The Effect of PEG on Performance of Li_0.96Na_0.04Ni_1/3Co_1/3Mn_1/3O₂ as Cathode Material

Abstract:

Li_0.96Na_0.04Ni_1/3Co_1/3Mn_1/3O₂ with PEG400 or PEG2000 as additive was synthesized by coprecipitation method. Xray diffraction pattern reveals that both the products with PEG400 and PEG2000 are pure phase. Scanning Electron Microscopy shows that the average sizes of the powders are 100 nm and 80 nm, respectively. The sample with PEG 2000 has initial discharge capacity (205.8 Mah×g1) and the sample with PEG 400 exhibits good cycle performance with the capacity retention of 86.34 % after 90 cycles compared to that has no additive (167.6 mAh.g^-1 and 71.18 %) in the cut-off voltage of 2.0-4.5 V at 0.1 C rate. Therefore, PEG400 or PEG2000 as additive should improve the performance of Li_0.96Na_0.04Ni_1/3Co_1/3Mn_1/3O₂ cathode material.
