From China there are some very interesting rumors concerning BYD and Tesla . It seems that BYD could supply the American manufacturer with its batteries called & quot; Blade Battery & quot ;. The two companies they did not want to comment on these rumors but according to reports, the brand would already be; testing the new batteries and the supply should start in the second quarter of 2022 .
The accumulators that BYD presented last year have some very specific characteristics. In battery packs, cells that have a & quot; blade & quot; shape (hence the name Blade) are assembled with the cell-to-pack method . This choice, which does not provide for the subdivision of the cells into modules, saves valuable space. Furthermore, the cells are of the LFP type (lithium-iron-phosphate). Therefore, they use the same chemistry of the batteries supplied by CATL for some models built by Tesla inside the Shanghai factory.
This chemistry makes it possible to make the batteries more efficient. safe and more & ugrave; economic . Furthermore, it guarantees the accumulators a good duration over time. However, LFP cells tend to & quot; suffer & quot; low temperatures and offer a density; energy more & ugrave; low, compensated, in the specific case, by the possibility; to insert more & ugrave; cells in the battery pack thanks to their particular arrangement.
AGREEMENT FOR MODEL 2? 
The arrival of these rumors a few days after the rumor that the $ 25,000 Tesla prototype was ready immediately made one think that the two news could be somehow related. The characteristics of the Blade Battery would be perfect for the & quot; small & quot; Tesla that many already they call Model 2 . The higher cost low LFP cells and cell-to-pack technology would perfectly match the design of this model.
All this also considering that the mass production of the 4680 cells designed by Tesla it seems not yet close. The American manufacturer, therefore, may have found an alternative to be able to bring its new car to market in a reasonable time. Obviously, these are speculations that must be taken as such since there are no official confirmations from the companies concerned.
All that remains is, therefore, to wait for further news to understand if BYD will indeed become & agrave; a Tesla supplier and on which models its batteries will be used.
