Abstract
A flexible multifunctional cross-linking adhesive, a preparation method therefor and an application thereof. The adhesive uses guar gum and carboxyl styrene butadiene rubber as raw materials, and is formed by intermolecular cross-linking between hydroxyl groups rich in the guar gum and carboxyl groups contained in the carboxyl styrene butadiene rubber to form a flexible multifunctional cross-linked network. Compared to the prior art, the water-based adhesive is a flexible cross-linking adhesive that has a strong bonding force, high mechanical strength, and no cracking due to tensile deformation, and is insoluble in a battery electrolyte. The adhesive may effectively accommodate the volume effect of a sulfur positive electrode and keep the positive electrode structure intact during a cycling operation. At the same time, the adhesive has significant advantages such as environmental friendliness and being low cost. The compacted sulfur positive electrode has a simple preparation process and has relatively large application prospects.
