Abstract: The present application provides a dispersant, and a conductive slurry and a preparation method thereof and use thereof. The dispersant includes any one or a combination of at least two of compounds having a structure represented by Formula I. The compounds having the structure represented by Formula I include both a polyester chain segment and a polyaniline chain segment, and have a strong adsorption effect on a conductive agent, and also good affinity for organic solvents, thereby effectively preventing agglomeration of the conductive agent in the organic solvents and improving the dispersity of the conductive agent in the organic solvents, so that the obtained conductive slurry has high conductivity, and has both low viscosity and high solid content, and is suitable for use in lithium-ion batteries.

Abstract: The present application provides a negative electrode binder and a preparation method thereof and an application thereof. Raw materials for preparing the negative electrode binder include a soft monomer, a hard monomer, a urethane bond-containing acrylate monomer, an emulsifier, an initiator and water; and the urethane bond-containing acrylate monomer is prepared by a reaction of a small molecule diol monomethyl ether and a diisocyanate, and followed by end-capping with an acrylate containing a terminal hydroxyl group. The negative electrode binder has characteristics such as high bonding performance, good flexibility, resistance to electrolyte swelling and high temperature stability.

Abstract: The present invention provided a simple three-step approach based on the combinational induction with activin A, all-trans retinoic acid and, optionally, other maturation factors which are able to induce embryonic stem cells to differentiate into insulin-producing cells. A kit used to induce embryonic stem cells to differentiate into insulin-producing cells was also provided.
