Did General Motors just drop its ULTIUM battery?

General Motors is reportedly planning to switch from pouch cells to cylindrical cells in its future electric vehicles – and the sudden change in direction has apparently caused a bit of a rift in the relationship with its primary #battery supplier, LG Energy Solutions: According to theelec, talks between GM and LGES about a planned factory in Indiana have ended, and GM is said to be reaching out to other battery manufacturers.

The cylindrical cells GM intends to use are the 4680 format, which were first introduced by #Tesla.

These cells may be easier to produce than pouch cells (you just got to love a good roll-to-roll process!), and (like all other form factors) are praised to be the best one around.

But I believe that their main appeal to GM is their standardisation.

The shift from pouch cells to cylindrical cells is not a new trend, as BMW has already announced its transition from prismatic cells to cylindrical battery cells for its EVs. With more and more automakers moving towards cylindrical cells, it will be interesting to see how this affects the battery market and the race to produce the best and most cost-effective batteries for EVs. So, buckle up and get ready for a thrilling battery cell ride, as the automotive industry prepares for a power-packed and electrifying future!
