Not really. WordPad supported rtf and things like embedded images. It has been obsoleted by MS.
Notepad doesn’t do rtf, but they did add markdown support. Which I think is an ok feature. The bad part is the application now also includes AI and other unnecessary features and doesn’t feel as snappy and fast as the old one.
There’s always a catch, details matter.
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.
