    A method is disclosed for the manufacture of a highly porous nickel electrode body for electrical accumulators. The new electrode body is also disclosed. By using 5-7% by volume of a nickel powder in admixture with 93-95% by volume of a pore-forming agent selected from the group consisting of ammonium bicarbonate and ammonium carbonate when pressing and sintering the electrode body a very high porosity is obtained, such as 90-95%, in spite of which the mechanical strength of the body is so high as to resist the strains of an accumulator cell. Especially preferable to impart outstanding strength to the electrode body, is a pressure of at least 100 MPa in the pressing operation.

    1 The invention relates to electrical engineering industry and can be used in the production of bezlamelny electrodes of electric batteries. The known method of manufacturing the electrode base battery of an electric battery by mixing carbonyl nickel powder with plastic powder in a reducing atmosphere at 90-tOO C for 10 minutes followed by the introduction of 40-50% of a pore-forming agent, for example ammonium bicarbonate, pressing the resulting mixture onto the lead and heating in a reducing environment to 200–220 0 and delivery at this temperature for 10 min. lJ. However, the known method is complicated and inefficient. The closest in technical essence and achievable results to the proposed method is the manufacture of a porous base of an electric battery type by pressing a mixture of nickel powders and a bicarbonate and / or {carbonate of ammonium carbonate at a pressure of 30140 MPa on a conducting basis, followed by sintering at 865% . The blowing agent is introduced in the amount of 38%, nickel powder - 62%. To obtain good electrical characteristics of the electrode, it is latent to have the largest possible percentage of pores in the base, since the pores are designed to accommodate the active material and electrolyte access. However, the mechanical strength of the base is reduced, all the more so as the volume of the active material changes in the pores of the base during the charge cycle cycles. . The chain of the invention is an increase in strength. This goal is achieved by the fact that according to the method of manufacturing the porous base of the electric battery electrode by pressing on the conducting osng mixture of nickel powders and a bicarbonate and / or carbonate ammonium powder with a pressure of 30-140 MPa, followed by sintering at 865%, the porogen is introduced into 93-95% by volume, and nickel powder 5-7% by volume, and the size of the pore-forming agent of the developer is chosen to be more than 0.3 mm, mainly 0.33 mm. Example 1. Nickel powder with a particle size of 2.6-3.4 µm in an amount of 7% by volume is mixed with ammonium carbonate having a particle size of 0.33 m, then pressed at a pressure of 30 MPa onto a conductive base and sintering is performed in a reducing atmosphere for 45 min. The resulting porosity is 90.4%, shrinkage in width is 21%, fracture resistance is 0.96 MPa. Example 2 is carried out according to Example 1. A compaction pressure is 70 MPa. The base porosity is 89.8%, width shrinkage is 18%, fracture resistance is 1.53 MPa. Example 3 is similar to example 1, the pressing pressure is 140 MPa. The base porosity is 89.6%, width shrinkage is 17%, fracture resistance is 2.50 MPa. Example 4 of the process is similar to example 1, but the amount of nickel powder is 6% by volume, the blowing agent is 94% by volume. The base porosity is 91.2%, width shrinkage is 23%, fracture resistance is 0.61 MPa. Example 5 is the same as Example 4. The pressing pressure is 70 MPa. Porosity is 90.6%, width shrinkage is 19%, fracture resistance is 1 MPa Example 6 is the same as Example 5. The pressing pressure is 140 MPa. The base porosity is 90.8%, width shrinkage is 16%, fracture resistance is 2.47 MPa. Example 7 of the method is the same as Example 1, but the amount of nickel powder is 5% by volume, the blowing agent is 95% by volume. Base porosity 93%, width shrinkage 16%, fracture resistance 0.20 MPa. Example 8 is similar to Example 7. The pressing pressure is 70 MPa, the base porosity is 92.7%, the width shrinkage is 16%, the fracture resistance is 0.37 MPa. Example 9 is similar to example 7. Pressing pressure is 140 MPa. Base porosity 92.7%, width shrinkage 16%, fracture resistance 0.69 MPa.
