Here’s How BYD’s Blade Battery Is Superior To Lithium-Ion Packs In Most EVs
Quote:
One of the significant concerns in EVs is battery safety, given that a violent crash can lead to the combustion and explosion of lithium-ion batteries. From Tesla to Hyundai, most EV makers have experienced battery fires from overheating and sometimes, for idiopathic reasons as well. It’s simple, to make EVs more feasible, the batteries have to be safer.
One of the advantages that Blade batteries offer in this context is the use of lithium iron phosphate (LFP) for the cathode material. This promises better safety than conventional lithium-ion batteries, given that LFP has more stable chemistry, even at temperatures as high as 930 °F (500 °C).
BYD’s Blade battery also passed the industry’s “Everest” test, which includes a nail puncture to prove that the battery would not ignite in case of an internal short circuit. While other batteries’ surface temperatures rose, enough to explode or char an egg dropped on them to test the same, the BYD battery remained at a cool 30-60 °C (85-140 °F), leaving the egg mostly unchanged and undamaged. This implies that BYD batteries stay cool under pressure and heat.
