Sony has been promising to enter the EV battery business since the golden age of the LiFePO4 cells in 2010.
But now the company is finally close to start supplying cells for EV batteries.
Sony has recently released its new 3.000 mAh 18650 cell, the VCT6, which is still behind the 3.500 mAh cells that Sanyo, LG Chem and Samsung SDI already produce in the same cylindrical format. Yet the Sony VC7 cell is coming and it will match the 3.500 mAh capacity.
This is especially important for battery makers that use 18650 cylindrical cells. Such as Kreisel Electric or Imecar.
The 18650 cells are great for third party battery makers, since their tiny size allows them to adapt to any battery pack. But for electric car makers, prismatic or pouch cells are preferable since they make the task of building a battery pack a lot easier. This is why Sony’s intention to become the Formula E cell supplier is important.
According to motorsport.com Panasonic and Sony have submitted tenders for the Formula E 2018 battery deal.
Currently Xalt Energy supplies cells for each Formula E battery developed by Williams.
Even if Sony isn’t chosen to be the Formula E cell supplier, it doesn’t matter. Sony is preparing to become a major cell supplier for electric vehicles batteries.
The more choice the better, this is great news.
