Ann: AnteoTech secures $1.4m Qld Grant Funding, page-125

Thanks Captain , Very informative post as usual , Who uses pouch cells in their EV's ? quite a few including Hyundai and Ford and many others use pouch cells in their vehicles but not Tesla ? In addition to their customizable, lightweight designs, pouch cells might be the first step to an even better EV battery option: solid state?

Pouch cells looks well suited to Anteo's 70% plus high silicon anode tech is a semi solid state pouch cell now that should have a much higher energy retention and the safety breakthrough the market is looking for , Happy easter ADO investors .

What Are The Advantages And Disadvantages Of Pouch Cell

Pouch cells definitely have their place in society. They can often produce far higher currents than canister cells and they can be made to fit odd spaces more easily and are more energy dense.
Advantages

● The polymer separator and aluminum foil casing makes them light
● Pouch cells can deliver more current than a cylindrical cell of the same size
● Lower internal resistance
● Can be made in many sizes and shapes
● Higher energy density
Disadvantages

● Complicated to manufacture
● Easy to puncture
● Under heavy use they swell a lot
● Under normal use they swell somewhat



Differences Between Pouch And Cylindrical Cells

Pouch cells can deliver more current and can be made to fit just about any shape or size. Cylindrical cells, on the other hand, are strong and have good heat dissipation characteristics.
Pouch cells will expand over the life of the battery pack whereas cylindrical cells stay the same size. The phenomenon plays a key role in properly designing a system to use pouch cells. When you are using pouch cells much more care has to be taken in terms of where the battery will go and the room inside that cavity.
Cylindrical cells, on the other hand, always stay the same size. This is because they have a hard metal case and are designed in such a way that they do not expand under normal operation. Personally, I feel like this is the key attribute that makes cylindrical cells the better option in most cases.
Is The Packing Efficiency Of Pouch Cells Higher Than Cylindrical Cells

Yes. Pouch cells have a higher internal energy density and can be packed very efficiently. Cylinder cells have a packing efficiency of about 90 percent. This is in contrast to pouch cells that can have packing efficiencies as high as 99 percent. So in a given space with a cylindrical cell, you will have about 9% dead space compared to pouch cells.
No matter how much effort you put in, you won’t be able to fill all of the space with cylindrical cells because they have a circular footprint. Circle packing is a highly complicated science and it can get really overwhelming, really quick, but I will tell you this: The hexagonal pattern is the most efficient packing format you can use for cylindrical cells.
