symmetric monoidal (∞,1)-category of spectra
For $n \in \mathbb{N}$, a Poisson $n$-algebra $A$ is a Poisson algebra $A$ in a category of chain complexes with Poisson bracket of degree $(1-n)$ (which is a bracket of degree 0 on $\mathbf{B}^{n-1} A$).
The homology of an E-n algebra for $n \geq 2$ is a Poisson $n$-algebra.
Moreover, in chain complexes over a field of characteristic 0 the E-n operad is formal, hence equivalent to its homology, and so in this context $E_n$-algebras are equivalent to Poisson $n$-algebras.
This fact is a higher analog of Kontsevich formality. It means that every higher dimensional prequantum field theory giveny by a $P_n$ algebra does have a deformation quantization (as factorization algebras) and that the space of choice of these a torsor over the automorphism infinity-group of $E_n$, a higher analog of the Grothendieck-Teichmüller group.

There is a forgetful functor from Poisson $n$-algebras to dg-Lie algebras given by forgetting the associative algebra structure and by shifting the underlying chain complex by $(n-1)$.
Conversely, this functor has a derived left adjoint which sends a dg-Lie algebra $(\mathfrak{g},d)$ to its universal enveloping Poisson n-algebra $(Sym(\mathfrak{g}[n-1], d))$. (See also Gwilliam, section 4.5).
A Poisson 1-algebra is a Poisson algebra.
A Poisson 2-algebra is a Gerstenhaber algebra.
The Chevalley-Eilenberg algebra of a symplectic Lie n-algebroid (see there for details) is naturally a Poisson $(1+n)$-algebra.
A classical BV complex is naturally (if obtained as a derived critical locus, or else by definition) a Poisson 0-algebra.
