Nesting braces is already implemented in the classic org-latex.el[1],
and is forward ported into org-element.el.  Would you like to take a
look at the attached patch? Thanks.

If \ce{^2H} works as above, it is not a problem for me.  Although make
it configurable is more user-friendly; "^:{}" is already there afterall,
adding another style feels natural.
