Embodiment

[0021] Positive electrode slurry preparation: the mass percentage of each main raw material is: spherical nickel hydroxide: CoO: TiO 2 : Y 2 o 3 : Nickel powder: PTFE: The mass percent of CMC is: 85%: 6%: 2%: 1.5%: 3%: 1.2%: 1.3%.

[0022] Negative electrode slurry preparation: use LaNi5 type hydrogen storage alloy powder (Inner Mongolia Xiaoke B5A-180), soak in boiling 5.5M KOH aqueous solution for 40 minutes, take it out and rinse it repeatedly in deionized water for 3 times, drain it, and dry it in vacuum Use after drying in the box for 8 hours. The mass percentages of the main materials of the negative electrode ingredients are: 96% of hydrogen storage alloy powder, 3% of nickel powder, and 2% of PTFE.

[0023] After the positive and negative electrode slurry is prepared, follow the figure 1 As shown in the process flow, AA-1500P high-power batteries are produced, and the size of the positive plate 2 is: 95mm×43mm×0.65mm (length×width×thickness). Dimensions of the neg...

Abstract

In the battery shell there are pole pieces of anode and cathode. The anode paste is mainly composed of nickel hydroxide. In the supplementary materials there are CoO, TiO2, and Y2O2 as additive. The cathode paste is mainly composed of hydrogen storage alloy powder. The pastes are coated on current collector to form pole pieces of anode and cathode. The anode piece, diaphragm, and cathode piece are rolled to form cell core. The electrolyte is filled into the battery shell. The said cathode piece is longer than the one of anode in rolling direction, and is 1-4mm wider than the one of anode, so that the cathode piece in outmost layer contacts the inner wall of battery shell, and the bottom of cathode is bonded with the bottom of battery shell by welding.

Description

technical field [0001] The invention relates to a cylindrical nickel-hydrogen secondary battery and a manufacturing method thereof. Background technique [0002] In recent years, people have paid more and more attention to issues such as urban air quality and the earth's oil resource crisis, and the calls for environmental protection and energy conservation have become increasingly louder, prompting people to attach great importance to the development of electric vehicles and related technologies. The United States, France, China's Shanghai, Beijing Municipalities and other cities have successively passed legislation to restrict fuel vehicles and vigorously develop electric vehicles. Secondly, the production of mobile electric tools in China accounts for 30% of the world's total output, and there are a large number of exports to Europe and the United States every year. From July 2006, Europe will ban the import of electromechanical products equipped with nickel-cadmium or le...
