Let’s develop a truly green process together for the recycling of lithium ion batteries!
What is key to a sustainable (EV) battery industry? It’s the efficient recovery of lithium and cobalt, two elements that raw material experts regard as critical due to their scarcity, cumbersome production and risk of supply. They are located in the cathode material of lithium ion batteries and, after discharging and dismantling, they can be recovered in a mixture called “black mass” together with other metal compounds.
Today, metals are recycled from black mass in energy-intensive smelting plants that release climate-damaging gases and fail to recover most of the lithium. Alternatively, hydrometallurgical approaches use aggressive chemicals and produce acidic waste piles that are costly to dispose of.
We believe these strategies belong to the past and envisage a truly green process for the recycling of (EV) batteries.
Dedicated microorganisms can, by producing organic acids, selectively dissolve lithium and cobalt and leave the remaining bulk material in the solid state. To support this bioleaching activity, microorganisms are fed, i.e. with a simple sugar, a carbon-rich waste stream such as beet syrup, crude glycerol from biodiesel production, or pomace from vegetable or fruit processing. Or even just with carbon dioxide. The latter could compensate for the whole amount of carbon dioxide released during the original production process.
An overview of the process is shown in this animation.
Microorganisms take over lithium and cobalt extraction and lead to a fully environmentally friendly and sustainable battery recycling process.
