Benedikt Sobotka warns that the shortage of recycling functionality might dramatically restrict the velocity at which the EV transition takes place
Transportation at the moment accounts for 37% of worldwide CO2 emissions, in keeping with the Worldwide Power Company, which implies the decarbonisation of the transport sector kinds a vital a part of any severe plan to deal with local weather change. On the coronary heart of this course of is the transition from conventional, inside combustion engine (ICE) autos to electrical autos (EVs).
World electrical automobile gross sales have continued on a powerful upward pattern in 2022, with 2 million bought within the first quarter—a 75% improve from the identical interval in 2021. Nevertheless, to maintain assembly this quickly rising demand, higher consideration should 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 might dramatically restrict the velocity 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 expertise. For instance, within the UK, corporations alongside the availability chain corresponding to Veolia, BritishVolt and European Steel Recycling have all introduced main recycling initiatives in 2022, which is able to collectively course of tens of 1000’s of tonnes of batteries yearly. The influence of this might be important for the UK; with the assistance of initiatives like these, the WMG group on the College of Warwick predicts that recycling might 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 parts of a battery, or Renault, which is trying to repurpose EV batteries as vitality 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 growing EV manufacturing business, each when it comes to funding and expertise. There are a lot of causes for this, together with the financial viability of recycling batteries, the technological complexity of reprocessing diversified and quick evolving battery varieties, and logistical friction factors on account of regulatory points.
Environmental case for EV battery recycling
At the moment, 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 parts of batteries, corresponding to copper, nickel and lead, may be extremely poisonous. Because the batteries decay, these chemical compounds can leak into the encircling space, inflicting hurt to the native ecosystems.
Lead acid batteries current a threat, with one in three youngsters globally uncovered to guide poisoning on account 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 answerable for a discount of round 2% of GDP in Asia and 4% in Africa as a result of influence on productiveness in some communities. Enhancing the battery recycling price to battery disposal price ratio can cut back the dangerous influence of EVs on the surroundings—and on people.
Recycling may contribute extra broadly to the battle towards local weather change by way of the availability of commodities wanted to assist the vitality transition. These supplies additionally play a major position in facilitating the implementation of renewable vitality era strategies. For instance, photo voltaic and offshore wind must and 5 instances as a lot copper respectively than conventional vitality era strategies.
Historic underinvestment in mining initiatives, coupled with the lengthy lead instances for his or her growth, implies that the availability of metals like cobalt and copper will wrestle to maintain up with the demand pushed by the elevated use of renewables. Recycling the used metallic from batteries can assist the manufacture of a variety of unpolluted vitality 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 corporations and governments usually prioritise returns and profitability, you will need to additionally mirror on the financial advantages of accelerating the recycling price of EV batteries. First off, supporting the availability of key minerals will mood metallic costs which in any other case may surge uncontrollably. In flip, this controls the worth of EVs on the level of sale, making them extra accessible to the patron and accelerating their uptake and the shift in the direction of clear transport.
Nevertheless, the financial advantages are a lot wider than this. At the moment, recycling infrastructure and the recycling business is in want of great growth and additional funding. The growth of the business provide chains will create new jobs, increase financial exercise and spur development. The truth is, 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 brief time period, the markets for repurposing and recycling could compete for finish of life battery volumes, in the long term, there is no such thing as a doubt: the markets are complementary. Repurposed batteries will finally require recycling.
This development in itself can present a much-needed increase, particularly to areas corresponding to some African nations, the place the battery recycling business is extraordinarily underdeveloped. However past that, whereas these nations will profit from job creation, abilities diversification and elevated financial exercise, the repurposing of batteries can enhance their economies rather more instantly. Repurposed batteries can allow elevated vitality 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 drive for good. Nevertheless, there stay obstacles to the business’s growth which should be overcome whether it is to achieve its full potential. Differing rules implies that there are sometimes friction factors which stop or stall the transboundary motion of lithium-ion batteries for recycling and repurposing. Moreover, as batteries evolve to turn into extra environment friendly, longer lasting and safer, they turn into extra complicated—as does recycling them.
An answer may be present in offering extra transparency and knowledge on the battery cycle and its interval of utilisation within the EV. Making this data obtainable to related stakeholders, governments and firms can be certain that any specific battery is appropriate for recycling, conforms to related requirements, and has the mandatory parts 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 growing a ‘Battery Passport’, which is able to give each battery an id, performing as a digital twin of the battery to document vital data throughout its whole lifecycle. It should present end-users with key information about its materials provenance, chemical make-up, manufacturing historical past, in addition to relevant ESG and lifecycle necessities, based mostly on the great definition of a sustainable battery. This technical information might be collected from worth chain stakeholders together with mining corporations, 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 due to this fact create higher transparency throughout the worth chain and facilitate useful resource effectivity, life extension, secure second use and stronger battery recycling.
Extra broadly, the Battery Passport is a main exemplar of an engine-room initiative that may have severe governance influence that reaches all ranges of society. From serving to safeguard these on the coalface of manufacturing, to making sure the standard of a battery 1000’s of kilometres away to a shopper, the Battery Passport has the potential to the touch each facet of how we have interaction with the 21st century’s breakthrough electrical applied sciences.
