Some chemistries can only work if heated up to a certain temperature.
Some cannot supply high currents.
Some perform badly at lower temperatures.
Some are expensive to produce.
Some have a very low energy density per weight or volume.
Some are hard to create consistently and require a lot of balancing.
Some cannot be scaled up easily.
Some are prone to aging regardless of cycles.
Some even require manual maintenance.
It’s hard to make a cell that does everything right. Cycle life is only one out of a huge list of parameters.
There’s always a catch, details matter.
