Hilariously, after listening to the Transport Evolved video that New2Elec linked to, they clarified that the cells are the size of a playing card, but the modules will be the size of the a deck of playing cards. (7:45 in the vid)
So if we're gonna put our foot down about a battery being a module of cells, the article is perfectly correct anyways.
Presumably you'd need quite a lot of modules for an EV pack, with 100 cells per module. Brace yourself for people tearing apart electric VW batteries in 10 years, and calling the modules cells.
Video noted that they still haven't figured out how to mass produce and test cells nor have they tested them in actual vehicles. 2025 sounds optimistic.
EDIT:
According to
Merriam-Webster definition 4B:
a group of two or more cells (see CELL sense 5) connected together to furnish electric current
also :
a single cell that furnishes electric currentBut yeah lets act like arguing about it is productive.
It's not a big deal. In everyday english language, battery often refers to a collection of cells or a single cell being used as, well, a battery. That doesn't mean the words are interchangeable, nobody is claiming that they are.
