Brandende accu's. De accu's in een Tesla S zijn van het LiFePo4 type.

Nope, wel het NCA type en 2 types 2012/2016 voor model S:

Tesla uses NCA chemistry, or Nickel, Cobalt, and Aluminium (LiNiCoAlO2).

They use this particular chemistry because it offers great energy density, long cycle life, and great charge performance. This makes Tesla’s batteries the absolute top of the line in the EV world. They weigh less, last longer, and power the performance of things like Ludicrous mode.

Tesla’s Batteries have gone through 3 stages: Stage 1 was from 2009-2012 found in the Roadster and Model S. Stage 2 was from 2016-2018 and powered the Model S Gen II, and the Model X. Stage 3 starts with the Model 3 in 2018.

Stage 1 batteries were constructed with 18650 cells, which are 18 mm wide, and 65 mm tall. They had a NCA formulation that required 11kgs of Cobalt in the cathode, per car. They had a pure graphite anode, with no Silicon.

Stage 2 batteries used the same 18650 cells, but reduced the amount of Cobalt required in the cathode from 11 to just 7kg/car. They also introduced a small amount of silicon into their anode.

Stage 3 batteries are new for Tesla, and first shipped with the Model 3. Stage 3 batteries have further reduced the amount of cobalt to just around 4.5kg per vehicle. They also have a hybrid silicon/graphite anode, and while proprietary and unreported, probably higher silicon content than their stage 2 batteries.
