Abstract: The present disclosure provides a positive electrode sheet including a positive electrode current collector and a positive electrode material layer formed on the positive electrode current collector. The positive electrode sheet has a potential range of greater than or equal to 4.25 V with respect to metal lithium. The positive electrode material layer includes a positive electrode active material doped or coated with metal elements and a compound represented by formula I. The positive electrode sheet satisfies following conditions: 0.3≤m+n100k≤59; and 50 ≤ m ≤ 10000, 50 ≤ n ≤ 10000, 2.8 ≤ k ≤ 3.8; where m is a content of the compound represented by the formula I in the positive electrode material layer; n is a total content of the metal elements doped and coated in the positive electrode material layer; and k is a compacted density of the positive electrode material layer. A solution obtained after ultrasonically shaking the positive electrode sheet in a solvent is subjected to a liquid chromatography-mass spectrometer (LC-MS) analysis, and a characteristic peak appears in a region having a retention time of 6.5 min to 7.5 min.

Abstract: In accordance with the present invention, there is provided herein a method of increasing the strength of wet glass fiber mats prepared by the wet-laid process. The wet-strength of such freshly prepared glass fiber mats are improved in this invention by treating the wet mat with a dilute solution of an anionic polyelectrolyte. As a feature of the invention, the wet-strength of such mats are increased substantially so that they may be conveniently handled and transferred, even manually, for further processing, e.g. for applying binders and drying, into the finished glass fiber mat product.

Abstract: A method of separating acrylic acid from an aqueous solution containing acrylic acid, comprising adding a salt that eliminates the eutectic point between acrylic acid and water, for example an alkali metal salt, in particular sodium chloride, to the aqueous solution in an amount sufficient to saturate the aqueous solution, and fractionally crystallising the aqueous solution to obtain acrylic acid. 
<??>The fractional crystallisation is preferably carried out in from three to six stages, and leads to a product which contains more than 99% of acrylic acid and less than 0.02% by weight of added salt, for example sodium chloride.

Abstract: A multiple longitudinal traversing shed weaving apparatus comprises a weaving rotor having beat-up or beating elements for the inserted weft threads and shed-retaining elements which retain the warp threads, throughout a predetermined path, in their upper shed position or lower shed position. Each intermediate space between neighboring beat-up elements has operatively associated therewith a respective shed-retaining element which determines the upper shed position or lower shed position. Control means are arranged forwardly of the weaving rotor, viewed in the direction of travel of the warp threads, and serve for the lateral deflection and selective allocation of the warp threads at a shed-retaining element which determines the upper shed position or lower shed position. The control means possesses stroke adjusting elements in the weft direction which are constituted by rods or bars extending in the weft direction. These rods are connected with an actuation device of the type used in a conventional dobby loom.
