▎ 摘  要

NOVELTY - A gel comprises 10-20 pts. wt. cationic polyacrylamide, 60-80 pts. wt. self-made composite gel and 4-6 pts. wt. modified sodium alginate. The self-made composite gel is prepared by (a) taking 40-60 pts. wt. graphene oxide dispersion liquid, 10-15 pts. wt. microcrystalline cellulose and 30-40 pts. wt. chitosan dispersion liquid, ultrasonically dispersing, freezing into blocks with liquid nitrogen, and vacuum-freeze drying to obtain dry gel, and (b) grinding the obtained dried gel into powder. USE - Gel used for battery zinc paste. ADVANTAGE - The gel has low expansion rate, high water retention property and high discharge performance.
