SINTERING PREPARATION FOR POROUS PLAQUE CONTAINING HOLLOW NICKEL FIBER

The flexible plaque of porous nickel is crucially important for the cy cle life of nickel/cadmium, nickel/hydrogen and nickel/metal hydride b atteries. The use of hollow fiber can increase the flexibility of poro us plaque. The sintered porous plaque containing hollow nickel fiber i s fabricated by a traditional. slurry-scraping technology. The pore-cr eating agent and the pore-strengthening additive are applied to increa se the plaque porosity and optimize the pore structure. Nickel hydroxi de is used as a pore-strengthening agent and it also assists the gasif ication of organic pore-creating agent to some extent. The plaque poro sity reaches more than 88% when using thinner skeleton and large amoun t of hollow fiber.
