Benedikt Sobotka warns that the dearth of recycling functionality may dramatically restrict the pace at which the EV transition takes place
Transportation presently accounts for 37% of world CO2 emissions, in keeping with the Worldwide Power Company, which implies the decarbonisation of the transport sector varieties an important a part of any severe plan to handle local weather change. On the coronary heart of this course of is the transition from conventional, inner combustion engine (ICE) automobiles to electrical automobiles (EVs).
World electrical automobile gross sales have continued on a powerful upward pattern in 2022, with 2 million offered within the first quarter—a 75% enhance from the identical interval in 2021. Nevertheless, to maintain assembly this quickly rising demand, better consideration have to be positioned on the reuse, repurposing and recycling of the batteries that energy EVs.
Present EV battery recycling market
At current, solely round 5% of lithium-ion (Li-ion) batteries are recycled globally, which is a regarding state of affairs, notably when Greenpeace predicts that over 12 million metric tonnes of Li-ion batteries are anticipated to retire by 2030. Not solely is that this an infinite quantity of waste, however the lack of recycling functionality may dramatically restrict the pace at which the EV transition takes place.
This downside has been recognised and is, to a sure extent, being addressed, with a current spate of investments in recycling infrastructure and know-how. For instance, within the UK, firms alongside the availability chain akin to Veolia, BritishVolt and European Metallic Recycling have all introduced main recycling initiatives in 2022, which can collectively course of tens of hundreds of tonnes of batteries yearly. The affect of this may very well be important for the UK; with the assistance of initiatives like these, the WMG crew on the College of Warwick predicts that recycling may provide 22% of the nation’s required battery materials by 2040.
Continental Europe can also be seeing development within the recycling sector. Simply take a look at Volkswagen, which lately introduced a battery recycling pilot in Germany that would recycle as much as 97% of the elements of a battery, or Renault, which is seeking to repurpose EV batteries as power storage in France.
12 million metric tonnes of Li-ion batteries are anticipated to retire by 2030
Nevertheless, the recycling of Li-ion batteries nonetheless lags behind the quickly creating EV manufacturing business, each by way of funding and know-how. There are numerous causes for this, together with the financial viability of recycling batteries, the technological complexity of reprocessing diverse and quick evolving battery varieties, and logistical friction factors because of regulatory points.
Environmental case for EV battery recycling
At present, one of many main points with EV batteries is their contribution to environmental degradation in landfills and areas the place they’re disposed. A few of the key elements of batteries, akin to copper, nickel and lead, could be extremely poisonous. Because the batteries decay, these chemical compounds can leak into the encompassing space, inflicting hurt to the native ecosystems.
Lead acid batteries current a threat, with one in three youngsters globally uncovered to guide poisoning because of insufficient lead-acid battery recycling, in keeping with a report by UNICEF and Pure Earth. The long-term hurt this could trigger if not tackled is staggering. It’s estimated that lead poisoning is liable for a discount of round 2% of GDP in Asia and 4% in Africa because of the affect on productiveness in some communities. Bettering the battery recycling price to battery disposal price ratio can cut back the dangerous affect of EVs on the setting—and on people.
Recycling also can contribute extra broadly to the battle towards local weather change by means of the availability of commodities wanted to assist the power transition. These supplies additionally play a major position in facilitating the implementation of renewable power technology strategies. For instance, photo voltaic and offshore wind must and 5 occasions as a lot copper respectively than conventional power technology strategies.
Historic underinvestment in mining initiatives, coupled with the lengthy lead occasions for his or her improvement, implies that the availability of metals like cobalt and copper will battle to maintain up with the demand pushed by the elevated use of renewables. Recycling the used steel from batteries can assist the manufacture of a variety of fresh power applied sciences and speed up motion towards international warming.
Financial arguments for recycling batteries
Whereas the environmental benefits of recycling are clear, in a world the place firms and governments usually prioritise returns and profitability, it is very important additionally replicate on the financial advantages of accelerating the recycling price of EV batteries. First off, supporting the availability of key minerals will mood steel costs which in any other case may surge uncontrollably. In flip, this controls the value of EVs on the level of sale, making them extra accessible to the buyer and accelerating their uptake and the shift in the direction of clear transport.
Nevertheless, the financial advantages are a lot wider than this. At present, recycling infrastructure and the recycling business is in want of great improvement and additional funding. The enlargement of the business provide chains will create new jobs, enhance financial exercise and spur development. In truth, the worldwide lithium-ion battery market is projected to develop from US$4.6bn in 2021 to US$22.8bn by 2030, in keeping with Markets and Markets. And whereas within the quick time period, the markets for repurposing and recycling could compete for finish of life battery volumes, in the long run, there isn’t a doubt: the markets are complementary. Repurposed batteries will finally require recycling.
This development in itself can present a much-needed enhance, particularly to areas akin to some African nations, the place the battery recycling business is extraordinarily underdeveloped. However past that, whereas these nations will profit from job creation, expertise diversification and elevated financial exercise, the repurposing of batteries can enhance their economies way more instantly. Repurposed batteries can allow elevated power entry the place there’s a giant hole between these with entry to electrical energy, and people with out it.
Can a ‘Battery Passport’ assist?
Battery recycling will clearly be a pressure for good. Nevertheless, there stay obstacles to the business’s improvement which have to be overcome whether it is to achieve its full potential. Differing rules implies that there are sometimes friction factors which forestall or stall the transboundary motion of lithium-ion batteries for recycling and repurposing. Moreover, as batteries evolve to develop into extra environment friendly, longer lasting and safer, they develop into extra advanced—as does recycling them.
An answer could be present in offering extra transparency and data on the battery cycle and its interval of utilisation within the EV. Making this data accessible to related stakeholders, governments and firms can make sure that any explicit battery is appropriate for recycling, conforms to related requirements, and has the mandatory elements to make recycling or reuse doable.
The World Battery Alliance (GBA), the biggest multi-stakeholder organisation of its sort, includes round 110 nationwide governments, business actors, and NGOs—together with WEF, UNICEF, Eurasian Sources Group, BMW and Tesla—and is working to resolve a few of these points.

The GBA is creating a ‘Battery Passport’, which can give each battery an identification, performing as a digital twin of the battery to file necessary data throughout its whole lifecycle. It can present end-users with key knowledge about its materials provenance, chemical make-up, manufacturing historical past, in addition to relevant ESG and lifecycle necessities, primarily based on the great definition of a sustainable battery. This technical knowledge will likely be collected from worth chain stakeholders together with mining firms, refiners, cell producers, module producers, battery producers, automotive OEMs and recyclers.
By setting related efficiency indicators, and monitoring and validating battery efficiency towards these indicators, the GBA’s Battery Passport will subsequently create better transparency throughout the worth chain and facilitate useful resource effectivity, life extension, protected second use and stronger battery recycling.
Extra extensively, the Battery Passport is a first-rate exemplar of an engine-room initiative that may have severe governance affect that reaches all ranges of society. From serving to safeguard these on the coalface of manufacturing, to making sure the standard of a battery hundreds of kilometres away to a shopper, the Battery Passport has the potential to the touch each side of how we have interaction with the 21st century’s breakthrough electrical applied sciences.
