| titleOfInvention | Novel nickel-hydrogen battery diaphragm |
| abstract | The invention relates to a diaphragm for batteries, in particular to a novel nickel-hydrogen battery diaphragm. The novel nickel-hydrogen battery diaphragm comprises a diaphragm base fabric and sulfonic acid group. The sulfonic acid group is uniformly grafted on the surface of the diaphragm base fabric by sulfonation. The novel nickel-hydrogen battery diaphragm further comprises an acrylic acid monomer. The acrylic acid monomer is uniformly grafted on the surface of the diaphragm base fabric through a chemical grafting reaction. The diaphragm base fabric is prepared from polyolefin sheath-core type fiber or polypropylene fiber or polyolefin sheath-core type fiber and polypropylene fiber. The diaphragm base fabric is shaped by a wet process paper-making technology or a dry process carding technology and is reinforced by spunlace process. The novel nickel-hydrogen battery diaphragm disclosed by the invention has the characteristics of high chemical stability, strong oxidation resistance and high strength. The diaphragm has permanent hydrophilicity and liquid maintaining performance, improves ionic migration capacity and ion exchange capacity, effectively reduces internal resistance, improves large current discharging capacity and has excellent charge maintaining capacity. |
