Electrifying our transportation system is crucial for mitigating emissions that trigger local weather change and opposed well being impacts. This electrification would require much more batteries and due to this fact much more minerals. Recovering these supplies from retired electrical car (EV) batteries is another supply to mining. Primarily, the supplies recovered by means of battery recycling can substitute future materials provide that will in any other case should be extracted from the earth to fulfill demand.
Estimates present that in 2050, the USA can meet about half of EV demand for cobalt and nickel and 1 / 4 of lithium with minerals recovered by means of recycling. Whereas EVs already lead to much less greenhouse fuel emissions than the gasoline various, utilizing these recycled supplies considerably lowers impacts related to materials sourcing.
Previous to recycling, the battery retired from use in an EV can be utilized in a second-life utility. This implies it’s both reused in one other car or it’s repurposed to be used in a stationary storage utility. Ultimately, the battery will attain its finish of life and ought to be recycled, recovering minerals to then return into the battery manufacturing stream.
The round course of begins at manufacturing, flows to the primary use in an EV, is repurposed for a second life, recycled, after which ultimately the minerals are again to manufacturing. That is known as materials circularity or the round economic system.
Battery coverage agreed upon within the European Union implements round economic system ideas and is probably the most bold battery coverage thus far. It has the potential to extend the recycling of batteries and the usage of recovered supplies by means of prolonged producer duty and recycling necessities. Within the US, California can be exploring recycling and materials circularity coverage. In 2022, a report was launched by the California Electrical Car Battery Recycling Advisory Group which outlines insurance policies the group believes the California legislature ought to implement.
Insurance policies mentioned and proposed by these teams have the potential to extend the reuse, repurposing, and recycling of batteries, in addition to mitigate impacts related to end-of-life processes and enhance battery sustainability. As insurance policies develop, we on the Union of Involved Scientists have outlined the next high-level ideas that we are going to use to information our coverage positions.

Let’s dive into these ideas a bit additional.
Elevated battery recycling & materials circularity is important for a sustainable battery business.
Recycling EVs already on the highway is probably the most sustainable option to supply supplies. Embedded in these batteries is a extremely concentrated quantity of minerals that may be recovered by means of recycling. Newer recycling processes report restoration charges of 95% and low air pollution impacts. It is a considerably higher various than incineration-based strategies which don’t at the moment get better any of the lithium and do emit greenhouse gases and particulate matter.
As soon as recovered, these minerals can be utilized to fabricate new batteries, due to this fact lowering the necessity for brand new mining. General, the decreased mining could make EVs extra sustainable and reduce the chance of mishandling by means of insufficient storage or landfilling.
The producer (usually, the car producer) ought to be answerable for guaranteeing EV batteries are reused, repurposed, and ultimately recycled.
Presently, the USA doesn’t require EV battery recycling. Whereas recycling is going on, there’s the potential for market dynamics to not catch all retiring batteries, due to this fact resulting in improper disposal. Some newer batteries aren’t utilizing cobalt and nickel, that are historically the very best worth minerals in EVs. This pattern is helpful as a result of it ends in decrease price and extra environmentally pleasant EVs. However on the flip aspect, the recycling of batteries with out these minerals isn’t at the moment worthwhile.and due to this fact will not be recycled if there isn’t regulation requiring it.
One potential coverage answer is to outline a central celebration accountable, resembling producers, for guaranteeing batteries are recycled. Defining duty can enhance the recycling charge and incentivize planning and effectivity.
The automotive producers are greatest suited to this place, following the standard coverage construction referred to as Prolonged Producer Duty (EPR). By centralizing duty to the automotive producer, it not solely ensures the battery is recycled, but in addition incentivizes the producer to design the battery and EV in a manner that makes recycling simpler and cheaper.
This has been applied for EV batteries within the European Union and was proposed by the California Advisory Group (the report makes use of the time period ‘producer take-back’). A sort of prolonged producer duty is used for guaranteeing the recycling of a number of merchandise in California, together with mattresses, paint, and carpet.
The battery recycling course of ought to lead to low environmental impacts and have a excessive charge of fabric restoration, particularly for lithium, nickel, and cobalt.
Mineral restoration by means of recycling outdated batteries is considerably cleaner than mining new supplies, and it’s important that insurance policies maximize the environmental advantages of recycling. This may be carried out by means of required materials restoration charges and environmental influence reporting. Applied sciences are advancing and a number of other new recycling firms state a 95% materials restoration charge. This greatest accessible know-how ought to be used, and the usage of incineration-based strategies that don’t get better lithium shouldn’t be allowed.
Previous to recycling, the battery ought to ideally be reused, refurbished and/or repurposed, whether it is protected and has remaining capability.
Ultimately, all batteries ought to be recycled. However prior, many batteries can be utilized within the environmentally advantageous second-life utility resembling reuse, refurbishing, and repurposing. Reuse and refurbishing check with reusing batteries in the identical utility, however in a special automotive. Repurposing refers to utilizing the battery in a special utility, resembling for stationary storage to help renewable vitality technology. Learn this wonderful weblog if you need to study extra.
The battery end-of-life ought to be thought of throughout the design of the EV and the battery.
When an EV is retired, the battery is faraway from the car after which sometimes additional disassembled. If the disassembly is deliberate for throughout the design of the EV and the battery, the method can turn out to be safer and extra environment friendly. Examples of potential deconstruction course of enhancements by means of EV and battery design contains the usage of binders as a substitute of adhesives and standardization amongst pack design. Disassembly is at the moment a guide course of, but when batteries are standardized and constructed to be taken aside, sensible robots may as a substitute do that job.
If prolonged producer duty is established, design for disassembly and recycling is of course incentivized.
Details about the battery’s well being over time ought to be accessible when the battery is within the car and after its removing.
The battery well being refers back to the capability and effectivity of the battery, one thing that slowly degrades over time and with use. This indicator is usually represented as a share and communicates the battery’s p.c most accessible capability compared to when the battery was new. It is vital for EV homeowners to know the well being of their battery, an indicator that’s required beginning in 2026 for EVs in California.
It is usually necessary for battery well being to be accessible as soon as the battery is faraway from the automotive. The battery well being is a key determinant in deciding if the battery ought to be reused, repurposed, or despatched on to recycling. If the battery is in good well being (i.e. comparatively excessive capability and effectivity), it ought to be reused or repurposed for a second-life previous to recycling.
Presently, if there is no such thing as a visible injury, battery repurposers take a look at the well being by monitoring it by means of a whole cost and discharge or a specifically designed testing course of. That is costly and time-consuming, but when this data was offered with out intensive testing, repurposing may be expedited, and prices decreased.
Authorities funding ought to proceed to help analysis and improvement of repurposing, reuse, and recycling.
As we transition away from the gasoline car to the extra environmentally pleasant EV, battery recycling and materials circularity ought to be precedence. As mentioned in a previous weblog, there have been funds devoted in the direction of recycling analysis, improvement, and demonstration. Whereas this funding is crucial to growing a extra sustainable battery business, we additionally want coverage that requires and ensures a round battery economic system.
What’s subsequent for battery recycling coverage
At UCS, we wish to see that each one EV batteries are safely recycled and the supplies recovered are used within the manufacturing of subsequent technology batteries. These supplies are an important a part of assembly upcoming demand and lowering the necessity for mining.
US coverage ought to comply with the instance of the European Union by implementing prolonged producer duty, requiring excessive materials restoration charges, and rising entry to battery data. Keep tuned for extra blogs that dive into these ideas.
