Core technologies for dry recycling of lithium batteries
By employing special discharge treatment, dry crushing, physical sorting, and black powder recovery technologies, we redefine the resource recycling efficiency of waste lithium batteries.
What is dry recycling?
Low energy consumption and low emissions
High-value resource recycling
The equipment is stable and reliable.
Dry recycling is a lithium battery recycling method that focuses on physical treatment, special discharge, crushing, and sorting. Compared to traditional wet recycling, which relies on acid and alkali chemicals, solid-liquid separation, crystallization precipitation, and wastewater treatment, dry recycling reduces the burden of chemical treatment and wastewater management, simplifies the process, and is suitable for large-scale industrial applications.
The dry technology for lithium generation can be applied to the pretreatment of waste lithium batteries, black powder recycling, metal resource separation and subsequent purification processes.
