いる。Conventional hydrogen storage electrodes for lithium batteries are manufactured by immediately adding hydrogen storage alloy powder and a binder to a viscous agent solution, kneading the prepared paste, filling it onto a porous metal substrate, and then drying and baking it. There is a formula that In this case, in order to improve conductivity, one powder is added during kneading.

る（特開昭６１−６４０６９号）。In order to activate the hydrogen storage alloy powder, improve its hydrogen storage and release properties, improve its chemical stability against electrolytes, and prevent alloy particles from collapsing and falling off, the hydrogen storage alloy powder is subjected to electroless plating. A micro-encapsulated hydrogen storage alloy coated with plating was prepared in advance, and a binder and a viscosity agent liquid were added to the slurry, which was prepared by kneading, and then filled and applied onto a porous metal substrate to form a hydrogen storage electrode. It has also been proposed to produce (Japanese Patent Application Laid-Open No. 61-64069).

When using TFE, regardless of whether or not it has a plating coating on its surface, the PTFB fiberized by kneading during slurry preparation will be entwined with the surface of the alloy powder particles and interposed between the alloy powder particles. inhibits conductivity. During the kneading, N
Even if i powder is added and mixed to make it conductive, there are disadvantages such as it is difficult to uniformly improve the conductivity as it is uniformly dispersed throughout the entire plate as a <-1 polar plate.

する。The present invention solves the above-mentioned conventional disadvantages, and provides a method for manufacturing a hydrogen storage electrode that reliably improves uniform conductivity and has increased discharge characteristics. The mixture is subjected to electroless plating immediately or after pulverization, and a viscous agent liquid is added to the resulting plating mixture and kneaded to prepare a paste. It is characterized by filling and coating on a metal substrate.

生じ易い。By mixing the hydrogen storage alloy powder and the binder powder, a mixture is obtained in which the binder powder is uniformly adhered to the alloy particles in the mass of the hydrogen storage alloy powder. In this case, when a fibrous binder powder is used, it becomes fibrous due to the mixing action and becomes entangled with the alloy particles, and is likely to cause numerous voids between the fibers as a whole.

の充填量は増大し容量の増大をもたらす。When the mixture is immersed in an electroless plating bath and subjected to electroless plating treatment, plating will precipitate on the surface of the alloy particles that are not covered with the binder. can be formed so large that it partially covers the surface of the alloy particles or even covers the surface of the binder interposed between the alloy particles. When a fibrous binder is used, in particular, numerous voids are created between the fibers, through which the plating bath can easily flow, resulting in uniform plating throughout the mixture. In addition, when the above-mentioned mixture is pulverized, the mass of the mixture of binder fibers and alloy powder is pulverized to obtain a pulverized product in which short fibers and fine alloy powder are uniformly mixed. When such a pulverized mixture is plated, a more dense plating coating can be obtained. When preparing a paste by kneading the plating mixture thus obtained with a viscosity agent liquid, the plating covering the binder is uniformly and finely dispersed throughout the paste. Since the paste is then filled into the porous metal substrate, a positive electrode with improved conductivity and, therefore, good discharge characteristics can be obtained. In this case, since the fibers of the binder are pulverized by the pulverization treatment as described above, the amount of the paste filled into the substrate increases, resulting in an increase in capacity.

。A desired one is selected from various conventionally known hydrogen storage alloy powders, such as LaN! <,y Al. , j is used as a raw material, an appropriate amount of a binder powder, preferably a fibrous binder powder, such as PTFE, is added thereto, and the mixture is thoroughly stirred using a stirrer or the like to form a uniform mixture. obtain. As a result of this stirring, most of the binder powder is turned into fibers, which are uniformly mixed throughout the alloy powder mass, and which are partially entwined with the surfaces of the alloy particles, but have countless voids between the fibers. A ribolus mixture is obtained. The porous mixture is immediately plated or ground. Preferably, the mixture is pulverized by a pulverizer (mill) to prepare a pulverized mixture in which the several aggregates are pulverized into finer fibers and the alloy powder particles are further refined. The unpulverized mixture or the pulverized mixture thus obtained is subjected to any known electroless plating treatment.

ある。For example, an example will be described in which plating is performed using copper, which has the highest conductivity. Of course, in addition to copper, plating with nickel or other suitable metal with good conductivity may be performed.

理混合物が得られる。First, for example, the above-mentioned pulverized mixture is placed in a porous container such as a basket, and immersed in the MAC-100 for briding treatment, and then immersed in MAC-200 to remove the alloy in the mixture. An active film that promotes the deposition of electroless copper plating is formed on the surface of each particle of the powder mass, and then this is immersed in a plating solution bath of MAC-500 to precipitate copper plating on the surface of the alloy powder. Not only that, but the resulting plating is allowed to grow, and the surface of the binder that partially covers the surface of the alloy particles is plated, as if it were plated. The processing liquid at each stage of the plating process flows and diffuses into the mixture through the numerous gaps between the fibers. Therefore, the resulting steel plating is a plating mixture in which plating is uniformly mixed throughout.

For example, when filling and coating a foamed metal substrate, filling a paste using a pulverized mixture can be done more easily and quickly than using a paste using an unpulverized mixture, and the amount of filling can be reduced. It was also observed that there was an increase in

A conventional positive electrode plate (hereinafter referred to as B electrode plate) was manufactured in this manner. Furthermore, the same hydrogen-absorbing alloy powder was prepared in advance with copper plating using the same method, and the plating-coated hydrogen-absorbing alloy and the same viscous agent liquid as the PTFE binder were mixed in the same proportions and thoroughly kneaded. A prepared paste in which PTFE had been sufficiently fiberized was filled and applied onto the same porous substrate, dried and fired in the same manner to produce a microencapsulated hydrogen storage alloy type positive electrode plate (hereinafter referred to as C electrode plate). .
