Recycling of Utility-Scale Battery Storage Systems: Maximizing Efficiency and Sustainability


The disposal of lithium-ion batteries in large-scale energy storage systems is an emerging issue, as industry-wide guidelines still need to be established. These batteries, similar to those in electronic devices such as computers and cellphones, cannot be discarded as regular waste due to their components, like cobalt, nickel, manganese, and electrolyte chemicals, that can have an impact on the environment if not handled properly.


Proper disposal of these battery modules requires them to be treated as hazardous materials. The process is complicated and costly, involving trained professionals disassembling the modules, packaging and labeling them according to regulations, and transporting them to the disposal facility via rail, truck, or vessel. Careful safety protocols must also be in place to prevent thermal runaway risks.


Solar battery recycling involves several steps to dismantle, process, and dispose of the batteries properly. The first step is safely transporting the batteries from the decommissioning site to a recycling facility. The batteries are sorted by type and size at the facility, and any hazardous materials, such as acid or heavy metals, are safely removed. The remaining materials, such as lead, nickel, and cobalt, are then processed to extract these valuable materials, which can be reused in producing new batteries or other products.


How are batteries picked up?

​​Batteries are collected and transported in specially designed containers to ensure they are safely and properly handled. Batteries are handled with buffer materials, such as plastic, metal, or cardboard, that are designed to prevent the batteries from coming into contact with one another or shorting out. When batteries are collected from a decommissioning site, they are loaded onto a truck and transported to a recycling facility, where they can be appropriately processed, refurbished, or recycled. The batteries are typically sorted by type and size at the recycling facility, and any hazardous materials are safely removed. The remaining materials are then processed to extract valuable materials, such as lead, nickel, and cobalt, which can be reused in producing new batteries or other products.



How are Batteries Recycled?

  1. Collection: The first step in recycling is safely collecting the used lithium-ion batteries from the solar site. This typically involves transporting the batteries to a recycling facility in specially designed containers to prevent accidents or damage during transport.

  2. Sorting: Once the batteries arrive at the recycling facility, they are sorted by type and size. This helps ensure that the batteries are processed as efficiently and effectively as possible.

  3. Disassembly: The next step is to disassemble the batteries to safely remove hazardous materials, such as acid or heavy metals. This is typically done using specialized equipment and techniques to ensure that the materials are handled safely and responsibly.

  4. Material recovery: After the hazardous materials have been removed, the remaining materials, such as lead, nickel, and cobalt, are processed to extract these valuable materials. This is typically done using a combination of mechanical and chemical processes.

  5. Disposal: Any materials that cannot be recovered or reused are appropriately disposed of in an environmentally responsible manner. This may involve sending the materials to a landfill or incinerating them in a controlled setting.

  6. Reuse: The recovered materials are then made available for reuse in the production of new batteries or other products.

Overall, lithium-ion battery recycling aims to safely and responsibly dismantle and process the batteries to extract valuable materials and reduce the environmental impact of these batteries.


What is the cost of battery recycling?

Establishing costs for battery recycling varies depending on site factors. It’s important to get a quote for your special decommissioning circumstances. According to an Electric Power Research Institute study that explored cost details, these are some key findings:

  • The estimated cost to decommission a 1-MWh NMC lithium-ion battery-based grid energy storage system is $91,500.

  • The majority of costs are attributed to on-site dismantling and packaging (40%), transportation (30%), and recycling (30%).

  • The density of the battery significantly impacts total decommissioning costs due to the manual labor required for dismantling and packaging, as well as increased costs for transportation and recycling.

  • The costs for decommissioning modules can range from $50,000 to $150,000, depending on the energy density and battery chemistry.

  • US federal regulations only cover the transportation and proper labeling of lithium-ion batteries, while regulations vary at the state level.

  • Some states, such as New York, California, and Minnesota, have the most comprehensive regulations for recycling batteries, with manufacturers being responsible for collection and ensuring an accessible pathway for disposal and recycling.

  • Proper management of end-of-life tasks can lead to increased efficiency and reduced costs, depending on the capabilities of the parties involved.
