Problems solved by technology

[0002] At present, in the process of charging and discharging alkaline nickel-metal hydride and nickel-cadmium secondary batteries, nickel foam plates are usually used as the skeleton material of the positive plate of the battery. The nickel foam plate is a nickel fibrous foam formed by nickel-plating plastic foam. , dense and interconnected spaces and channels are ideal carriers for filling nickel active materials, but because the state of foamed nickel is a fibrous foam, it is difficult to weld the tabs; in addition, the price of metallic nickel is relatively high, thus lead to higher battery costs

Embodiment 1

[0021] A kind of manufacture technology that uses nickel-plated steel strip to make nickel-metal hydride, nickel-cadmium battery positive plate, its process steps are as follows:

[0022] 1. Stir 48% nickelous hydroxide, 5% cobaltous oxide, and 18% graphite together;

[0023] 2. Add 18% glue and 11% pure water and stir evenly at room temperature to form positive plate slurry;

[0024] 3. Use the pulping furnace to coat the slurry on the nickel-plated steel strip with a thickness of 0.04-0.08. The thickness of the steel strip is determined according to the customer's requirements. The drying temperature of the pulping furnace is 120°C, and the pulping speed is 90m / Hour;

[0025] 4. Use a rolling machine to roll the dried plate, the rolling gap is: 0.4 ~ 0.7mm; the actual rolling gap is subject to the actual product requirements;

[0026] 5. Use a cutting machine to cut out a positive plate of a fixed size;

[0027] 6. Weld the positive tab on the positive plate.

Embodiment 2

[0029] A kind of manufacturing technology that uses nickel-plated steel net to make nickel-metal hydride, nickel-cadmium battery positive plate, and its processing steps are as follows:

[0030] 1. Stir 50% nickelous hydroxide, 5% cobaltous oxide, and 19% graphite evenly together;

[0031] 2. Add 17% glue and 9% pure water and stir evenly at room temperature to form positive plate slurry;

[0032] 3. Use a pulping furnace to coat the slurry on a nickel-plated steel mesh with a thickness of 0.2-1.0mm. The thickness of the steel mesh is determined according to customer requirements. The drying temperature of the pulping furnace is 120°C, and the pulping speed is 90m / Hour;

[0033] 4. Use a rolling machine to roll the dried plate, the rolling gap is: 0.4 ~ 0.7mm; the actual rolling gap is subject to the actual product requirements;

[0034] 5. Use a cutting machine to cut out a positive plate of a fixed size;

[0035] 6. Weld the positive tab on the positive plate.

Abstract

This invention discloses a nickel hydrogen, the nickel cadmium cell positive plate manufacture craft, its craft step as follows: 1. stir uniformly 40-50% hydrogen nickelous oxide, 2-5% coalhouse oxide,10-20% graphite evenly; 2. add 15-20%glue water as well as 8 -15% pure water evenly and stir them to positive plate pulp; 3.coat the pulp on nickel plated steel net whose thickness is 0.2-1.0mm or nickel plated steel whose thickness is: On 0.04-0.08 by using pulp coating oven whose drying temperature is 100-140degree C and pulp coating speed is 80-100m / hour; 4. roll the pole plate by using roller, rolling gap will be: 0.4-0.7mm, traction speed is 80-100m / hour; 5. cut out the positive plate with fixed size; 6. Weld the positive electrode ear on the positive electrode plate. Advantages: flowline production, raised production efficiency and reduced production cost.

Description

technical field [0001] The invention relates to a manufacturing process of a battery positive plate, in particular to a manufacturing process of a nickel-hydrogen and nickel-cadmium battery positive plate Background technique [0002] At present, in the process of charging and discharging alkaline nickel-metal hydride and nickel-cadmium secondary batteries, nickel foam plates are usually used as the skeleton material of the positive plate of the battery. , dense and interconnected spaces and channels are ideal carriers for filling nickel active materials, but because the state of foamed nickel is a fibrous foam, it is difficult to weld the tabs; in addition, the price of metallic nickel is relatively high, thus This leads to an increase in battery cost. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a manufacturing process for the positive plate of nickel-hydrogen and nickel-cadmium batteries with ...
