More evidence of the LFP battery becoming the battery of choice in particular with BYD's blade battery, even for TESLA on its standard models.
Tesla announced in the context of its most recent financial results that it will switch these standard-range models to LFP batteries worldwide. Until now, Tesla has relied on LFP cells from CATL for the standard range models built in Shanghai.
BYD's blade battery has a bit of an edge in that packs constructed with the blade battery can currently achieve energy densities in excess of its competitors. Tesla batteries with CATL cells come to an energy density of 126 Wh/kg, but the blade batteries come to 150 Wh/kg.
In addition to the cobalt-free cell chemistry (as with all LFP cells), the blade batteries are also said to offer low costs. The portal PushEVs writes of “an estimated 55 euros per kilowatt-hour”, or 64 dollars/kWh. BYD itself also repeatedly emphasises the high safety of the blade battery compared to other lithium-ion batteries. Later, BYD stated in another announcement that the battery should last 1.2 million kilometres or 3,000 charging cycles.
No doubt CATL, pretty much in the lead on Sodium Ion battery chemistry development, and others will respond, catch up, overtake, as competition spurs rapid development.
