Abstract: An electrode active layer is disclosed that includes a network of high aspect ratio carbon elements (e.g., carbon nanotubes, carbon nanotube bundles, graphene flakes, or the like) that provides a highly electrically conductive scaffold that entangles or enmeshes the active material, thereby supporting the layer. A surface treatment can be applied to the high aspect ratio carbon elements to promote adhesion to the active material and any underlying electrode layers improving the overall cohesion and mechanical stability of the active layer. This surface treatment forms only a thin (in some cases even monomolecular) layer on the network, leaving the large void spaces that are free of any bulk binder material and so may instead be filled with active material. The resulting active layer may be formed with excellent mechanical stability even at large thickness and high active material mass loading.

Abstract: A processing method of stator, comprising the following steps: Step 100: Forming a stator blank out of a standard bar stock through cold extruding; Step 200; Turning the excircle, the end faces and the sealing groove of the stator blank prepared in step 100, so as to obtain a semi-finished product of stator; Step 300: Performing precision broaching on the inner bore of the semi-finished product of stator prepared in step 200, so as to obtain a finished product of stator. The processing method of stator provided in this invention has the following advantages: The blank cutting allowance is small. The broach is simple to manufacture and of low grinding cost. It is not necessary to turn the internal bore, and the parts have sound heat-treatment performance, and the fatigue resistance of material is improved. Cold extruding technology is adopted so that fluidity of the material is improved.
