    • Disclosed is a method of preparing an electrode material using a hydrothermal synthesis process, including (a) mixing an electrode material precursor and high-temperature, high-pressure water so as to react with each other, thus producing an electrode material-containing stream, (b) cooling the electrode material-containing stream through heat exchangers, (c) reducing the pressure of the cooled electrode material-containing stream using a pressure reducer, and (d) concentrating the electrode material-containing stream at the reduced pressure using a concentrator, thus producing a concentrated electrode material. According to this invention, synthesis conditions are maintained stable, continuous mass production is possible, and operation stability of the synthesis process can be ensured. Particularly, the concentrator is disposed downstream of the pressure reducer and thus a low-pressure concentrator can be applied, thereby lowering the preparation cost, and increasing heat recovery efficiency by using a plurality of heat exchangers to thus attain energy saving effects.
    • 公开了一种使用水热合成方法制备电极材料的方法,包括(a)将电极材料前体和高温高压水混合以便彼此反应,从而产生含电极材料的流, (b)通过热交换器冷却含电极材料的流,(c)使用减压器降低含冷却电极材料的流的压力,和(d)使用电极材料的流在减压下浓缩, 浓缩器,从而产生浓缩的电极材料。 根据本发明,合成条件保持稳定,连续批量生产是可能的,并且可以确保合成过程的操作稳定性。 特别地,集中器设置在减压器的下游,因此可以施加低压浓缩器,从而降低制备成本,并且通过使用多个热交换器来提高热回收效率,从而获得节能效果。
