In a rare interview, Panasonic’s EV battery manager provided a glimpse of the company’s response to the much larger battery cells promoted by client Tesla. Talking to Bloomberg, Yasuaki Takamoto explained even bigger cells are the critical to affordable electric automobiles, but indicated he is not convinced by Tesla’s proposed cell format.
Tesla offered its 4680-structure cylindrical cell as its future all through its Battery Working day past year, but it hadn’t then produced any considerable volume of them. Musk presented it as possibly halving mobile price over time.
Long term Tesla cell will make electrical power, electrical power gains
At the time, Tesla said the format—46 millimeters large by 80 millimeters long—was the sweet place, letting for price tag reductions devoid of challenges with large-speed charging and thermal administration noticed with more substantial cells. For comparison, the Panasonic-supplied cells in the Design 3 and Product Y are 2170-format—21 millimeters extensive by 70 millimeters prolonged.
In the interview, Takamoto explained larger sized cells would permit truly economical EVs since fewer would be desired to electric power a automobile, saving on manufacturing expenses. Having said that, he however appeared to some degree skeptical of the bigger format.
The even bigger cells would also be tougher to deliver, are susceptible to overheating, and are more inclined to particle contamination, Takamoto claimed. That’s a recurrent lead to of battery fires, which occur when modest pieces of metal operate their way into a mobile and induce it to shorter circuit, he mentioned.
When those people remarks make it challenging to inform no matter whether Panasonic sees the 4680 structure as worthwhile, rival battery provider LG Chem could be ready to bounce on that bandwagon. A March report explained the South Korean enterprise is arranging to assist Tesla deliver the huge-structure cells beginning in 2023, quite possibly at a United States manufacturing facility.

Some of Tesla’s approaching autos will most likely depend on the even larger cells. In October, CEO Elon Musk claimed that the ramp-up of the Semi depends on how rapidly they can ramp up generation of the new cells. They could possibly also be significant for the Cybertruck.
Tesla is scheduling to ramp up production of the new cells beyond their current pilot line in California—eventually to its Texas factory, and maybe to Germany. In January, the business advertised battery-production jobs at equally web-sites on Twitter.
