AI Technical Summary
Existing nickel hydroxide electrode materials suffer from small specific surface area and poor conductivity, and existing technologies neglect the impact of catalytic performance during the composite improvement process.
Using carbon-based braided material as a carrier, a nickel layer is formed by hydrothermal chemical bath deposition. Combined with heat treatment and electrodeposition, a nickel-based hollow microtube braided composite electrode is prepared, forming a mutually doped structure of nickel hydroxide and metallic nickel, which increases the specific surface area and improves conductivity and catalytic performance.
The prepared nickel-based hollow microtube braided composite electrode has a large specific surface area, good conductivity and electrochemical activity, and good mechanical properties, making it suitable for fuel electrodes.
