from chemistry to pack
AION Engineering INC While silicon (SiOx/SiC/Si) based anodes skyrocket battery capacity, their swelling character reaching up to 300% volume expansion transforms cell design from a purely electrochemical challenge into a brutal mechanical packaging problem. It is not just about how much lithium the active material can store; how the casing structurally resists (its rigidity) when … Read more
The Ferrari Elettrica has a 122kWh battery pack, 800V and cells made by SK On. Metrics Specifications Ferrari say quite a lot about the integration of the battery pack and the chassis.

A commonly used material for the pouch cell structure is aluminium laminated film. This pouch material typically consists of a layer of aluminium (Al), coated on the outside with a layer of nylon and/or polyethylene terephthalate (PET) and on the inside with a layer of polypropylene (PP). There are not many configurations of this material out there, most … Read more
When we talk about Stacked vs Wound cells we are considering the Anode-Separator-Cathode stack and how that is assembled within a battery cell. Kong et al [1] show a simple schematic of the two arrangements. Pouch and Prismatic cells can be stacked or wound, but what is the advantage and disadvantage of each approach? Cell … Read more

The 2022 Kia EV6 is an interesting vehicle, perhaps mostly because of the specifications around the battery pack. Specifications that have been achieved with some small steps in design. This platform is shared with the Hyundai Ioniq 5. The 2021 Hyundai Ioniq 5 pack had 30 modules and a total of 72.6kWh. In this design … Read more
How does the choice of cell format influence battery pack mass? The three main cell formats: Cylindrical, Prismatic and Pouch. There are pro’s and con’s with each. One of the most significant differences is the amount of mechanical support required. The pouch cell needs the most support and fixing, followed by the prismatic and the … Read more
