When to use it

&ell; writes U+2113 (Script Small L), a small letter from the Unicode Letterlike Symbols block, encoded since Unicode 1.1. These characters exist mostly for compatibility with older character sets; for anything beyond simple cases, <sup>, <sub> or MathML give more control.

The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
