This is not a general rule and many non-cooled and air-cooled batteries can hold up pretty well. The battery cooling becomes a limiting factor for DC charging, especially if multiple charging sessions are required per trip.

The Leaf limited battery life is mainly to its battery chemistry (LMO), although it arguably doesn't go to great lengths to ensure thermal stability of the pack.

The Leaf has went through many battery changes through out the years. The Gen 2 (2018+ model years) were NMC (532?) and then there was a change again in 2023 (811?).
