GM is considering incorporating cylindrical batteries into its electric vehicles rather than the present package options. Other prominent automakers are either already considering this alternative strategy or are considering doing so.
GM's new choice resulted in the halt of the construction of a new facility jointly with LG, according to The Elec, which cited industry sources. In the meantime, the automaker is working on the final transition to cylindrical versions, which are expected to be implemented in future models.
According to reports, GM intends to select 4680 batteries, the same ones used by Tesla. According to the publication, other electric vehicle manufacturers such as BMW, Volvo, and Stellantis are also considering their use. It is believed that 4680 batteries are better suited for electric vehicles than other cylindrical versions.
The process of fabricating anodes, cathodes, and separators, and storing them in cylindrical cases, as well as packet or prismatic batteries, is fairly straightforward. Because there is quite a lot of free space when packed in large blocks, cylindrical batteries are typically quite simple.
The use of long cylindrical batteries of the type 4680, with a length of 80 mm, makes their use more efficient, and there is less free room when packing. This package is even more compact due to special modifications.
In the face of rising costs in the sector, General Motors has decided to switch to cylindrical batteries. They are the oldest type, so manufacturers have long developed their manufacturing techniques and have many solutions to reduce production costs.
