I think this is the answer. That is also a problem for hybrid powers vehicles, the battery is small and it gets charged and discharged 0-100 / 100-0 very often, if you use the hybrid as intended.

Some manufacturers limit this, but in a few years we will see a lot of hybrids that have batteries that barely work and will not deliver the expected ev only distance by a lot.

A lot of Toyota hybrids (but I believe not PHEVs) use NiMH batteries, which are longer lasting than the Li-ion batteries used in EVs and can withstand more charge cycles.

They last longer because they are treated gently compared to lithium packs in EVs (shallow/frequency cycles, lower charge/discharge rates, etc).

When used in the same duty cycle, most lithium cells/packs should last longer than the same capacity NIMH cells/packs.

[teamonkey]

They’re used on hybrids because they’re more longer-lasting than Li-ion for the duty cycle hybrids have.

Li-ion is not universally better, but its energy density makes it better for EVs, and economies of scale mean that they’re becoming as cheap or cheaper than NiMH cells even if the hybrid duty cycle will make them degrade faster.

Not only that, those small batteries do cost a disproportionate amount of money to replace.
