How does the Audi e-Tron's battery technology differ from other electric cars?

I've heard that the Audi e-Tron has a unique battery setup, but I'm not sure exactly how it differs from other electric cars. Can someone explain?

The Audi e-Tron uses a lithium-ion battery with pouch cell technology, which allows for a more efficient use of space and increased energy density compared to cylindrical cell batteries. This means the e-Tron can have a longer range and faster charging times.

In addition to its lithium-ion battery, the e-Tron also has a unique cooling system that helps maintain optimal battery temperature. This can help extend the life of the battery and improve performance.
