Spent lithium-ion batteries have stopped being a niche problem. Electric vehicles, consumer electronics, and stationary energy storage all dispose of batteries on an industrial scale, and every one of those cells still holds valuable lithium, nickel, cobalt, copper, and graphite. That is why lithium battery recycling has grown from a disposal service into a strategic part of the global materials supply chain. If you are setting up or expanding a recycling line, the first question most buyers ask is simple: which companies in the world are actually doing this at scale? This article answers that question and then explains what separates a name on a list from a supplier you can build a plant around.
The companies leading lithium battery recycling today
A handful of companies dominate the conversation because they combine operating scale, recovery technology, and access to returned batteries. Most of the largest players sit in Asia, where battery manufacturing is concentrated, but strong recyclers also operate in Europe and North America. Among the most frequently named are:
- Brunp Recycling (China), affiliated with battery maker CATL. It runs one of the broadest closed-loop models, covering battery making, battery use, echelon utilization, and recycling, with a large installed traction-battery recycling capacity and more under construction.
- Zhejiang Huayou Cobalt (China). Built a closed-loop lithium battery materials chain spanning collection, dismantling, cascade use, hydrometallurgical processing, and resource regeneration.
- GEM Co., Ltd. (China). One of the country's major circular economy and power battery recyclers, reporting multiple power-battery recycling plants and large annual dismantling and black-mass recycling capacity.
- Umicore (Belgium). A long-established European materials technology firm whose battery recycling solutions treat and recover metals from lithium-ion batteries at industrial scale.
- Ganfeng Lithium (China). An integrated lithium enterprise covering resources, compounds, battery manufacturing, and recycling of retired batteries.
- Redwood Materials (United States). Focused on recovering critical materials from end-of-life batteries and production scrap and returning them to the domestic supply chain, claiming recovery of more than 95% of critical materials.
- Ecobat (global). Expanded from traditional battery recycling into lithium-ion recycling, now running plants in the United States and Europe.
- Fortum Battery Recycling (Finland) and Cirba Solutions (United States). Important regional players, with Fortum running a large hydrometallurgical facility in Finland and Cirba expanding black-mass production in North America.
What these recyclers have in common
Look past the brand names and the leaders share four things. First, they operate at genuine industrial scale, processing tens of thousands of tonnes of cells a year rather than small pilot batches. Second, their recovery rates are high, typically returning the bulk of the lithium, nickel, cobalt, and copper in each battery back into new products. Third, they run compliant operations with proper environmental controls, because battery material can be toxic and flammable if handled carelessly. And fourth, they close the loop, feeding recovered material back to battery or chemical manufacturers rather than selling it off as generic scrap. Any recycler you evaluate should be able to demonstrate all four of these, not just one.
Why big recyclers and equipment suppliers are not the same thing
A common misunderstanding is that the companies listed above build the machinery everyone else buys. In reality, most of them are recyclers: they own and operate plants. If your goal is to build your own lithium battery recycling operation, you need a different partner, one that designs, manufactures, and commissions the actual equipment. That is where a machinery specialist like San Lan Technologies comes in.
How a lithium battery recycling line turns cells into value
Regardless of who runs the plant, the process follows the same steps. Spent batteries are first discharged to make them safe to handle, then pre-crushed and shredded. The crushed material is separated by size, and magnetic separation pulls out iron and steel components. What remains goes through further granulation and classification to recover black mass, which contains the nickel, cobalt, and graphite, as well as separate streams of copper and aluminum and the plastic separator film. Each fraction becomes a saleable product. A complete lithium battery recycling plant such as San Lan's is designed to run this whole sequence of discharging, pre-crushing, secondary granulation, black powder separation, and magnetic separation of iron and steel in capacities from 500 to 2,500 kg per hour.
The support systems that make recycling safe
A profitable recycling plant is more than a crusher and a separator. Battery material generates dust and, during any thermal step, harmful gases that must not reach the atmosphere. Operators therefore pair the recycling line with an air pollution control system for the li battery recycling plant that absorbs and neutralizes these gases before release. The lightweight plastic separator film recovered during crushing is collected by a pneumatic conveying system and pressed into compact blocks by a hydraulic briquetter, which cuts handling costs and recovers a clean, baleable product.
How to choose the right partner for your project
Whether you plan to compete with the global leaders or simply build a regional recycling business, the equipment decision is what determines whether the project works. Ask any supplier these questions before you commit:
- Can they show a working plant at the capacity you need, not just a brochure?
- Do they handle the whole line, from discharging and crushing to separation and emission control, so you buy one integrated system instead of mismatched parts?
- Do they offer installation, commissioning, operator training, and spare parts after the sale?
- Can they customize the plant to your feed material and target output?
The bottom line
The world's major lithium battery recyclers share industrial scale, high recovery rates, strict compliance, and closed-loop material channels, and these are exactly the qualities to look for whether you are buying recycled material or building your own plant. When your project needs the machinery rather than the brand, the practical path is to work with an equipment specialist that can supply the complete line and support it for years. San Lan Technologies has spent more than a decade and a half manufacturing recycling equipment for e-waste, lead acid batteries, and lithium batteries, and offers one-stop EPC support from plant design through installation and commissioning to help you turn spent cells into a working business.
