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

The manufacture craft of a kind of ni-mh or nickel-cadmium cell positive plate

Technical field

The present invention relates to a kind of manufacture craft of battery positive plate, the manufacture craft of particularly a kind of ni-mh or nickel-cadmium cell positive plate

Background technology

In present alkaline ni-mh or the NI-G charging/discharging of secondary cell process, usually use the framework material of porous nickel mesh as battery positive plate, porous nickel mesh is the fibrous foams of nickel that plastic foam forms through Nickel Plating Treatment, it has space and passage even, closely knit and that interrelate, it is the ideal carrier of filling nickel hydroxide active material, because the state of nickel foam is fibrous foams, so the welding of lug is difficult; In addition, the price of metallic nickel is higher, thereby causes the battery cost to improve.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of low cost of manufacture, intensity height, the manufacture craft of simple ni-mh of technology or nickel-cadmium cell positive plate.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

The manufacture craft of a kind of ni-mh or nickel-cadmium cell positive plate, its processing step is as follows:

(1) will be respectively based on the mass percent of slurry total amount: 40～50% hickelous nydroxide, 2～5% cobalt protoxide, 10～20% graphite evenly is stirred in together, adds 15～20% adhesive and 8～15% pure water then and evenly stirs at normal temperatures and be the positive plate slurry;

(2) use the slurry stove that slurry is coated in thickness to be: the nickel-plated steel of 0.2～1.0mm is online, and the bake out temperature of slurry stove is 100～140 ℃, and slurry speed is 80～100m/ hour;

(3) pole plate after employing nip drum machine will be dried rolls, and rolls the gap and is: 0.4～0.7mm, and hauling speed is 80～100m/ hour;

(4) adopt slitter, determine the positive plate of fixed dimension;

(5) on positive plate, weld positive pole ear.

The invention has the beneficial effects as follows: the present invention adopts nickel plated steel strip or steel mesh to make conducting matrix grain, carry out streamline production, improved production efficiency, improved the utilance of nickel, reduced cost, the production efficiency height, and technology is simple, thus the positive plate that can be widely used in ni-mh or nickel-cadmium cell is made.

Embodiment

1) will be respectively based on the mass percent of slurry total amount: 40～50% hickelous nydroxide, 2～5% cobalt protoxide, 10～20% graphite evenly is stirred in together, adds 15～20% adhesive and 8～15% pure water then and evenly stirs at normal temperatures and be the positive plate slurry;

2) use the slurry stove that slurry is coated in thickness to be: the nickel-plated steel of 0.2～1.0mm is online, and the bake out temperature of slurry stove is 100～140 ℃, and best bake out temperature is 120 ℃; Slurry speed is 80～100m/ hour, and best slurry speed is 90m/ hour;

3) pole plate after employing nip drum machine will be dried rolls, and rolls the gap and is: 0.4～0.7mm; The actual gap of rolling is as the criterion according to the actual product requirement;

4) adopt slitter, determine the positive plate of fixed dimension;

5) on positive plate, weld positive pole ear.
