symmetric monoidal (∞,1)-category of spectra
A (quasi-)triangular Hopf algebra is a Hopf algebra whose underlying bialgebra is a (quasi-)triangular. This means that its category of modules is not just a rigid monoidal category but a braided monoidal category/symmetric monoidal category.
If this rigid symmetric monoidal category in addition satisfies a certain regularity condition (see here) then the corresponding triangular Hopf algebra is equivalent to a supercommutative Hopf algebra, hence to the formal dual of a affine algebraic supergroup. See at Deligne's theorem on tensor categories for more on this.

A quantum group (in the sense of Drinfeld-Jimbo) is a quasitriangular Hopf algebra.
The Drinfeld double of a Hopf algebra is a quasi-triangulated Hopf algebra?.
