Abstract

The invention provides a resource recycling production method of waste nickel cadmium batteries, relating to a physical separation method for the various components of the waste nickel cadmium battery, including a shell, an electrolyte, a positive plate, a negative electrode material and a negative electrode electricity collecting body perforated steel ribbon, and a recycling scheme of a pure electrode material obtained by separation; and the method provides a low-cost way for resource recycling production of the waste nickel cadmium battery. Concretely, all the components of the waste nickelcadmium battery are separated by the physical method at first, then the obtained positive plate and negative electrode powder are chemically treated to prepare new positive electrode material Ni(OH)2and negative electrode material Cd(OH)2 of the nickel cadmium battery, and then the commercialized nickel cadmium battery production line is used for producing new nickel cadmium batteries.

Description

A kind of recycling production method of waste nickel-cadmium battery technical field The present invention relates to a physical separation method for various components of waste nickel-cadmium batteries, including shell, electrolyte, positive electrode material, negative electrode material, current collector perforated steel strip, and the separated positive electrode material and negative electrode material. The reuse scheme provides a low-cost route for the recycling of waste nickel-cadmium batteries and the recycling production of nickel-cadmium batteries. Background technique Nickel-cadmium (Ni-Cd) battery, also known as nickel-cadmium battery, is a fairly mature secondary battery. It has the characteristics of long service life, high output power, and short charging time, and is currently mainly used in the power tool industry. Driven by strong market demand, my country has become the world's largest producer of nickel-cadmium batteries, with an annual output of 1 ...
