A Batalin-Vilkovisky algebra or BV-algebra for short is
a Gerstenhaber algebra $(A, \cdot, [-,-])$
equipped with a unary linear operator $\Delta : A \to A$ of the same degree as the bracket
such that
$\Delta$ is a derivation for $[-,-]$;
$[-,-]$ is the failure of $\Delta$ being a derivation for $\cdot$:
A $(n+1)$-BV algebra is a similar structure with a BV-operator being of degree $n$ if $n$ is odd, and of degree $n/2$ if it is even.
See (Cohen-Voronov, def. 5.3.1, theorem 2.1.3) for details.
The operad for BV-algebras is the homology of the framed little 2-disk operad.
This is due to (Getzler)
The homology of an algebra over an operad over the framed little n-disk operad has a natural structure of an $(n+1)$-BV-algebra.
This appears as (CohenVoronov, theorem 5.3.3). The full homology of the framed little n-disk operad is described by (SalvatoreWahl, theorem 5.4).
Multivector fields may be identified with Hochschild cohomology in good cases (the Hochschild-Kostant-Rosenberg theorem). So the next example is a generalization of the previous one.
The identification o BV-algebras as algebras over the homology of the framed little disk operad is due to
The generalization to higher dimensional framed little disks is discussed in

There are examples coming from Lagrangian intersection theory
The BV-algebra structure on multivector fields on an oriented smooth manifold is discussed for instance in section 2 of

There is a prominent class of examples coming from Lie-Rinehart algebras
