Equipment of Lithium Battery Recycling

As countries around the world implement mandatory policies for lithium-ion battery recycling, the circular economy for these batteries has emerged as a definitive, trillion-scale market sector. SUNYGROUP remains committed to the continuous iteration and upgrading of its core processes—including pyrolysis-carbonization, low-temperature shredding, and ultrafine sorting—while further enhancing the automation, energy efficiency, and environmental compliance of its integrated equipment.

SUNYGROUP’s lithium-ion battery recycling industrial solution comprises three primary core stages:

Front-end Shredding and Pre-treatment: Equipped with large-scale sealed feeding hoists and integrated shredding units, along with elevated operating platforms, this stage allows for the direct input of end-of-life power batteries without the need for extensive manual dismantling. The entire process operates under a sealed, negative-pressure environment, preventing the escape of dust or odors from electrolytes. This system is highly versatile, capable of processing a wide variety of feedstocks, including dismantled battery modules, pouch cells, and retired energy storage batteries.

Core Pyrolysis-Carbonization Stage: The heart of the production line is a patented horizontal continuous pyrolysis-carbonization furnace. Utilizing an indirect-heating, oxygen-free pyrolysis process, it breaks down organic separators and electrolytes at low temperatures. This enables the efficient separation of aluminum-laminate films, copper/aluminum foils, and graphite-rich “black mass.” A multi-stage oil-gas condensation and recovery system allows for the resource recovery of electrolyte-derived vapors, ensuring the simultaneous capture of solid, liquid, and gaseous components. The furnace is paired with an independent, intelligent temperature-control cabinet, ensuring precise thermal regulation and significantly increasing the purity of the recovered black mass.

Back-end Ultrafine Pulverization and Exhaust Gas Purification: Following pyrolysis, the battery materials are fed into a sealed ultrafine pulverization and dissociation system, which facilitates the efficient separation of copper, aluminum, and graphite. The system concludes with a comprehensive, eco-friendly exhaust gas treatment unit; through multi-stage scrubbing and adsorption, exhaust gases are purified to meet regulatory standards. This ensures full compliance with local environmental emission regulations in India, enabling “green” production with no environmental risks.

The entire lithium-ion battery recycling line features a modular steel-structure layout and an integrated, intelligent electrical control system. Each production line supports 24-hour continuous, automated operation, minimizing the need for manual intervention—an ideal configuration for the low-cost, efficient maintenance and operation requirements of overseas facilities. Catering to the global market, SUNYGROUP offers customized, end-to-end lithium-ion battery recycling solutions. Our portfolio ranges from small-scale pilot lines and medium-capacity production lines to large-scale, continuous pyrolysis-based industrial plant solutions. We tailor our offerings to meet the specific environmental standards, facility constraints, and feedstock types of different countries, providing a comprehensive, one-stop service that encompasses process planning, equipment manufacturing, export delivery, and ongoing technical support abroad.
