BMW i7
BMW is testing state batteries “truly” solid in i7. Sulfide -based batteries promise greater energy density, greater safety and more versatile and compact packaging compared to traditional lithium -ion batteries.
Has just reached a historic milestone in the matter of Solid state batteries.
The German construction company announced this week that it is testing the concept of solid state battery cells (ASSB) of the batteries expert Solid Powerheadquartered in Colorado (USA), in its electric i7.
Batteries that are being tested combine prismatic cells and concepts of new and innovative modules.
“Solid Power is extremely proud that our partnership with BMW has resulted in the first demonstration of truly solid battery cells in a vehicle,” he said John Van ScoterPresident of the American company, quoted by.
BMW and Solid Power have systematically highlighted these batteries as “Totally truly in solid state”.
According to New Atlas, these constant references are due to the fact that the main competitor of BMW, A, announced a similar collaboration last February, starting solid state cell tests in its electric flag, EQS.
BMW with good advance
Unlike the Solid Power cells that BMW is testing, the batteries Factorial Electrolyte System Technology that a Mercedes tested they use an almost solid (or semi-solid) electrolyte and They are not technically “totally solid” – That is, without liquid.
As New Atlas repairs, the factorial itself describes this electrolyte as a hybrid between liquid and solidwhich comprises a “solid matrix infused with a liquid electrolyte or gel type”.
The solid state batteries that previously found themselves from Chinese automotive manufacturers, such as IM, are also from the variety of semi-solid state, so BMW and Solid Power seem to be right from their statement of “first solid state batteries integration in a production vehicle”.
Still, the distinction is purely academic and the only “first” that will eventually count is the car manufacturer that truly introduces solid state technology into the market. Still, BMW is already in good advance.
BMW has been working on the development of solid state batteries with Solid Power since 2016.
Although road tests obviously represent an important step for the eventual launch of solid state batteries, BMW admits in this announcement that “more development steps are needed to implement ASSB technology in a competitive global storage system.”
“In other words, Do not expect to see the solid state i7 in dealers in the immediate future“underlines New Atlas.
