    • The present invention provides a method for the processing of particles of metal phosphates or particles of mixed metal phosphates and in particular lithiated metal phosphates and mixed metal phosphates. The processing occurs, for example using a mechanofusion system as depicted in FIGS. 1 and 2. In general, the powder materials are placed in a rotary container and are subjected to centrifugal force and securely pressed against the wall of the container. The material then undergoes strong compression and shearing forces when it is trapped between the wall of the container and the inner piece of the rotor with a different curvature (FIG. 2). Particles of the material are brought together with such force that they adhere to one another. In the mechanofusion system, as indicated in FIG. 2, the powder material is delivered through slits on the rotary walls. It is carried up above the rotors by the rotor-mounted circulating blades. Subsequently, the material returns again to the rotors where it is are subjected to strong compression and shearing forces from the inner pieces of the rotor. This cycle of both three-dimensional circulation and effective compression/shearing of the powder material is repeated at high speeds, thereby forming it into a composite electroactive material (powder).
    • 本发明提供了一种处理金属磷酸盐或混合金属磷酸盐颗粒,特别是锂化金属磷酸盐和混合金属磷酸盐的颗粒的方法。 处理发生,例如使用如图1和2所示的机械融合系统。 通常,将粉末材料放置在旋转容器中并经受离心力并且牢固地压靠在容器的壁上。 然后当材料以不同的曲率被捕获在容器的壁和转子的内部片之间时,该材料经受强的压缩和剪切力(图2)。 材料的颗粒以这样的力相互结合在一起,使得它们彼此粘附。 在机械融合系统中,如图1所示。 如图2所示,粉末材料通过旋转壁上的狭缝输送。 由转子安装的循环叶片承载在转子上方。 随后,材料再次返回到转子,在转子处受到来自转子的内部片的强烈的压缩和剪切力。 以高速重复粉末材料的三维循环和有效压缩/剪切的循环,从而将其形成为复合电活性材料(粉末)。
