Hmmm... misschien er even de resultaten van het onderzoek van het Koreaans ministerie (v. land, infrastructuur en transport) er bij halen:
De hieronder omcirkelde opmerking is meer dan duidelijk: door slechte kwaliteit is de separator tussen de positieve en negatieve pool beschadigd

Ministerie?
Jouw link maakt gewag van een onderzoek van LG Chem zelf.
Moest het echt aan de cellen zelf liggen, waarom betreft het (voorlopig?) enkel Hyundai?
Voor wie maakt LG Chem batterijcellen? 5-6 automerken... ofzo?
Moest LG Chem daar echt iets verzwijgen dan gaan ze nog meer problemen krijgen...
Electrek meent dat wslk alle 77.000 Konas een recall krijgen.

In an official investigation into the issue in Korea, Hyundai claimed to have found the problem (via Korea Times):
“During the National Assembly audit on Thursday, Hyundai Motor President Seo Bo-shin, who is in charge of quality control, said the company “admits the defects in vehicles” and “has found a solution” to fix the defects, “though it is not perfect.””
However, different reports are coming to different conclusions.
One is putting the blame on the battery cells while another is concluding that it has to do with the battery pack:
“The ministry said it found “the separator in the battery cell was damaged due to errors in the manufacturing process,” indicating LG Chem’s battery cell could be the cause of fires. The National Forensic Service also came up with a similar conclusion that “electric problems in battery pack assembly” are assumed to have caused the fires.”
The Kona EV’s battery pack is made by HL Green Power; a joint venture of Hyundai Mobis and LG Chem, where the latter produces the battery cells and the former assembles the battery packs.
LG Chem denies that the cause could be the battery cells.
Hyundai already confirmed a voluntary recall of over 25,000 Kona EVs in Korea and the recall is now expected to be extended to over 77,000. electric vehicles worldwide, including in North America, most of the vehicles are in Europe.
Kona EV owners should stay tuned for an official announcement through NHTSA.
