Volvo is implementing traceability of cobalt used in its EV batteries using Blockchain technology to ensure materials have been responsibly sourced.
There is an argument that materials used in the production of batteries for electric cars are as big a contributor to emissions as the running of an ICE car, and that the materials used in production are not sustainable.
But that can be mitigated to a degree by ensuring the materials used are responsibly sourced, so Volvo are going the extra mile to ensure that in future the batteries used in their EVs – like the new XC40 Recharge – and plug-in hybrids can be tracked from source to battery.
Volvo will use Blockchain technology to ensure a fully traceable path for materials like cobalt, which means the information about the supply path is spread across a wide network linked by cryptography, making it all but impossible to make undetected changes to the information.
Of course, Volvo isn’t the maker of its batteries, so it’s had to enlist the co-operation of CATL and LG Chem, which do produce their batteries, and leading global Blockchain technology firms, to ensure the new traceability system is in place.
Martina Buchhauser, Head of Procurement at Volvo, said:
We have always been committed to an ethical supply chain for our raw materials.
With blockchain technology we can take the next step towards ensuring full traceability of our supply chain and minimising any related risks, in close collaboration with our suppliers.
So if you’re concerned about the sustainability and source of EV batteries, you’ve just found another reason to choose a Volvo.
