CMC as a binder in LiNi0.4Mn1.6O4 5V cathodes and their electrochemical performance for Li-ion batteries

Résumé

Aqueous processing would reduce the costs and toxicity associated with the making of the composite electrode. In the present study, carboxymethyl cellulose is used as a binder for 5V cathode material LiNi"0"."4Mn"1"."6O"4. Compared with electrodes using polyvinylidene difluoride binder, CMC-based LiNi"0"."4Mn"1"."6O"4 electrodes display a better discharge capacity at all rates. At 0.2C, the discharge capacity is close to the theoretical capacity (146mAhg^-^1) and the self-discharge is 10% lower. Polyvinylidene difluoride can be efficiently replaced by carboxymethyl cellulose for LiNi"0"."4Mn"1"."6O"4 in terms of electrochemical performance and brings the advantage of an environment friendly and low cost electrode processing.
