Will blade batteries replace ternary lithium-ion batteries?

The above three data of the widely used ternary lithium power lithium battery are roughly like this: the life span is 800-1000 erasing and writing cycles. The energy density is 180KW/H (200KW/H is currently experiencing mass production difficulties), and the packaging efficiency is about 62%. To be honest, it's not great, but as far as the current battery technology is concerned, it is already the best. To understand that solid-state batteries are currently promising, the lifespan under laboratory conditions cannot even reach 50 cycles, and the energy density has just touched 100KW/H, which is far from ternary lithium. Then, let's feel the horror data of these three projects of BYD blade battery! The blade battery has a life of 3500 erase and write cycles, an energy density of 180KW/H (mass production data), and an astonishing 80% packaging efficiency! It is important to understand that these data are data of mass-produced blade batteries. Today's ternary lithium-ion battery technology development has begun to slow down, but the blade battery has just begun to enter the technological explosion period. And the more critical factor is not these technical things, but the cost! BYD's blade battery is based on lithium iron phosphate technology. The cost of this kind of thing is recognized to be lower than that of ternary lithium. The profit margin of BYD's new energy vehicles has always been higher than that of other brands, which is largely due to them. The low cost of our own lithium iron phosphate battery. However, traditional lithium iron phosphate batteries cannot become the mainstream of the market only because of insufficient energy density. This is why the lower safety and more unstable ternary lithium has always dominated the mainstream of power lithium batteries (of course, another part of the reason is At the time, BYD did not sell lithium iron phosphate). But now the blade battery has solved several pain points of traditional lithium iron phosphate, low-cost, ultra-high safety, high enough energy density, packaging efficiency and ternary lithium, and the key is open to external sales. In fact, it is really only BYD that can make a blade battery. First of all, the blade batteries used in pure electric vehicles must be based on lithium iron phosphate battery technology. Only with this technology can the internal structure be made into the narrow and long shape of the blade battery while maintaining large power storage capacity. . Secondly, at present, only BYD owns high iron phosphate lithium-ion batteries, and BYD itself is the world's largest manufacturer of mobile phone batteries, and has very relevant experience in manufacturing long and narrow batteries. So this technology should of course be obtained by BYD. For other power lithium battery manufacturers in the world, it was impossible in the Ningde era. LG Chem does not have lithium iron phosphate technology, and Panasonic batteries cannot handle CTP packaging. And according to reliable news, almost all car companies you know in the world are discussing the supply of blade batteries with BYD.
