Problems solved by technology
[0002] Ordinary nickel foam materials such as spongy nickel foam materials, as porous metal nickel mesh plates, can be used as current collectors for positive and negative plates of batteries and carriers of active materials; when making high-energy battery electrode plates, these pores can be used to make electrodes The active material of the plate is fully utilized and the internal resistance of the battery is reduced. It is difficult to improve the capacity, charge and discharge capacity, and discharge current of the battery. It is difficult to adapt to the development needs of the current power battery.

Embodiment Construction
[0032] Below in conjunction with accompanying drawing, technical solution of the present invention is described in further detail:
[0033] The preparation method of alloy nickel foam is prepared by the following production process:
[0034] 1. Including conductive treatment of mold core - electrodeposition - heat treatment under the protection of hydrogen atmosphere; see Figure 1.
[0035] 2. The conductive treatment of the mold core is dip-coating conductive glue, which is a colloidal solution formed by dispersing high-purity ultra-fine graphite in pure water. Its solid content is greater than 9%, and the diameter of the graphite body is less than 1 micron, which is stable Ammonia NH 3 ·H 2 O; The conductive medium can be graphite, carbon black, or acetylene black.
[0036] The conductive treatment process of the mold core is: sponge, prepreg, dipping, film removal, uniform pressing, drying, curing, and conductive sponge. The whole process is a mechanized flow operatio...

Abstract
This invention relates to preparation of foamed Ni alloy to solve some problem at present process. It is carried out by: conductive treatment of mould core ->electrodeposition->heat treatment under the protection of hydrogen. Foamed nickel with fine performance and homogeneous alloys was produced by the method, so that high current generating capacity of battery and over-charging resistance and discharge capacity. The nickel foam was one of the ideal materials as powerful batteries, specially for high-current nickel-hydrogen batteriesand lithium ion batteries.
Description
Technical field [0001] The invention relates to a preparation method of alloy nickel foam, in particular to a preparation method of a novel nickel foam whose composition is different from common nickel foam. Background technique [0002] Ordinary nickel foam materials such as spongy nickel foam materials, as porous metal nickel mesh plates, can be used as current collectors for positive and negative plates of batteries and carriers of active materials; when making high-energy battery electrode plates, these pores can be used to make electrodes The active material of the plate is fully utilized to reduce the internal resistance of the battery, which is difficult to improve the capacity, charge and discharge capacity, and discharge current of the battery, and it is difficult to adapt to the development needs of the current power battery. Contents of the invention [0003] The purpose of the present invention is to provide a kind of alloy nickel foam containing multiple eleme...
