O2 electrode of Li-O2 cells with a porous carbon electrode and TEGDME-based electrolytes, COA of Formula: C10H22O5, the main research area is O2electrode porous carbon electrode TEGDME electrolyte.
This work figures out the material balance of the reactions occurring in the O electrode of a Li-O cell, where a Ketjenblack-based porous carbon electrode comes into contact with a tetraethylene glycol di-Me ether (TEGDME)-based electrolyte under more practical conditions of less electrolyte amount and high areal capacity. The ratio of electrolyte weight to cell capacity (E/C, g A h) is a good parameter to correlate with cycle life. Only 5 cycles were obtained at an areal capacity of 4 mA h cm (E/C = 10) and a discharge/charge c.d. of 0.4 mA cm, which corresponds to the energy d. of 170 W h kg at a complete cell level. When the areal capacity was decreased to half (E/C = 20) by setting a c.d. at 0.2 mA cm, the cycle life was extended to 18 cycles. However, the total elec. charge consumed for parasitic reactions was 35 and 59% at the first and the third cycle, resp. This surprisingly large amount of parasitic reactions was suppressed by half using redox mediators at 0.4 mA cm while keeping a similar cycle life. Based on byproduct distribution, we will propose possible mechanisms of TEGDME decomposition and report a water breathing behavior, where HO is produced during charge and consumed during discharge.
