Abstract Graphene/platinum composite electrode (Pt-G/CFB) was prepared by one-step hydrothermal reduction method with three-dimensional carbon fiber brush as matrix. The analysis results showed that a large number of Pt nanoparticles and graphene were uniformly grown and coated on carbon fiber tow, and the grain size of Pt was about 3.1 nm; the composite electrode had large specific surface area and abundant mesoporous structure. Pt-G catalyst exhibited good catalytic performance and stability in oxygen reduction reaction (ORR). Seawater dissolved oxygen battery composed of composite electrode and Al alloy anode was tested for discharge. The battery has good discharge performance under low temperature, deficient oxygen and low current density conditions, and the maximum specific power reaches 197 mW/L.

Key words： seawater dissolved oxygen battery modified carbon fiber graphene-platinum composite catalyst oxygen reduction reaction constant current discharge
