The aqueous processing of lithium-ion battery (LIB) electrodes has the potential to notably decrease the battery processing costs and paves the way for a sustainable and environmentally benign production (and recycling) of electrochemical energy storage devices. Although this concept has already been adopted for the industrial production of LIB graphite anodes, the performance decay of cathode electrodes based on transition metal oxides processed in aqueous environments is still an open issue. In this study, we show that the addition of small quantities of phosphoric acid into the cathodic slurry yields Li[Ni0.33 Mn0.33 Co0.33 ]O2 electrodes that have an outstanding electrochemical performance in lithium-ion cells.
锂离子电池（LIB）电极的水相加工有显著降低电池加工成本的潜力，并为电化学储能装置的可持续和环境友好型生产（及回收利用）铺平了道路。尽管这一概念已被用于LIB石墨负极的工业生产，但在水相环境中加工的基于过渡金属氧化物的正极电极的性能衰减仍是一个未解决的问题。在本研究中，我们表明，向阴极浆料中添加少量磷酸可得到在锂离子电池中具有出色电化学性能的Li[Ni0.33 Mn0.33 Co0.33 ]O2电极。
