Abstract Here, we demonstrate facile water-processable and sprayable electrode fabrication methods for LiFePO4/graphene hybrid cathodes in LIBs, without using an organic solvent. The multi-functionality of graphene oxide (GO), as a dispersant, binder, and precursor for the conductive graphene, was exploited in this fabrication process. Additional polymeric binders or conductive carbons were unnecessary. At high current rates, this water-processed LiFePO4/reduced graphene oxide (LFP/rGO) can store a larger amount of charges than conventional LFP cathodes produced by the previously formulated organic slurry-based blade coating method. The LFP/rGO electrode consisting of 80 wt.% LFP and 20 wt.% rGO showed capacity of 37 mA h g−1 at a very high current rate (2040 mA g−1). In contrast, the conventional LFP–based electrodes fabricated with poly(vinylidene fluoride), and carbon black in an organic solvent, exhibited negligible capacity (

用于高功率锂离子电池的可水处理、可喷涂的 LiFePO4/石墨烯混合阴极

摘要 在这里，我们展示了 LIB 中 LiFePO4/石墨烯混合阴极的简便的可水处理和可喷涂的电极制造方法，而无需使用有机溶剂。在该制造过程中利用了氧化石墨烯 (GO) 作为导电石墨烯的分散剂、粘合剂和前体的多功能性。不需要额外的聚合物粘合剂或导电碳。在高电流速率下，这种水处理的 LiFePO4/还原氧化石墨烯 (LFP/rGO) 可以存储比以前制定的基于有机浆料的刮刀涂层方法生产的传统 LFP 阴极更多的电荷。由 80 wt.% LFP 和 20 wt.% rGO 组成的 LFP/rGO 电极在非常高的电流速率（2040 mA g-1）下显示出 37 mA h g-1 的容量。相比之下，
