The Blade Battery is actually a marketing name for BYD's LFP (lithium iron phosphate) batteries in the cell-to-pack approach, in which there are no modules and the batteries improve a vehicle’s structure.
"Multiple insider sources: #BYD to supply Tesla with blade battery starting 22Q2, Tesla model carrying BYD #battery entered C-sample testing phase."
We guess that the potential use of BYD's batteries might be related to the upcoming "cheap" Tesla that could start at around $25,000. The latest rumors say that Tesla already has a prototype of it.
We would not be surprised if the company used the LFP lithium-ion battery chemistry, which is considered the most affordable. Additionally, BYD's cells offer a possibility of structural integration, a thing that Tesla pursues.

BYD is in a process of expansion of its battery production and transition of its entire electric car portfolio to Blade Batteries (both BEVs and PHEVs). As there are more of those cells available, they will be sold also to other manufacturers.
CnEVPost recently reported a big 10% surge of BYD shares, bringing the market capitalization to more than over 880 billion CNY ($136 billion). It might not be accidental.
The company expects to sell 600,000 plug-ins this year, 820,000 in 2022 and about a million in 2023. The battery output would be 35 GWh, 51 GWh, and 70 GWh, respectively.
The average battery capacity (assuming all batteries would be used in BYD's EVs) would be then 58 kWh, 62 kWh, and 70 kWh per car.
