Abstract
An anode material for Li-ion batteries is prepared using the following steps: (a) 2,2-Bis[4-(4-aminophenoxy) phenyl] hexafluoropropane, 3,3',4,4'-Biphenyltetracarboxylic dianhydride and graphene oxide are mixed to prepare PAA/GO, and then acetic anhydride and triethylamine are added to prepare concentrate; (b) PI-rGO composite is obtained by high-temperature firing; (c) N-Methylpyrrolidone, Pyralene, Polyvinylidene fluoride, Nanoscale silicon particles, Carbon nano tubes (CNT) and Beta-Cyclodextrin are added to obtain conductive paste; and (d) after being dried and cooled, the required anode materials are obtained by slicing on a manual microtome. The resulting anode materials have good lithium-ion conductivity and capacity retention. The cyclodextrin is stated to be used for pore formation and the combination of pyralene and PVDF as binder coats the Si particles effectively and prevents silicon falling off surfaces during charging and discharging. The pores created in the material also ensure effective mixing of the reduced graphene oxide and CNTs in the binder.
