The utility model discloses an eye cane raw material straightening equipment, including steam straightening structure, steam straightening structure intercommunication steam recovery structure, steam straightening structure is adjusted the position of hot roll straightening subassembly through telescopic structure, steam straightening structure includes bottom box, and the straightening box is communicated in bottom box upside, and the left side of straightening box is fixed with first material guide roller, and steam straightening subassembly is installed in straightening box and is dismantled, and steam straightening subassembly includes steam box, and the position of steam spray header and first inverted U shape board second material guide roller on first support plate is adjusted through telescopic structure telescopic of steam box, and second material guide roller is located between steam spray header, and steam spray header is connected with steam generator through first gas pipe, and the downside of second material guide roller is provided with third material guide roller, and this eye cane raw material straightening equipment is handled to the high temperature steam straightening of the serious deformation and the relatively dry eye cane rattan cane through the setting of steam straightening subassembly, and the straightening of eye cane rattan cane is carried out again through the setting of hot roll straightening subassembly.

The invention relates to an electrode assembly, a battery monomer, a battery and a power utilization device, the electrode assembly comprises pole pieces and diaphragms, each diaphragm comprises a main body section, and the pole pieces and the main body sections of the diaphragms are stacked and wound to form an electrode main body; at least one axial end of the electrode main body is provided with a tab protruding out of the main body section; the at least one layer of diaphragm comprises a first extension section connected with the main body section, and the first extension section is wound outside the electrode main body for at least one circle; the first extension section is provided with a convex part protruding out of the main body section along the axial end part, and at least part of the convex part is folded towards one side close to the center of the electrode main body so as to cover the edge part of the tab at the corresponding end. The first extension sections are wound at all positions of the electrode main body in the axial direction, so that the radiuses or diameters of all parts of the electrode assembly can be ensured to be the same, all parts of the electrode assembly are uniformly expanded when the electrode assembly is expanded, the outer ring pole piece is not easy to break, and the use performance of the battery monomer is ensured.
