The recycling of spent/discarded lead-acid batteries was highly regarded by the state for a long time, and the recycling technology and equipment have been also improved and upgraded constantly. The paper briefly introduced the technical status of the recycled lead industry, including crushing and separation of waste lead-acid batteries and recovery of waste lead paste resources, described the evolution process of mechanical, automatic and intelligent crushing and sorting of waste lead-acid batteries, and focused on the progress of high temperature smelting, pre-desulfurization and low temperature smelting, smelting-free conversion and other technologies in the recovery of waste lead paste resources. The systematic layout and modular implementation of waste lead-acid battery resource recovery technology and equipment is the fundamental guarantee for the progress of industrial technology and equipment, and intelligent and green conversion is the future development trend, and the technology of intelligent crushing and separation of spent lead-acid batteries and short-flow preparation of lead-based power supply materials from waste lead paste without melting is expected to lead the development of the industry and promote the realization of the carbon peaking and carbon neutrality goals.
