    • Polestar reveals that it will use SK On pouch-type batteries with high nickel content in the 2025 Polestar 5, four-door GT.
    • The pouch-type cells produced by South Korea’s SK On promise higher energy density, quicker recharge cycles, a longer range, and greater thermal security.
    • The GT’s four doors will compete against several other luxury electric cars currently on the market. This segment has received a lot of attention over the last few years, but it could be heading for a cooling phase.
  • We’ve known for a while that Polestar’s electric flagship would aim to offer buyers performance and range, with the EV maker set to make a statement with the arrival of its sleek and chiseled four-door GT.
  • Polestar hasn’t revealed the type of battery that will be used in its 2025 electric vehicle.

  • Polestar chose the pouch-type batteries of South Korean battery manufacturer SK On because they have a high nickel content. These innovative cells have a nickel content that is almost 90%. This means they will offer a higher energy density, a longer driving distance, and faster recharge cycles.

  • Polestar CEO Thomas Ingenlath stated that Polestar 5 was developing quickly and would feature a high-capacity lithium battery in order to deliver the performance of ‘our grand tourer.
  • When stacking separators inside the battery, the battery maker uses a Z folding technique to create ultra-long pouch-type 56-cm batteries. The walls will be stacked in a zigzag pattern to avoid contact between cathodes and anodes. This also reduces stress on the storm.
  • The separator wraps the cathode with perfect alignment and allows for complete separation. The battery manufacturer notes that this reduces the chances of anode and cathode contacting on their outer edges.
  • SK On’s Z-folding technique is claimed to yield much greater thermal safety, as well as greater energy density, than other current types of lithium-ion batteries.
  • SK ON
  • SK On says that the Z-folding method is also not susceptible to misalignment that may occur in battery components due to driving at high speeds, a problem that has been given relatively little attention when discussing battery safety.
  • The company claims that SK On batteries have never caused a battery fire in the 2.5 million electric cars they’ve been installed in. SK On provides batteries for the Ford F-150 Lightning, as well as EVs by VW Group and Hyundai.

The incident, among other things, should serve as a case study for what happens when robotaxis is involved in a crash that is already underway, triggered by a car. This had not occurred in the US before October.

It is a bit surprising that the robotaxi didn’t already have the programming in place to make sure it would stop if a pedestrian was hit and stay in place. Or that it lacked sensors to detect the situation.

It is at least foreseeable that, whether the robotaxi was to blame or not, a pedestrian would become trapped underneath the vehicle. The car must remain in position.

It is known that robotaxis have a coding system to govern their behavior when solid objects are driven over, like traffic cones. However, it is unknown to what extent a Cruise Robotaxi can classify these objects and make appropriate decisions.

Cruise previously claimed, in defense of its robotaxi, that the car began braking 460 milliseconds before a pedestrian was detected walking into its path. This is much faster than any human being could react.
