Why we need Storage alternatives to lithium
The majority of homeowners rely on lithium storage to use their self-produced solar energy around the clock – due to a lack of alternatives. However, the life cycle of a lithium battery shows that this type of storage is to be questioned in ecological and humanitarian terms. Thanks to vanadium redox flow technology, we are the first to offer a sustainable and powerful alternative. It is finally time to take a new path
A detriment to man and nature: the extraction of lithium.
The aggravated problem: lithium recycling in comparison.
The lithium battery cells are melted down at high temperatures in a blast furnace, requiring lots of energy.
Raw material separation
During the blast furnace process, the raw materials cobalt and manganese can be removed at different melting points.
At the end of the melting process, a slag consisting of lithium, iron and aluminium remains. Lithium can be removed from this slag in a very complex and costly custom procedure.
Use for concrete industry
The custom procedure for removing lithium from the slag is often unprofitable. The iron-containing lithium slag is therefore removed from the recycling cycle and used in the concrete industry instead.
The vanadium dissolved in the electrolyte liquid is heated to only 70 degrees in a low-energy process. As a result, the dissolved vanadium returns to its solid state and settles at the bottom of the electrolyte container.
After the solidified vanadium has settled at the bottom of the electrolyte container, it can be filtered out of the liquid.
